Baculoviridae; Spodoptera litura; biopesticides; body size; instars; juvenile hormones; larvae; pyriproxyfen
Abstract:
... Efficient production is essential for developing baculoviruses into marketable bioinsecticides. In this study, we evaluated how juvenile hormone (JH) III and the JH analog pyriproxyfen affected the production efficiency of Spodoptera litura (Fabricius) (Lepidoptera: Noctuidae) Nucleopolyhedrovirus (SpltNPV) in SpltNPV‐inoculated early sixth instars. Both the JH III and pyriproxyfen treatments sign ...

Abstract:
... Novel associations between exotic pathogens and native insects may result in major ecological and economical losses. In Europe, Monochamus galloprovincialis (Olivier) (Coleoptera: Cerambycidae) is the only known vector of the exotic pine wood nematode Bursaphelenchus xylophilus (Steiner & Buhrer) Nickle (Nematoda: Aphelenchoididae), the causal agent of pine wilt disease (PWD). Transportation of go ...

Brassica napus; Centaurea cyanus; adults; carbon; cotton; honeydew; isotope labeling; laboratory experimentation; natural enemies; nectar; nectaries; parasitic wasps; plant pests; pollen; stable isotopes; sugars
Abstract:
... Parasitic wasps are prominent natural enemies of crop pests. They usually feed on floral resources during the adult stage (nectar, pollen, or honeydew). Extrafloral nectar is an alternative source of sugar easily accessible to adult parasitoids. We developed an original method of nectar labelling based on the injection of labelled sugar solution into the plant stem in order to analyse the nectar u ...

Crotalaria juncea; Maize mosaic virus; Peregrinus maidis; Zea mays; autumn; corn; edge effects; field experimentation; habitat conservation; herbivores; intercropping; population density
Abstract:
... Habitat management (e.g., intercropping) may alter within‐field spatial distribution patterns of herbivores, from a typical pattern as observed in a monoculture, and may influence patterns of crop injury. Field trials were conducted to study the effect of intercropping maize, Zea mays L. (Poaceae), with sunn hemp, Crotalaria juncea L. (Fabaceae) strips on within‐field spatial distribution patterns ...

Abstract:
... Biological activity of the bacterium Bacillus thuringiensis Berliner (Bt) against insect pests is influenced by the host plants. To understand the underlying mechanism of variation in biological activity of Bt on host plants, we studied the effect of chemicals from the surface of chickpea (Cicer arietinum L., Fabaceae) leaves (ICCC 37 and ICC 506EB), sorghum [Sorghum bicolor (L.) Moench, Poaceae] ...

Abstract:
... Acromyrmex leaf‐cutting ants use the antibiotics produced by ectosymbionts (Actinobacteria) to suppress the growth of Escovopsis spp., which are the specialized parasites of attine fungus gardens. However, the spectrum of activity of these bacteria and their interactions with insect immune systems have not been thoroughly studied. The objective of this study was to evaluate whether the presence of ...

Abstract:
... Huanglongbing (HLB), also known as citrus greening, is currently the most destructive disease of citrus, responsible for huge economic losses in the world's major citrus production areas. The Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae), transmits ‘Candidatus Liberibacter asiaticus’ (Clas), the pathogen responsible to cause HLB. Understanding of vector, pathogen, and host ...
