Abstract

The cotton plant has a profound affect on the behavior and ability of parasites to successfully attack the boll weevil,Anthonomus grandis Boheman. The most important native parasite of the boll weevil,Bracon mellitor Say, prefers to oviposit on Frego bract cotton rather than normal bract cotton. An imported parasite,Heterolaccus grandis Burks prefers ovipositions on normal bract cotton rather than Frego.

Résumé

Le coton a un effet important sur le comportement et les capacités des parasites du charançon,Anthonomus grandis Boheman. Le principal parasite indigène,Bracon mellitor Say préfère pondre sur les bractées Frego plutôt que sur les bractées normales.

Un parasite importé,Heterolaccus grandis Burks dépose ses œufs de préférence sur les bractées normales plutôt que sur les bractées Frego.
