Laju Parasitasi Parasitoid Anagrus sp. dan Oligosita sp. terhadap Telur Wereng Coklat setelah Aplikasi Insektisida di Pertanaman Padi
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.
