چکیده

Abstract Background The rugose spiraling whitefly (RSW), Aleurodicus rugioperculatus Martin (Hemiptera: Aleyrodidae), an exotic polyphagous pest and its infestation was documented on coconut ( Cocos nucifera L.) for the first time in India during 2016. RSW has attained a serious many economically important crop plants due to damage severity rapid spread across country short span of time. Hence, attempt made evaluate efficiency entomopathogenic fungus (EPF), Isaria fumosorosea alone as well combination with reduced dose few insecticides against devise sustainable integrated management module. Thirty-two randomly selected RSW-infested palms were labelled, eight treatments four replications used randomized complete block design summer months (April May) 2021. Two sprays performed at 15-day intervals, rate 5 L/palm, observations infestation/palm (%), intensity (%) mean live colonies recorded. Results results revealed that I. (ICAR-NBAIR Pfu-5) @ ml/l + profenophos 50 EC 2 spray significantly per cent (82.97%), (80.49%) (79.68%) followed by buprofezin 25% SC 1.25 (79.35%), (74.79%) (74.20%) over untreated control. A (5 ml/l) (2 twice interval 15 days found effective reducing population coconut. Conclusions present study concludes can be controlled effectively novel which showed better toxicity, ovicidal action preserve natural enemies environmental load chemical pesticides.
