Field Studies of a Male-Released Aggregation Pheromone in Pissodes nemorensis12

Abstract

Response of the deodar weevil, Pissodes nemorensis Germar (Coleoptera: Curculionidae), to traps containing slash pine bolts and males, females, males with females, or no adults was studied in northern Florida in each of two studies. Significantly more weevils were caught at traps containing males than at any other treatment. Approximately equal numbers of male and female weevils responded to all treatments in both studies. Peak response to male-baited traps was observed in November, and a small peak was observed in February.
