Abstract

The present study was conducted during March to July 2021 in the experimental field of the Department of Entomology of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur to evaluate the effect of some biorational insecticides on pod borer infestation in yard long bean. The study was laid out by Randomized Complete Block Design (RCBD) with 3 replications. The treatment comprised Vermitec 1.8 EC (Abamectin) @ 1.0 ml/L, Tracer 45 SC (Spinosad) @ 0.4 g/L, Bio-Action 1.5 SL (Matrine) @ 1.5 ml/L of water, Ecomec 1.8 EC (Azadiractin) @ 1.5 ml/L and Phytoclean (Potassium salt of fatty acid 40%) @ 1.5 ml/L of water at 15 days interval along with an untreated control for comparison. The study revealed that the lowest rate of inflorescence infestation, the highest reduction of flower shedding, lowest rate of pod infestation by pod borer as well as the highest fruit sets and marketable yield (10.7±0.3 MT/ha) was recorded with the bio-rational management approach comprising 3 sprays of Tracer 45 SC (Spinosad) @ 0.4 g/L of water

不同生物理性杀虫剂对豆角螟侵染的影响

本研究于2021年3月至7月在加济普尔邦班班杜谢赫·穆吉布·拉赫曼农业大学昆虫学系(BSMRAU)的试验田进行，以评估几种生物杀虫剂对长豇豆荚虫侵染的影响。本研究采用随机完全区组设计(RCBD)，共3个重复。处理包括Vermitec 1.8 EC(阿维菌素)@ 1.0 ml/L, Tracer 45 SC (Spinosad) @ 0.4 g/L, Bio-Action 1.5 SL(苦参碱)@ 1.5 ml/L水，Ecomec 1.8 EC (Azadiractin) @ 1.5 ml/L水和Phytoclean(脂肪酸钾盐40%)@ 1.5 ml/L水，间隔15天，并与未经处理的对照进行比较。研究结果表明，以0.4 g/L水喷施示踪剂45 SC (Spinosad) 3次的生物合理管理方法，侵染花序率最低，脱花率最高，豆荚螟侵染荚果率最低，坐果数和可售产量最高(10.7±0.3 MT/ha)

期刊介绍： The Open Ecology Journal is an open access online journal which embraces the trans-disciplinary nature of ecology, seeking to publish original research articles, reviews, letters and guest edited single topic issues representing important scientific progress from all areas of ecology and its linkages to other fields. The journal also focuses on the basic principles of the natural environment and its conservation. Contributions may be based on any taxa, natural or artificial environments, biodiversity, spatial scales, temporal scales, and methods that advance this multi-faceted and dynamic science. The Open Ecology Journal also considers empirical and theoretical studies that promote the construction of a broadly applicable conceptual framework or that present rigorous tests or novel applications of ecological theory.
