Abstract

Soybean gall midge, Resseliella maxima Gagné (Diptera: Cecidomyiidae), is a pest of soybean that causes significant yield losses. Pterostichus melanarius (Illiger) (Coleoptera: Carabidae) has been reported as the most abundant predator of R. maxima in the field and feeds on R. maxima in the laboratory. Understanding the feeding behaviors of P. melanarius is crucial to determining the potential of this predator as a biological control agent for R. maxima. We conducted laboratory-based experiments on the functional response and prey preference of P. melanarius. The functional response study was performed with densities of R. maxima ranging from 1 to 60 larvae per Petri dish. Pterostichus melanarius exhibited a Type I (i.e., linear) functional response after 1 hr with an estimated handling time (T_h) and attack rate (a) of 0.0054 ± 0.0055 (SE) and 0.7076 ± 0.1339 (SE), respectively. The prey preference study was performed with three different ratios of R. maxima larvae and soybean aphids, Aphis glycines Matsumura (Hemiptera: Aphididae) offered as prey. Results indicated that P. melanarius consumed greater ratios of R. maxima to A. glycines than were offered. Overall, the results show that P. melanarius is a voracious predator of R. maxima and prefers R. maxima over A. glycines. These feeding behaviors of P. melanarius suggest promise for biological control of R. maxima by this predator.

期刊介绍： Biological control is an environmentally sound and effective means of reducing or mitigating pests and pest effects through the use of natural enemies. The aim of Biological Control is to promote this science and technology through publication of original research articles and reviews of research and theory. The journal devotes a section to reports on biotechnologies dealing with the elucidation and use of genes or gene products for the enhancement of biological control agents. The journal encompasses biological control of viral, microbial, nematode, insect, mite, weed, and vertebrate pests in agriculture, aquatic, forest, natural resource, stored product, and urban environments. Biological control of arthropod pests of human and domestic animals is also included. Ecological, molecular, and biotechnological approaches to the understanding of biological control are welcome.
