Abstract

Habitat conditions around cocoa plantations which include canopy cover and lower vegetation (weeds) as well as the presence of mealybugs trophobiont (Planococcus sp.) can affect the diversity and abundance of ants. The objective of this research was to study the diversity and abundance of ants in cocoa plantations and to study the effect of habitat conditions and the presence of trophobiont (Planococcus sp.) on species richness and ant abundance. The research was carried out in 12 locations spread across five districts in East Java. Ant samples were collected by tuna bait and direct collection. The results obtained 5,475 individuals and 8 species of ants. The most dominant ants and found in all areas were Dolichoderus thoracicus (Smith) and Technomyrmex albipes (Smith). Based on the regression analysis, there is a relationship between canopy cover and vegetation diversity with ant species, but not with abundance, meanwhile the presence of trophobiont shows a positive correlation with ant abundance. The habitat conditions for cocoa cultivation and the presence of trophobiont affect the diversity and abundance of ants in cocoa plantations.

Abstract

The study aimed to determine the reproductive ability of fruit flies B. carambolae treated with B. bassiana and Lufenuron. This study is conducted at the Laboratory of Pest. Department of Plant Pests and Diseases, Faculty of Agriculture, University of Brawijaya, Malang. This study used a completely randomized design with nine treatment and three replications. The study was trying to evaluate the effect of B. bassiana and Lufenuron on the reproduction capacity of B. carambolae. Results showed that adults of B. carambolae to applied combination of B. bassiana and Lufenuron immediately after coming out of the pupae until day eighth have the average number of eggs laid is 7.69%, a decrease of fecundity 92.40%, egg fertility by 61.38% and 95.24% decrease of reproduction. Adults of B. carambolae applied of B. bassiana and Lufenuron on day eighth until day sixteenth (for 8 days), show a decrease in the number of eggs laid by 13.63%, the decrease of fecundity 88.50%, egg fertility by 50.16% and decrease of reproduction by 93.12%.Keywords: Bactrocera carambolae, Beauveria bassiana, Lufenuron.

Abstract

Rhyzopertha dominica is a polyphagous stored pest to many grains including rice. R. dominica can easily spread from one place to another to infest stored products. The aim of this research was to know the influence of three grains types with different weight to R. dominica growth, development, net reproduction rate and gross reproduction rate on red, black and white rice. The research was conducted in Pest Laboratory, Department of Plant Pests and Diseases, Faculty of Agriculture, University of Brawijaya Malang. The research result showed that there was an interaction among three grains types with different weight to the number of R. dominica larval, pupal, and newly adult emerged, while the number of eggs, weight of newly adult emerged, the reduction percentage of grain and phase of the egg, larval, pupal and the life cycle period of R. dominica were affected by different grains types factor. The R0value showed that on the next generation, number of female was increase 1.25 times from the previous generation on white rice, while on red and black rice the population was increase up to 2.63 and 2.49 times from the previous generation.Keywords: Growth and Development, Reproduction Rate, Rice, Rhyzopertha dominica.
