Abstract

The study aims to determine the types of insects that attack teak plants, diagnose the symptoms of attack and estimate the magnitude and intensity of attacks caused by teak pest attacks. The results found two types of pests that attack teak stands namely Woodhoppers (Valanga nigricornis) and Caterpillars (Hyblaea puera) with moderate damage intensity. Wooden Grasshopper (Valanga nigricornis) measuring 45 - 55 mm (male) and 1575 mm (female), has a head, chest, thorax and abdomen, yellowish brown with a dark blue hue on the wings. The rear wing is visible when flying and is red. Teak caterpillars (Hyblaea puera) are found to be brown with a pair of small yellow stripes on each side, and between two lines are dark brown with a length of 3.5 cm, while the cocoon is dark brownish black, with an average length of 1.4-1, 9 cm, and an average weight of 0.7-1.3 mg. Valanga nigricornis attack area of 29.58% belong to the category of moderate attack and Hyblaea puera of 23.41% belonging to the category of mild attack

Abstract

The aim of this study was to determine the effect of  botanical biopesticide extracts and concentrations on soil termite mortality of Coptotermes curvignathus, Holmgren. This research was an experimental study using a fully randomized design (CRD) consisting of 2 3-level treatments that were repeated three times. Treatment was a type of botanical biopesticide consisting of three levels, namely are A1 (papaya leaf), A2 (soursop leaf), A3 (lemongrass leaf). In comparison, the concentration of botanical biopesticide consists of three levels: B0 (without or as a control biopesticide), B1 (500 grams), B2 (1,000 grams) and B3 (1,500 grams) which have been repeated three times. The data that had been tabulated was then analyzed using Variant Analysis, and if there was any influence, the difference test was continued at 5 % and %. The results showed that the treatment of papaya leaf biopesticides (A1) had a faster reaction to the death rate of termite (95.6  % ) and the lowest was the death rate of soursop leaf (A2) termite (90.7 % ). In comparison, lemongrass (A3) caused soil termite mortality (94.1 %). In addition , treatment of biopesticide concentrations of B3 (1,500 grams) resulted in higher termite mortality of 96.67 %. compared to B2 (1,000 grams) with mortality of 94.07 % and B1 (500 grams) with mortality of 89.62 %.Whereas, for the interaction between the two treatments, the highest level of termite mortality was papaya leaf biopesticide with a concentration of 1,500 grams (A1B3) and termite mortality was 100 %.
