    Abstract Different cultivars of aplant species can affect the foraging and efficiency of natural enemies, both directly through physical and biochemical properties or indirectly through the herbivore's diet. In this study, the parasitism capacity and functional response of Diaeretiella rapae McIntosh were determined on the cabbage aphid, Brevicoryne brassicae (L.) reared on susceptible (Opera) and resistant (Okapi) canola cultivars under laboratory conditions at 25 ± 1 °C, 60 ± 5% RH and a16:8 h L:D photoperiod. The parasitoid exhibited Type II and Type III functional responses on the resistant and susceptible cultivars, respectively. The estimated value of searching efficiency ( a ) was 0.1637 ± 0.1095 h −1 on the resistant cultivar whereas its value was dependent on host density on the susceptible cultivar. The handling times ( T h ) on the susceptible and resistant canola cultivars were 0.108 ± 0.040 and 0.320 ± 0.048 h, respectively. The net parasitism rate ( C 0 ) of the parasitoid wasp varied from 128.09 hosts per parasitoid lifetime on the susceptible to 71.01hosts on the resistant canola cultivar. The transformation rate from host population to parasitoid offspring ( Qp ) was equal to 1 on both cultivars ( C 0 = R 0 ). The finite parasitism rate ( ω ) on the susceptible cultivar (0.819 hosts per parasitoid per day) was significantly higher than that on the resistant one (0.578 hosts per parasitoid per day). In conclusion, canola cultivars affected the performance of D. rapae in controlled small-scale laboratory experiments and compared with the susceptible cultivar, the resistant one had anadverseeffect on the efficiency of the parasitoid. Highlights Resistant cultivar had a negative effect on efficiency of the parasitoid, D. rapae . Functional response of the parasitoid was affected by the canola cultivars. The parasitoid exhibited a type II functional response on the resistant cultivar. Sex ratio of the parasitoid was almost equal on both cultivars. Graphical abstract [DISPLAY OMISSION]

    Abstract Entomopathogenic fungi have great potential to control agricultural and horticultural insect pests, however optimizing conidial production systems to demonstrate high productivity and stability still needs additional efforts for successful field application and industrialization. Although many virulent entomopathogenic fungal isolates have been viewed as potential candidates in a laboratory environment, very few of the isolates are being used in practice for application in agricultural fields as commercial products. I. javanicus is an entomopathogenic fungus that is parasitic to various diverse coleopteran and lepidopteran insects and thought good candidate as biopesticdes. In this work, the basic characteristics of two entomopathogenic fungi, I. javanica FG340 and Pf04, were investigated in morphological examinations, genetic identification, and virulence against Thrips palmi , and then the feasibility of various grains substrates for conidial production was assessed, particularly focusing on conidial productivity and thermotolerance. Isaria javanica FG340 and Pf04 conidia were solid-cultured on 12 grains for 14 days in a Petri dish. Of the tested Italian millet, perilla seed, millet and barley-based cultures showed high conidial production. The four-grain media yielded >1 × 10 9 conidia/g of I. javanica FG340 and Pf04. Pf04 strain had enhanced thermotolerance up to 45 °C when cultured on Italian millet. In application, it was easy to make a conidial suspension using the cultured grains, and several surfactants were tested to release the conidia. This work suggests several possible inexpensive grain substrates by which to promote conidial production combined with enhanced stability against exposure to high temperature. Highlights Entomopathogenic fungi FG340 and Pf04 were identified as Isaria javanica. Italian millet, perilla seed, millet and barley-based cultures showed high conidial production. Highly thermotolerant conidia were produced on Italian millet as substrates in the Pf04. Graphical abstract [DISPLAY OMISSION]

    Abstract Urban landscapes provide unique environments for a wide variety of plants and animals, but their suitability may be limited by anthropogenic impacts such as pollution. We examined the potential utility of lichen and lichen-feeding moths as biodindicators of air pollution in Hong Kong by comparing carbon (C) and nitrogen (N) stable isotope values in lichens, lichenivorous and non-lichenivorous moths (Lepidoptera: Erebidae) and a moth outgroup (Lepidoptera: Geometridae). Our results show that stable isotope values for C and N were similar for lichens and lichen feeding moths, while non-lichen feeding moths formed a distinct group. In addition, we found consistent δ 13 C and δ 15 N values across moth body parts, indicating that any portion of the specimen is suitable for isotopic fingerprinting. Our results highlight that lichen feeding moths may be useful for integrating signals of atmospheric nitrogen pollution and could therefore have utility in monitoring and quantifying air quality over time and space. Highlights No significant difference in C or N isotopes between body parts Moths with lichenivorous larvae have similar isotopic values to lichens. Larval lichenivory distinguishes related moth groups. Graphical abstract [DISPLAY OMISSION]

