TOKSISITAS SEKRESI PERTAHANAN DIRI RAYAP TANAH COPTOTERMES CURVIGNATHUS HOLMGREN TERHADAP SEMUT ODONTOPONERA DENTICULATA
ABSTRACT: Soldier from
subterranean termites Coptotermes curvignathus eject a poison secretions as a
defensive secretions to overcome their enemy. This research aimed to evaluation
the toxicity of soldier defensive secretions extract in aquabidestilata,
ethanol, ethyl acetate and n-hexane solutions against Odontoponera denticulata
ants. Filter paper with 200 µl extract were exposure to ants for 14 day. The
first time ants mortality and time for all ants mortality were recorded.
Result of the research showed that the first time ants mortality was on ethanol
extract (15 minutes after exposure), then followed on ethyl acetate extract, n-hexane
extract and aquabidestilata extract for 30, 35 and 40 minutes respectively.The
faster time for all ants mortality was on ethanol extract (54 hour), then
followed by ethyl acetate extract,
n-hexane extract and aquabidestilata extract for 74, 79 and 82 hour
respectively. GCMS analysis showed that the bioactive compound on ethanol
extract were pentadecanal and tetradecanal.
