Abstract

Aphid is a sucking insect as a pest and vector of virus diseases plants. The aphids presence on plants are often accompanied by ants that symbiotic on aphid’s colony. Mutualism symbiosis between ants and aphids can hinder natural enemies especially parasitoids to parasitizing aphids. This study aims to explore parasitoid and ant species associated with aphids and determine the level of parasitoid parasitization. The survey was conducted on agricultural crops and weeds in West Java area. Samples were taken by purposive sampling looking at the aphid presence, ant, and mummified colonies. Aphid’s identification was carried out at Insect Biosystematics Laboratory, Department of Plant Protection IPB, whileparasitoid and ant identification was carried out at Entomology Laboratory of Zoology LIPI. The identification results obtained four species of Hymenoptera parasitoid, i.e Adialythus ambiguus, Aphidius matricariae, Praon absinthi (Braconidae) and Psyllaephagus pilossus (Encyrtidae) and eight species of ants of Formicidae family, i.e Dolichoderus sp, Dolichoderus thoracicus, Monomorium destructor, Monomorium floricola, Myrmicaria brunnea, Pheidole javana, Polyrhachis dives, and Technomyrmex albipes. The dominant parasitoid species found was A. matricariae, but the highest level of parasitization was P. pilossus (78%), parasites Rhopalosiphum padi in rice plants. Basic information on the types of ants and parasitoid insects associated with aphids can be used in the development of aphids integrated pest management strategies.

Abstract

The papaya mealybug (Paracoccus marginatus) Williams & Granara de Wilink (Hemiptera: Pseudococcidae) is a main pest of papaya plants. Attacks by these pests can cause plants failed to produce the fruit and even to death. The usual control technique used by farmers is the use of synthetic pesticides that have a negative impact on human health and the environment. The alternative to control using botanical insecticides is a good solution to control the population of P. marginatus. The purpose of this study is to know the effect of neem seed oil formulation and bitung to know which treatments with concentrations are most effective in reducing the population density of papaya mealybug pests. The experiment took place in Rejasari Village, Langensari Subdistrict, Banjar City, West Java, from March 2021 to July 2021. Experiment using the Randomized Block Design consisted of ten treatments with three replications. The results were obtained that a formulation of bitung 3% could suppress the densities of papaya mealybug ( P. marginatus) populations at 65%. The average weight of the resulting papaya contained a 3% formulation of bitung found at 9.8 kg/tree. botanical pesticides of bitung oil 3% can be used instead of synthetic pesticides to control the population of P.marginatus.
