Abstract

Parasitism rate of Anagrus sp. and Oligosita sp. parasitoids to brown planthopper eggs after insecticides application in the rice field. The research wascarried out in Subang District, West Java in the wet season of 2013. The experiment used arandomized block design with 7 insecticide treatments and four replications. The treatmentswere rynaxypyr, fipronil, imidakhloprid, dinotifuran, pimetrozin, and BPMC compared withcontrol. The objective of the research was measuring parasitism rate of parasitoids to brownplant hopper (BPH) eggs after insecticides application. The results showed that rynaxypyr,dinotefuran, and imidacloprid quickly reduced the BPH population only in one day afterapplication (DAA), while fipronil, pimetrozin, and BPMC were rather slow because the BPHdeclined in 10 DAA. All insecticides were give a negative effect to Anagrus sp. and Oligositasp parasitoids, but the performance of those parasitoids back to normal in 10 DAA forAnagrus sp. and in 21 DAA for Oligosita sp. The parasitism rate of all parasitoids were give anegative value in 1-10 DAA. In 21 DAA the parasitism rate of Anagrus sp. increased infipronil, BPMC and dinotefuran treatment, but the parasitism rate of Oligosita sp. were still innegative value under the control treatment.

Abstract

The influence of meteorological factors on the rice pests flight that catched in the lighttraps of mercury lamp and CFL. Research was carried out in the 2013 at the experimentalgarden of Sukamandi, Indonesian Center for Rice Research (ICRR). Pests were catched in thelight traps of mercury lamp ML 160 watt and CFL 20 watt, while the meteorological data wascollected from a meteorological cage closed 200 m of the light trap. The objectives of thisresearch was to analyze the influence of meteorological factors on the pests flights as basicllyfor early warning system, forecasting and pests dispersal. The results showed that themeteorological factors such as evaporation, wind velocity, light intensity, air temperature,relative humidity, rainfall, and soil temperature at 0 cm were correlated one to anothers. Themeteorological factors had insignificant effect to pests flight of rice yellow stem borer, ricepink stem borer, rice black bug, and brown planthopper that catched in the lihgt trap ofmercury lamp and CFL. Evaporation and soil temperature at 0 cm had significant positiveinfluence while relative humidity had significant negative influence on the flight of leaf folderthat catched in the lihgt trap of mercury lamp. In the lihgt trap of CFL bulbs, the flight of leaffolder had significant positive influenced by air temperature and soil temperature at 0 cm,while had significant negative influenced by relative humidity and rainfall.
