摘要: In laboratory trials, mating behaviour of males Lobesia botrana Den. and Schiff. (Lep., Tortricidae) was investigated after treatment with an electrostatically chargeable powder, EntostatTM. Male moths were powdered either blank Entostat or containing sex pheromone. Significantly more adhered to L. when pheromone added the powder compared Entostat. Powdering male Entostat, without pheromone, caused a significant reduction in antennal response antennae placed 2 cm away downwind direction, while there little effect 25–100 from EAG direction. flight study, powdering increase time before initiation proportion making contact calling females untreated males. experiment Petri dishes (to minimize required search locate female), significantly fewer mated successfully (based on dissection bursa copulatrix) had been treated pheromone-loaded powder. Overall, considerable suppression various levels, these suppressing effects increased adding
