Effect of Color Sticky Traps on the Population of Major Pests of Improved Pigeon Pea (Cajanus Cajan (L) Millsp) Cultivar and Its Yield in Owerri, Imo State, Nigeria

Abstract

Study on the management of major insect of pigeonpea with colored sticky traps was conducted at the Department of Crop Science and Technology Teaching and Research Farm, Federal University of Technology Owerri, Imo State, in 2013.  The experiment was laid out using randomized complete block design (RCBD) with six treatments comprising different colors of sticky traps, namely blue, black, white, red, yellow sticky traps and the uncolored sticky trap as a check (control).  Results revealed that yellow sticky traps attracted and trapped the highest number of insect pest, and also had the highest pod yield of 186.90 kg ha-¹ and seed yield of 163.80 kg ha-¹ compared to other treatments. To produce organic pigeonpea seeds free from chemical metabolites, the use of yellow sticky traps to manage the population of insect pests in the farmers' field can be incorporated into pigeonpea IPM control strategy in, Nigeria.