    초록

    Abstract The understanding of host specificity of predacious insects is one of the most important problems in the investigation of biological control. Prey preference and the potential for prey switching in Anthocoris minki Dohrn (Hem.: Anthocoridae) was assessed in two- choice experiments under environmentally controlled conditions. Manly's preference index was used to compare A. minki predation on Agonoscena pistaciae Burckhardt and Lauterer (Hem.: Psyllidae) versus Psyllopsis repens Loginova (Hem.: Psyllidae) but showed no statistically significant evidence for preference. Anthocoris minki did prefer psyllids ( Agonoscena pistaciae and Psyllopsis repens ) over aphids ( Forda hirsuta Mordvilko (Hem.: Pemphigidae) and Aphis craccivora Koch (Hem.: Aphididae)). The predator also consumed significantly more 2nd instar than 4th instar nymphs of P. repens . Switching behavior experiments showed that A. minki did not preferentially attack the most abundant prey when the prey combination was either biased toward A. pistaciae or toward F. hirsuta . Linear regression between preference indices and prey ratios indicated an overall preference for psyllids over aphids. The results suggest that a psyllid-specialized feeder such as A. minki is more likely to be effective biocontrol agent against psyllid species and less effective at reducing the numbers of other pest species that might co-occur with psyllids. Highlights Anthocoris minki had a strong prey preference for psyllids over aphids. The Manly's indices of Anthocoris minki for two different species of psyllids were not significantly different. Anthocoris minki didn't show switching behavior in different ratios of it's preys. Graphical abstract [DISPLAY OMISSION]

    Abstract Floral visual and olfactory cues guide the insect visitors to the source of reward. This work addresses one such interaction between honeybee Apis cerana and a garden climber Jacquemontia pentanthos . Field studies have indicated that A. cerana showed preference to J. pentanthos over the other flowering plants during its visits for foraging. The objectives of the work is to understand the role of colour and scent in the attraction of Apis cerana to the host plant. Bioassays performed emphasized the involvement of colour and volatiles for the visits of A. cerana . Petals show high reflectance to ultraviolet light with ultraviolet absorbing regions in the centre which serve as a nectar guide. Gas chromatography linked electroanntenogram detector (GC-EAD) showed antennal response to the floral volatile of J. pentanthos identified as sesquiterpene β-caryophyllene. Behavioural studies have shown similar preference to β- caryophyllene as that of α-humulene. Our studies suggest an interplay of colour and volatiles cues for A. cerana visitation to Jacquemontia flowers and these findings are further supported by behavioural studies on. A. cerana. Highlights In our study we have investigated the preference of Apis cerana to Jacquemontia pentanthose. We studied the importance of colour cues and olfactory cues of the flower in the identification of the host. Behaviour experiments and GC –EAD were performed to elucidate the role of colour and scent as an attractant Our finding suggests that there is an interplay of colour and scent is responsible for attraction of Apis cerana to the host. The volatile β-caryophyllene and α-humulene could be responsible in attracting Apis cerana to the host plant. Graphical abstract [DISPLAY OMISSION]

    초록

    Abstract Muscidae are a dipteran family which is important for forensic investigations. However, it has received limited attention in forensic entomological experiments as a reason of identification issues. It is hard to identify specimens by morphological methods, especially in developmental stages. Therefore, complete mitochondrial genome sequences can be important tool in forensic entomology for identifying species. In this study we sequenced and analyzed the first complete mitochondrial genome from a forensically important Muscidae species Hydrotaea (=Ophyra) chalcogaster by next-generation sequencing. The mitochondrial genome of the sequenced species is circular molecules of 17,076 bp which have the typical mitochondrial genome complement of 13 protein-coding genes, 22 tRNAs, two ribosomal RNA genes and a control region. Rearrangements of gene positions are identical with the ancestral insect genome. Furthermore, phylogenetic relationships of the family Muscidae were evaluated in regard to mitochondrial protein coding genes. The inferred trees indicate that the Muscidae is a paraphyletic family. These data provide additional information for molecular identification of muscid species. Highlights Hydrotaea chalcogaster has importance for forensic investigations. The mitochondrial genome of Hydrotaea chalcogaster sequenced and analyzed. This is the second complete mitochondrial genome from the genus Hydrotaea. Phylogenetic analysis supports monophyly of the superfamily Muscoidea. Graphical abstract [DISPLAY OMISSION]

