Abundance of predators in country bean field during summer season
Abstract
The study was conducted at the experimental field of Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh during March to June 2009 in order to know the abundance of biological control agents (predators) in country bean ecosystem. During the study period the predators, black ant (Formicidae), lady bird beetle (Coccinellidae), Stink bug (Pentatomidae), Damsel fly (Coenagrionidae) and spider was found considerably. At the vegetative stage black ant (Formicidae) was highly abundant followed by lady bird beetle and spider. At the reproductive stage lady bird beetle, black ant and pentatomid bug found abundantly.
