Safety Selected Insecticides to Predators and Egg Parasitoids of Planthoppers in Rice Ecosystem
Journal Title: American journal of Engineering Research - Year 2017, Vol 6, Issue 6
Abstract
The research safety selected insecticides to predators and egg parasitoids of planthoppers in rice ecosystem was carried out in the wet season of 2014 at Subang District. The several insecticides of mixture chlorantranilprole + thiamethoxam, pymetrozine, emamectin benzoate and deltamethrin were sprayed on rice plots at 20 and 35 days after transplanted (dat). Observation to planthoppers and predators by visual counting, while observation to egg parasitoids through parasitism by BPH eggs trap. The result showed that pimetrozine had reduced BPH population, followed by chlorantranilprole + thiamethoxam. In the other hand chlorantranilprole + thiamethoxam, pimetrozine and deltamethrin had reduced WBPH population. Insecticides of chlorantranilprole + thiamethoxam, pymetrozine, emamectin benzoate and deltamethrin highly safety against L. pseudoannulata, P. fuscipes, and Coccinella sp., but those insecticides moderately safety to O. nigrofasciata and spiders (without L. pseudoannulata). Insecticides of chlorantranilprole + thiamethoxam, emamectin benzoate and deltamethrin moderately safety against C. lividipennis, but pymetrozine moderately unsafety to this predator. Chlorantranilprole + thiamethoxam were moderately unsafety to parasitism of eggs parasitoids Anagrus sp., but was moderately safety to parasitism of eggs parasitoids Oligosita sp.. Pymetrozine and emamectin benzoate were moderately safety to Anagrus sp., but moderately unsafety to Oligosita sp.
