Abstract

The oriental tobacco budworm, Helicoverpa assulta (Guenee) is a major pest of red pepper in Korea. Insecticide spray is a prevalent control tactic in most farms, but an effective control is difficult because the larvae are protected inside the fruit. Objective of this study was to investigate the seasonal occurrence of the male moths using pheromone trap and to evaluate the control efficacy of insecticide applications based on the trap catch data at red pepper fields in Suwon. The results of pheromone trap catch during three years showed that the moth flight activity occurred from late May to early October. Peak periods of the adult flight, which are indicators of each generation, occurred in late June, late July-early August, and late August-early September. Trap catches during the overwintering and first adult generation were closely linked with subsequent damage. Although the trap catch during the second generation was higher than the previous generations, damage level caused by this generation larvae was low. Experiment results revealed that fruit damage by H. assulta could be effectively reduced by five sprays of insecticides based on the trap catch data throughout the season.

고추의 주요 해충인 담배나방은 유충이 과실 속에서 가해하기 때문에 방제가 어려운 해충이다. 수원지역의 고추 포장에서 페로몬 트랩을 이용하여 성충의 발생소장을 조사한 결과 전체 발생기간은 5월 하순부터 10월 상순까지였으며 각 세대의 발생 최성기는 6월 하순, 7월 하순 8월 상순, 8월 하순 9월 상순이었다. 월동세대와 1세대 성충 발생기간 중에 트랩유인 수준은 그 이후에 발생하는 유충에 의한 과실의 피해정도를 잘 반영하였다. 그러나 고추 생육후기에 발생하는 2세대의 경우 트랩에 유인되는 성충의 수는 매우 많았으나 유충에 의한 피해율은 그다지 높지 않았다. 페로몬 트랩으로 조사된 세대별 성충 발생시기에 관한 정보를 토대로 약제방제 시험을 수행한 결과, 각 세대별 성충 발생 최성기를 중심으로 연 5회에 걸쳐 살충제를 살포하면 유충에 의한 과실 피해를 효과적으로 줄일 수 있는 것으로 조사되었다.
