Abstract

Research on the effect of host larval stage on survivorship of the parasitoid E. argenteopilosus was conducted under laboratory conditions. Survivorship was studied by using S. litura larval with different stage (1st, 2nd, 3rd, and 4th instars). Result of the research indicated that development rate of the parasitoid E. argenteopilosus is faster when reared on 3rd instar larvae. The higher the level of host-instar larvae, shorter time was needed to complete the parasitoid’s life cycle. Only 4.67% of the larvae completed its development to pupal stage, and only 1% reached adulthood, with males being the dominant of the emerging adults.

Abstract

The lady beetle, Menochilus sexmaculatus is one of the biological control agents that can be used to control aphids. Presently, there is a lack of information about the effectiveness of this beetle to control aphids. The objective of this research was to study the functional response of M. sexmaculatus on Aphis gossypii at different ages of plants. All preys were exposed to one M. sexmaculatus adult for an hour at five different densities of aphids (10, 20, 30, 40, and 50 individuals) is four different ages of chilli plants (2,4,6, and 8 weeks). Data were analyzed by ANOVA and logistic regression to determine the type of functional response. The results showed that the ability of M. sexmaculatus to prey was not significant at 2 to 4 and 6 to 8 weeks old chilli plants. At 2 week old chilli plants M. sexmaculatus showed type I of functional response, while at 4, 6 and 8 weeks the functional response were type III.

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.
