Longevity of Overwintered Boll Weevils (Coleoptera: Curculionidae) On Pre-fruiting Cotton
Field-cage studies have indicated that prefruiting cotton (Gossypium hirsutum L.) is not nutritionally adequate to support extended longevity of overwintered boll weevils (Anthonomus grandis Boheman), but these studies did not separate the respective effects of environment and nutrition on survival. The longevity of trapcaptured overwintered weevils fed pre-fruiting cotton under controlled cond...
متن کاملPotential for transport of boll weevils (Coleoptera: Curculionidae) to the cotton gin within cotton modules.
There is concern that cotton gins located in boll weevil, Anthonomus grandis grandis Boheman, eradication zones serving customers in adjacent infested zones may serve as a site for boll weevil reintroductions if weevils are transported alive inside cotton modules. We surveyed fields in three distinct areas of Texas and found that weevils can be present in large numbers in cotton fields that hav...
متن کاملPotential for escape of live boll weevils (Coleoptera: Curculionidae) into cottonseed, motes, and cleaned lint at the cotton gin.
Reintroductions of the boll weevil, Anthonomus grandis grandis Boheman, into areas of the United States where it has been eradicated or suppressed are very expensive to mitigate. There is concern that a cotton gin in an eradication zone may serve as a site of boll weevil reintroductions when processing cotton harvested in a neighboring infested zone. Similarly, there is a question whether weevi...
متن کاملDispersal of boll weevils (Coleoptera: Curculionidae) from cotton modules before ginning.
We characterized the level of risk of boll weevil, Anthonomus grandis grandis Boheman, reintroduction to an eradication zone posed by dispersal from cotton modules during and after transport to the gin. Mark-release-recapture experiments in August and September in Texas indicated that most weevils disperse rapidly from the module surface, temperature permitting, unless confined under a module t...
متن کاملEarly-season colonization patterns of the boll weevil (Coleoptera: Curculionidae) in Central Texas cotton.
It is commonly believed that colonization of early-season cotton, Gossypium hirsutum L., by overwintered boll weevils, Anthonomus grandis grandis Boheman, is concentrated on field margins. However, supporting experimental evidence is not available. In 1999 and 2000, we examined colonization patterns of overwintered boll weevils in Central Texas cotton on the bases of adult collections by a pneu...
