Efficacy of teak and pine litter extract with several solvent against wood termites (Cryptotermes cynocephalus light)

Abstract

Termites are social insects that play an important role in the decomposition and nutrient turnover. In addition, termites are also categorized as pests that eat wood or materials composed of cellulose. Some form of control one of them has been done by making biopesticides. Various types of raw materials have been used from agricultural, plantation and forestry crop groups. Termite mortality is one indicator to determine extract bioactivity by calculating the percentage of the number of termites that died after being given treatment at a certain time. Compound content bioactive substances such as alkaloids, phenolics and other chemicals that can be used to kill and controlling insects in the environment. This study examines the effectiveness teak litter extract and pine litter extract with various solvents against wood termites through experimental research activities in the laboratory. The content of teak litter extract levels and pine litter obtained by 2.5%. Based on the termite mortality value test, the highest toxicity in the ethyl acetate extract, which is at week 3, it has reached 100% at a concentration of 1% which is. In addition, based on testing the retention value of the test paper, The highest percentage of weight loss was in the control, followed by the n-hexane fraction 49.55%. Whereas in testing the level of termite consumption, the highest percentage was in the aquades fraction.
