Abstract

Six foliar insecticides were evaluated for efficacy in the control of different stages of Clavigralla tomentosicollis, the most important cowpea coreid in Nigeria.

Monocrotophos was highly effective in controlling adults for up to 16 DAT and was statistically better than cypermethrin + dimethoate (Sherpa Plus(R)), deltamethrin, endosulfan and deltamethrin + endosulfan 8 days after treatment. Comparative overall results were obtained between monocrotophos and the mixture of cypermethrin + chlorpyrifos. The best control of nymphs was obtained with monocrotophos, cypermethrin + dimethoate and endosulfan, while the mixtures of cypermethrin + dimethoate and cypermethrin + chlorpyrifos completely inhibited egg hatch. More than 78% egg hatch was obtained from monocrotophos and deltamethrin, while the water-treated control had 96% hatch.

These findings are discussed in the light of product toxicity, residual action and overall reduction of the pod bug populations.


Résumé

Six insecticides furent evalués pour leur efficacité pour le controle des stages de developpement du Clavigralla tomenlosicallis, le plus important des insects nuisibles du petit pois au Nigeria.

Monocrotophos etait plus efficace pour le controle des adults et statisquement mieux 8 jours aprés traitèment que cypermetrin + dimethoate (Sherpa Plus), Deltametrin, endosulfan et deltametrin + endosulfan. Des resultats comparatifs entre monocrotophos et le melange de cypermethrin + chlorpyrifos ont ete enregistrés. Le meilleur controle des nymphes fut obtenu avec monocrotophos, cypermethrin + dimethoate et cypermethrin + chlorpyrifos inhibent completement l'eclosion des oeufs. Plus de 78% des oeufs ont pu éclore lorsqu'ils sont traités au monocrotophos et deltamethrin contre 96% pour traitement à l'eau.

Ces résultats démontrent la toxicité du produit, l'action résidu et une dimunition totale de la population de la punaise de gousse.
