Abstract

Research of the effect of adult feeding to longevity and fecundity of parasitoid Eriborus argenteopilosus Cameron (Hymenoptera: Ichneumonidae) was conducted under laboratory conditions. Fitness was studied by feeding adults Eriborus with different types of food ( 10% honey, 10% yeast, aquadest). Results of the research indicated that fitness and longevity were highest when Eriborus was fed with 10% honey. There is a positive correlation between size and fecundity, suggesting certain measures of body length can be used as indicators of fitness.

Abstract

This research purposed to study biology of Helopeltis sp. on cocoa and cucumber fruits. Research was done in insect bioecology laboratory using direct observation with 10 replications for each fruit. Parameter observed were copulation (hours), preoviposition time (days), number of eggs, nymphals, and adult periods (days), Oviposition time (days), and post oviposition time (days). The data obtained were analyzed descriptively and compared with t-test. Result of this research showed that Helopeltis sp. could thrive in cacao and cucumber fruits. Adult of Helopeltis sp. longevity in cacao fruits was 16 days and in cucumber fruits was 13 days. The number of eggs product average 10-10.9 eggs/female.

Abstract

Penelitian ini bertujuan untuk mempelajari karakter fisiologi isolat B. bassiana yang berasal dari berbagai inang dan virulensinya terhadap Spodoptera litura. Lima isolat B. bassiana yang diuji diisolasi dari hama Leptocorisa oratorius (F.) dan Hypothenemus hampei (Ferr.), rizosfer tanaman bawang daun buah kakao dan batang gandum. Karakter fisiologi yang diamati adalah daya kecambah konidia, pertumbuhan koloni, dan sporulasi, Cendawan diperbanyak pada media SDAY dan uji virulensi dilakukan terhadap larva instar II S. litura. Hasil penelitian menunjukkan bahwa daya kecambah konidia, pertumbuhan koloni dan sporulasi bervariasi antar isolat. Isolat B. bassiana yang diisolasi dari L. oratorius dan buah kakao memiliki karakter fisiologi yang lebih baik dibandingkan dengan isolat lain. Kedua isolat ini juga lebih virulen terhadap larva instar II S. litura dengan mortalitas sebesar 80 – 81,67%.
