In the 1996 Winter issue of Fruit Notes, we reported results of our 1995 research on plum curculio responses to unbaited “Tedders” traps. These traps are pyramidal in shape, dark in color, and are placed on the ground. They capture curculios that arrive on the trap surface and subsequently crawl upward to the tip, where they enter an inverted screen funnel (a cotton boll weevil trap top) placed...

Effects of soil condition and burial on boll weevil, Anthonomus grandis grandis Boheman, mortality in fallen cotton, Gossypium hirsutum L., fruit were assessed in this study. During hot weather immediately after summer harvest operations in the Lower Rio Grande Valley of Texas, burial of infested fruit in conventionally tilled field plots permitted significantly greater survival of weevils than...

Gossypium barbadense, famous for the superior quality of its fibers, is the second most cultivated cotton in the world. In order to determine the genetic basis of its agronomic traits, a linkage map was constructed and QTLs were analyzed. A total of 15,971 markers, including gSSRs, EST-SSRs, SRAPs, and SSCP-SNPs, were used to construct an intraspecific linkage map of G. barbadense with 124 F2 i...

The Southeastern Boll Weevil Eradication Program has proposed reducing maintenance program costs in eradicated zones by using an extended-life "superlure" in traps to detect populations of the boll weevil, Anthonomus grandis grandis Boheman. However, superlure effectiveness has not been extensively evaluated. We compared the superlure (30 mg of eugenol plus 25 mg of grandlure) to a standard lur...

A field study examined the temporal patterns of boll weevil mortality provided by two commercially available kill strips, Hercon VaporTape II and Plato Insecticide Strip, and to evaluate the impacts of these devices on weevil escape from traps. Both types of kill strips produced similar levels of weevil mortality with the exception of the last two inspection intervals (30 and 46 h after continu...

We hybridized 10 chromosome segment substitution lines (CSSLs) each from two CSSL populations and produced 50 F1 hybrids according to North Carolina Design II. We analyzed the genetic effects and heterosis of yield and yield components in the F1 hybrids and parents in four environments via the additive-dominance genetic model. Yield and yield components of the CSSLs were controlled by combined ...

Salicylic acid (2-hydroxybenzoic acid) may help regulate several plant functions, including systemic acquired resistance to pathogens and the formation of flowers. The objective of this study was to characterize the effects of foliar-applied salicylic acid on cotton (Gossypium hirsutum L.) flowering, boll retention, and yield. Field experiments were conducted at two Mississippi locations in 199...

This study was carried out during 2002-2005 in the east Mediterranean region of Turkey (in Kahramanmaras province), at the experimental field of Agricultural Faculty of Kahramanmaras Sutcu Imam University. Four naturally coloured cotton lines (light brown, dark brown, cream and green) (G. hirsutum L.) brought from Azerbaijan National Academy, Genetic Resources Institute and white linted cotton ...

Reproductive boll weevil populations are typically identified by the presence of a frass seal and protuberance at the oviposition site in cotton squares. However, despite the occurrence of other oviposition puncture seal types and their use in previous fecundity studies, the relationship of these respective puncture seal types and oviposition has not been clearly examined. In this study, newly ...
