Abstract

Entomopathogen is one of the biological agents that infects the insects and can damage the body's metabolic system of insects. This objective of the study were to determine the entomopathogenic activity of S. marcescens on mortality of coconut leaf beetles larvae ( B. longissima ), and the time needed to reach LT 50 . The study used an experimental method with 6 treatments of varying S.marcescens volumes, consisting of A (distilled water as a control), B (5 ml), C (7.5 ml), D (10 ml), E (12.5 ml), and F (15 ml) with 4 replications. The data were analyzed using ANOVA and Probit LT50 test. The results showed that the volume of S.marcescens had an effect on mortality of coconut leaf beetle B. longissimi larvae. The best mortality rate at treatment E is 78% with the value of LT50 in treatment F is 42.15 hours. S.marcescens has entomopathogenic activity in coconut leaf beetles ( B. longissima ) Gestro larvae

昆虫病原体Serratia marcescens Bizio对椰子幼虫(Brontispa longissima) Gestro的灭绝性活动

昆虫病原体是一种感染昆虫并破坏昆虫体内代谢系统的生物制剂。本研究旨在测定粘质葡萄球菌对椰叶甲虫幼虫(B. longissima)的致病性及其达到l50所需的时间。本研究采用6种处理方法，分别为A(蒸馏水为对照)、B (5 ml)、C (7.5 ml)、D (10 ml)、E (12.5 ml)、F (15 ml)，共4个重复。数据分析采用方差分析和Probit LT50检验。结果表明，粘多糖的数量对长叶椰子虫幼虫的死亡率有影响。治疗E的最佳死亡率为78%，治疗F的LT50值为42.15 h。粘多糖在椰叶甲虫幼虫中具有昆虫病原活性
