Male moths discriminate conspecific female-emitted sex pheromones. Although the chemical components of pheromones have been identified in more than 500 moth species, only three Bombyx mori and Heliothis virescens had their receptors identified. Here we report identification for main sex-pheromone Plutella xylostella, Mythimna separata Diaphania indica. We cloned putative receptor genes PxOR1, MsOR1 DiOR1 from P. M. D. indica, respectively. Each was exclusively expressed with an Or83b...
Abstract Olfactory and visual cues were shown to mediate short‐distance orientation in Anoplophora malasiaca (Thomson) (Coleoptera: Cerambycidae). In a laboratory test, more than 80% (n = 42) of males walked straight upward when presented with an untreated surface 75° slope. When freshly killed female was fixed at short distance (10 cm ahead 5 left/right) from the starting point, 50% 30) oriented toward before direct contact. Similar behavioural responses observed extract directly applied...
Abstract Two active fractions were found during the isolation of contact sex pheromone female elytra white‐spotted longicorn beetle, Anoplophora malasiaca (Thomson) (Coleoptera: Cerambycidae), in addition to fraction hydrocarbons that had previously been identified. One was essential evoke a series precopulatory behaviors males toward glass dummy when coated together with hydrocarbon blend. The other enhanced this activity added mixture. From latter synergistic fraction, we isolated five...
Abstract Two chemical compounds eliciting prey‐locating behavior of the predatory stink bug, Eocanthecona furcellata , were isolated from solvent extracts Spodoptera litura larvae and identified. A hexane eluted fraction silica gel chromatography S. was attractive to E. nymphs when assayed with a linear track olfactometer. The found contain n ‐pentadecane (2500 ng/larva), n‐tetracosane (54 ‐heptadecane (41 ‐heptacosane (61 ‐nonacosane (147 ‐hentriacontane (200 ng/larva) squalene (323...
