Abstract

Okra is the most familiar and widely known for its edible fruits. Several sucking and chewing insect species infest okra crop in the field. The field study was conducted to determine the attraction of four different colored traps to aphids in okra field. It is hoped that the information from this study will be able to help in the monitoring and management of these pests, as well as enhance integrated pest management programs in Pakistan and other countries with similar ecological conditions. The okra seeds were sown on both sides of well-prepared ridges. Red, blue, green and white colored sheets of sticky paper placed in the field with the help of bamboo stakes. The aphids were counted on sticky cards after 24 hours of their application. Aphid population appeared on okra from first week of observation and remained until last observation. Red colored attract maximum number of aphids, followed by green, white and blue. Plant vegetative and reproductive growth increased regularly with increase of crop age.

Highlights

Okra, Abelmoschus esculentus L. (Moench) is among the most familiar and widely known species of the family Malvaceae (Naveed et al, 2009)
Thrips tabaci, Amrasca devastans, Aphis gossypii, Earias spp and Helicoverpa armigera are considered as most destructive insect species, which attacking crop from sowing till the harvest (Shabozoi et al 2011, Sahito et al, 2012, Aziz, 2012)
It is hoped that the information from this study will be able to help in the monitoring and management of these pests, as well as enhance integrated pest management programs in Pakistan and other countries with similar ecological conditions

Summary

Introduction

Abelmoschus esculentus L. (Moench) is among the most familiar and widely known species of the family Malvaceae (Naveed et al, 2009). (Moench) is among the most familiar and widely known species of the family Malvaceae (Naveed et al, 2009). It is annual vegetable reaped in summer, and thought to be native to Africa, South East Asia and North Australia in the Pacific (Pandita et al, 2010). There are many ways to insect infestation, but normally such pests are controlled by hazardous chemicals, which, when released into the environment, can have a negative global impact. Such concerns have created a need for analogous controls designed with safety in mind
