Three Boll Weevil Diapause Myths in Perspective

Diapause in the Boll Weevil (Coleoptera: Curculionidae) : Seasonal Occurrence in Mississippi Populations

Ann. Entomol. Sm. Am. 92(3): 362-395 (1999) ABSTRACT This study examines the diapause response among boll weevils collected as immatures in squares at different times of the summer and held under simulated field photoperiods and temperatures of northern Mississippi. The percentage of adults exhibiting prediapause increased seasonally, starting with the 1st generation in July and achieving a max...

Temperature Influences on Diapause Induction and Survival in the Boll Weevil (Coleoptera: Curculionidae)

The boll weevil, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), has been the most important pest of cotton (Gossypium spp.) wherever it occurs. Although eradication programs in the United States have reduced the range of this pest, the weevil remains an intractable problem in subtropical Texas, Mexico, and much of South America. A key to managing the weevil in the subtropics an...

A hexamerin protein, AgSP-1, is associated with diapause in the boll weevil(1).

The objective of this research was to identify a reliable biochemical indicator for diapause (dormancy) in the boll weevil, Anthonomus grandis. Hemolymph polypeptides from reproductive and diapausing weevils were compared using denaturing sodium dodecyl sulpfate (SDS)-polyacrylamide gel electrophoresis (PAGE). A 77-kDa protein, which proved to be a hexamerin (AgSP-1), strongly correlated with m...