    Abstract The brown planthopper, Nilaparvata lugens (StAl) is an important pest in rice. It has been widely recognized that the juvenile hormone (JH) is regulated by its hydrolase, which includes juvenile hormone esterase (JHE), juvenile hormone epoxide hydrolase (JHEH) and juvenile hormone diol kinase (JHDK). In this paper, we cloned the gene of Jhdk and the gene expression at different stages of N. lugens was analysed, and the relationship with Jhe and Jheh was studied after silencing the jhdk gene of N. lugens ( Nljhdk) through double-stranded RNA (dsRNA) feeding. We also explored the expression of the three JH hydrolase after indoxacarb treatments. RT-PCR was used to amplify the full length Jhdk cDNA, and the Nljhdk gene was expressed throughout all the development periods tested and showed the lowest level at the 4th instar and the highest in the 5th instar. The expression level of Nljhdk in male adults was higher than that of female adults. Through feeding, dsRNA against Nljhdk successfully knocked down the target gene, which had no significant effect on the expression of the jhe gene of N. lugens ( Nljhe ), while the expression of Nljheh was upregulated. Indoxacarb could inhibit N. lugens reproduction, and the expression level of Nljhe and Nljhdk increased with the increasing of indoxacarb concentration, but the expression of the jheh gene of N. lugens ( Nljheh ) was reduced. These studies provide a line of experimental evidence in N. lugens to support that Nljhdk encodes the functional protein involved in JH degradation and further showed the relationship of the three hydrolases and the mechanism of indoxacarb inhibition of the fecundity of N. lugens . Highlights Nljhdk was expressed the lowest at the 4th and the highest in the 5th instar. The expression of Nljheh was upregulated after the Nljhdk gene was knocked down. After indoxacarb treatments, the expression of Nljheh was reduced. After indoxacarb treatments, the expression of Nljhe and Nljhdk was upregulated. Graphical abstract [DISPLAY OMISSION]

    Abstract Two Grapholita species ( G. molesta and G. dimorpha ) cause serious losses in apple production by means of direct fruit damage and destruction. These two congeners occurred at similar seasons in the same orchards. Furthermore, the two species occurred in similar population sizes in apple orchards, though G. molesta occurred much more in total occurrence density than did G. dimorpha in a pear orchard. The two species share two major sex pheromone components, ( Z )-8-dodecenyl acetate ( Z 8-12:Ac) and ( E )-8-dodecenyl acetate ( E 8-12:Ac), but differ with regard to the relative mixture ratio necessary to create conditions of maximal attraction. To develop a simultaneous mating disruption (SMD), a mass ratio of 95:5 of Z 8-12:Ac and E 8-12:Ac was selected due to its high cross-calling activity and subsequent high mating disruption against both species. When the mixture was applied to orchards, it resulted in significant mating disruption against both species. However, mating disruption efficacy was slightly higher in G. dimorpha than in G. molesta . Application dose and dispenser type affected efficacy duration of SMD. In addition, the high density occurrence of G. molesta significantly reduced the SMD efficacy. Using a wax-type of dispenser, an application of SMD in 100 g per hectare dispersed in early spring recorded >90% mating disruption efficacy through the entire growing season against both Grapholita species. Highlights Two Grapholita species share major sex pheromone components. Simultaneous mating disruption (SMD) has been devised using cross-attracting sex pheromone composition. SMD application resulted in >90% mating disruption against both species. Graphical abstract [DISPLAY OMISSION]

    Abstract Six monoterpenes, ((−)-citronellal, p -cymene, (−)-menthone, α -pinene, α -terpinene and (−)-terpinen-4-ol) and two phenylpropenes, ( trans -cinnamaldehyde and eugenol) were tested for their insecticidal activity against the rice weevil, Sitophilus oryzae under laboratory conditions. The bioassays were carried out on wheat at the concentrations of 0.5, 1.0 and 5.0 g/kg. Adult mortality was assessed after 14 days of exposure. After this interval, the treated wheat was retained for an additional period of 90 days, in order to evaluate progeny production and wheat loss. At the concentrations of 0.5 and 1.0 g/kg, trans -cinnamaldehyde and eugenol achieved highest adult mortality. At 5.0 g/kg, all compounds except for p -cymene and α -pinene caused complete (100%) adult mortality. Generally, trans -cinnamaldehyde was the most potent compound causing complete inhibition of progeny at the three concentrations. Similarly, no progeny were observed in the wheat treated with (−)-citronellal, eugenol, p -cymene, (−)-menthone, and (−)-terpinen-4-ol at 5.0 g/kg after 45 and 90 days. Similar trends were noted for wheat weight loss and damage as the treatment with monoterpenes and phenylpropenes at the highest rate preserved the wheat intact and free from damage by S. oryzae for 90 days. Our findings suggest the tested compounds except p -cymene and α-pinene could be recommended for use as part of an integrated pest management program for S. oryzae control in stored wheat. Highlights Four monoterpenes and two phenylpropenes were found to cause significant adult mortality of S. oryzae in stored wheat. Highest adult mortality was observed with trans -cinnamaldehyde and eugenol. No progeny were produced in wheat treated with trans -cinnamaldehyde after 90 days. Monoterpenes and phenylpropenes treatments reduced wheat weight loss caused by S. oryzae . Graphical abstract [DISPLAY OMISSION]
