The preponderance of pod sucking bugs of cowpea and their control using botanical and synthetic insecticides in Samaru, Nigeria

The preponderance and effect of extra application of synthetic insecticide, lamda-cyhalothrin and

botanical, neem seed extracts to control pod sucking bugs of cowpea were investigated in 2007 and

2008, respectively at Samaru, Zaria, Nigeria. The design used was Randomized Complete Block

Design. The cowpea variety used was SAMPEA-7, which was sown on 4th and 6th August in 2007 and

2008, respectively. Six treatments were used which were designated as T1, for two sprays of Landa-

cyhalothrin; T2 for three sprays of Lamda-cyhalothrim, T3 for four sprays of Lamda-cyhalothrin; T4

for five sprays of neem seed extract; T5 for six sprays of neem seed extract and T6 as a control where

there was no spray of either of the insecticides. The treatments were replicated four times. The

parameters assessed were number of sucking bugs per square metre, percentage of different species

of sucking bugs, percentage of damaged pods per plant and yield per hectare. Five pod sucking bugs

were found infesting cowpea pods  in                             the following order ofpreponderance;Clavigralla

tomentosicollis Stal. (66.3%), Halydocoris ventralis Dall. (15.7%), Mirperus jaculus Wstw. (9.0%),

Riptotus dentipes Fab. (7.8%), and Anoplocnemis curvipes Fab. (1.2%). There was significant (P
