Abstract

The objective of this research was to compare the diversity of insects in chili plant agroecosystem treated with synthetic pesticide versus that treated with biopesticide (venom of spider Nephila sp.) Two plots of chili pepper plants, each sized 600 m2, located at Ciwidey area Bandung –West Java, were taken as the sample plots. The first plot was weekly treated with profenofos insecticide (50% active ingredient, a.i.) while the second plot was treated with biopesticide (70% a.i. spider venom extracted from Nephila sp.), each at 35 ml/17 L rate of spray solution. Sweep net was used to sample insects along two transects in each plot. Result showed that 14 families of 8 insect orders were found in pesticide-treated plot while 15 families of 9 orders were found in biopesticide-treated plot. The evenness index and diversity index of insects in plot treated with biopesticide were relatively higher than those in pesticide-treated plot. In contrast, dominance index in biopesticide plot was lower than that in synthetic pesticide plot. Thrips sp.(Thysanoptera: Thripidae) was found to be the most dominant species in both plots.

Abstract

The effect of SlNPV infection on  peritrophic membrane  of Spodoptera litura has been carried out. The damage of histological structure caused by SlNPV (0, 315, 390, 465, 540 and 615 PIB/ml) was investigated after 0, 12, 24 ,72 and 96 hours post infection. The histological material was prepared by using parafin method after fixation with Bouin Solution, then sliced into 7 mm and stained with Hematoxilin-Eosin.   The descriptive obsevation on structural intact of peritrophic membrane histology caused by SlNPV infection shows a tendency to decrease, while in control, there was no damage at all.  The longer the exposition of virion in the midgut lumen the more damage on peritrophic membrane occurred. The severest damage occurred 96 hour after infection. The result prove that haNPV virion can destroy histological structure of midgut
