Biological Control Based IPM of Insect Pests on Sweet Pepper in Greenhouse in the Summer

Abstract

Biological-control-based-integrated-pest-management of major pests occurring on sweet pepper in greenhouse during summer season was tried. As many as 2.1 Orius laevigatus per m 2 were released in two times on June 6 and 19, and the population of thrips was kept under control and accordingly the damage was negligible throughout the season. To control aphids, a total of 0.8 Aphidius colemani per m 2 were released in four times, 0.2 of them at a time, flonicamid on May 14 and July 18 and pymetrozine on June 14 and September 4 were sprayed on the spots of high aphid occurrence to reduce the release of the wasp, and the density of aphids was kept under control. Whitefly was controlled successfully by releasing a total of 343.4 Amblyseius swirski per m 2 in nine times, 38.1 of them at a time, from May 9 until November 12 and dinotefuran was sprayed on November 12 when the density of whitefly increased up to 200 per trap. Tetranichus kanzawai was controlled by both Phytoseiulus persimilis which was released a total of 44.4 per m 2 in five times 8.9 of them at a time from May 23 to September 10, and the A. swirski which was released for the control of whitefly. KEY WORDS : Sweet pepper, Biological control based IPM, Major pests, Summer season culture 초 록 : 여름작기 파프리카의 주요해충에 대한 생물적방제 기반 종합적관리를 시도하였다. 총채벌레류 방제를 위해서 m 2 당 총 2.1마리의 미끌애꽃노린재(Orius laevigatus)를 6월 6일과 19일 두 번 방사하여 작기 동안 피해가 없었다. 진딧물 방제를 위해서는 m 2 당 총 0.8마리의 콜레마니진디벌(Aphidius colemani) 을 4회에 걸쳐 방사하고, 진딧물 밀도가 높은 지점에 국부적으로 플로니카미드와 피메트로진을 5월 14일과 7월 18일, 6월 14일과 9월 4일에 각각 2회씩 살포하여 콜레마니진디벌 사용량을 줄었다. 담배가루이 (Bemisia tabaci)에 대해서는 지중해이리응애(Amblyseius swirskii)를 5월 9일부터 한번에 m 2 당 38.1마리씩 9회에 걸쳐 총 343.4마리를 방사하였으며, 담배가루이 밀도가 트랩 당 200마리에 달했던 11월12일에 천적으로 방제가 어려워 디노테푸란을 1회 살포하여 방제하였다. 차응애(Tetranichus kanzawai)는 칠레이 리응애(Phytoseiulus persimilis)를 5월 23일부터 9월 10일까지 5회에 걸쳐 한 번에 m 2 당 8.9마리씩 총 44.4마리를 방사하였으며, 담배가루이 천적인 지중해이리응애가 차응애의 알과 약충을 포식함으로서 두 종의 천적에 의한 차응애 밀도가 억제되었다.

A study on the proliferation of Myzus persicae (sulzer) during the winter season for year-round production within a smart farm facility

“…Crop damage caused by pests is gradually becoming more severe worldwide [4]. Major insect pests are Myzus persicae and Aphis gossypii (Hemiptera: Aphididae), Tetranychus urticae and T. kanzawai (Trombidiformes: Tetranychidae), Polyphagotarsonemus latus (Trombidiformes: Tarsonemidae), Liriomyza trifolii (Diptera: Agromyzidae), Palpita indica (Lepidoptera: Pyralidae), Frankliniella intonsa and F. occidentalis (Thysanoptera: Thripidae), and Bemisia tabaci (Hemiptera: Aleyrodidae) [5][6][7][8][9][10].…”

Simultaneous determination of flonicamid, imidacloprid, and its metabolites in paprika by QuEChERS and tandem mass spectrometry

“…This insecticide shows selective activity against similar insecticides that show cross-resistance. Because flonicamid's mode of action does not involve the nicotinic acetylcholine receptor, and because flonicamid inhibits the feeding behavior of aphids, the use of this pesticide minimizes both the toxicity to beneficial arthropods and the development of cross-resistance in insects (Morita et al 2007;Choi et al 2009;Jansen et al 2011).…”
