Seasonal Occurrence, Development and Preference of Riptortus pedestris on Hairy Vetch

Abstract

The seasonal occurrence of Riptortus pedestris Fabricius was investigated using pheromone traps baited with its aggregation pheromone in the fields with various crop composition (mixture culture of barley and hairy vetch in Asan, Chungnam; monoculture of hairy vetch in Yuseung, Daejeon) from mid-May to mid-July of seed gathering season in 2010. The invasion of R. pedestris into the experimental fields began to increase rapidly from late-June in which period hairy vetch and barley reach the beginning of seed formation stage. After seed gathering season in mid-July, the invasion rate of R. pedestris decreased, and the activity was continually observed till early-November. In addition to dominant R. pedestris species, 33 species of hemiptera including Apolyaus watajii, Dolycoris baccarum, Adelphocoris suturalis, and Yemma exlis were collected, which indicated abundant species diversity in the hairy vetch fields. In the laboratory, R. pedestris did not developed successfully to adult stage on food sources of hairy vetch, with decreasing survival rate after 4th instar and the failure of emergence to adult stage. Also, R. pedestris showed higher preference on soybeans than hairy vetch. Consequently, hairy vetch may be not true host for the development and survival of R. pedestris. It is considered that R. pedestris is a temporary visitor at the season of seed formation in hairy vetch fields

Insecticidal Effect of Aggregation Pheromone Fish Net Trap using Residual Effect of Insecticides Against Bean Bug, Riptortus pedestris (Hemiptera: Alydidae)

“…하지만 톱다리개미허리노린재는 이동성이 강하 여 약제를 살포할 경우 인근포장이나 주변 잡초로 이동한 후 일정한 시간이 흐른 뒤 다시 이동해 오기 때문에 화학농 약을 살포하는 방법으로는 효과적인 방제를 하기 어렵다 (Paik et al, 2009;Seo et al, 2011 (Jones, 1988;Leal et al, 1995;Witzgall, 2001;, 나아가 좀 더 효과적인 예찰 및 방제방법으로 활용 될 수 있도록 집합페로몬의 조성비, 트랩의 종류 및 설치방법에 관한 연구도 이루어졌다 (Huh et al, 2008;Paik et al, 2009 재질별 처리약제의 잔효성 높은 살충활성을 보인 2종의 약제(bifenthrin, fenitrothion) 를 나무, 철, 플라스틱 재질에 처리하여 잔효성을 조사하였 다 (Fig. 2).…”

Influences of food sources on reproduction and aggregation pheromone production of Riptortus pedestris (Hemiptera: Alydidae) in its adult stage

“…Riptortus pedestris seems to be trivoltine in Korea. Adults of each generation occurred in early July to early August, mid August to late September and early October to mid November in southern Korea (Huh et al 2005a) and migrated seasonally among fruiting plants like hairy vetch, Vicia villosa, sweet persimmon and soybean (Chung et al 1995;Lee et al 2004;Seo et al 2011).…”
