Olfactory Cue

The sexual response of male Schizocosa crassipalpis (Emerton), S. avida (Walckenaer), Pardosa moesta Banks, and P. saxatilis (Hentz) to filter paper discs previously exposed to females was studied in the laboratory. Evidence indicates that the females secrete a nonvolatile substance which the males receive through contact chemoreception and which excites them sexually. Attempts to demonstrate an olfactory cue in the sexual response were unsuccessful. The substance was found to be species specific except in S. crassipalpis. It was produced by adult females regardless of age or mating history. Male response was similarly not affected. The substance was active for about 4 weeks. It was labile to treatment with ether or benzene and could not be extracted with either solvent. The sites of its secretion and perception have not been ascertained.

Longicorn Beetle

The white-spotted longicorn beetle, Anoplophora malasiaca, is one of the most destructive pests of horticultural crops and street trees. Effective controls are needed because the effect of marketed insecticides is limited. Entomopathogenic fungi offer a solution, and improving the rate of infection would be a breakthrough in this beetle’s control. The combination of pathogenic fungi and the beetle’s contact sex pheromone was suggested. The surface of the female body is covered with contact sex pheromone, which elicit male mating behavior. To develop a method for the practical control of this beetle, we evaluated the arrestant activity of female extract containing contact pheromone coated on a black glass model. Males presented with a coated model held on for 5 h (mean) during an 8-h experiment. In contrast, males presented with a control model held on for <0.3 h. Males that held onto coated models attached to fabric impregnated with conidia of the fungus Beauveria brongniartii picked up much conidia, which they then passed on to females during mating.
