ABSTRACT
Biology of cowpea flower thrips Megalurothrips sjostedti, was
studied under field conditions.
Population studies showed that the trend of thrips populations
was closely tied with the flowering cycle of the cowpea crop.
Peak thrips populations coincided with peak flowering of the crop.
The seasonal abundance of thrips was mainly governed by weather
factors. Thrips were found to oviposit mainly in the calyx of
the cowpea flower.
Evaluation of different sampling methods for thrips on
cowpea indicated that water traps were most consistent. An
artificial infestation method was developed for evaluating
resistance of cowpeas to flower thrips in the screenhouse.
Comparative yield studies without protection against flower
thrips revealed a superior performance of cowpea cultivar TVx 3236
over other cultivars.
The first phase of a negative field screening of cowpea germplasm
showed that further sources of resistance to flower thrips were
apparent in some accessions.
