Abstract:
... The boll weevil, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), is one of the most important pests of cotton production worldwide. The objective of this work was to develop a sequential sampling plan for the boll weevil. The studies were conducted in Maracaju, MS, Brazil, in two seasons with cotton cultivar FM 993. A 10,000-m² area of cotton was subdivided into 100 of 10- by 10-m ...

Abstract:
... The soybean looper, Chrysodeixis includens (Walker) (Lepidoptera: Noctuidae), is a major defoliating pest of soybeans, Glycine max (L.) Merrill, in Louisiana. However, other alternate host crops in the agroecosystem have the potential to impact C. includens populations. Life table statistics of C. includens on four host plants were evaluated. C. includens larvae were fed leaves of three cotton Gos ...

Abstract:
... Use of plant secondary metabolic compounds is an important method for insect pest control. In this study, the survival, development, and reproduction of Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) MEAM1 cryptic species were compared over two consecutive generations on three cotton cultivars of different gossypol levels. Both cotton cultivar and generation significantly affected the fitness ...

Abstract:
... The ability to monitor verde plant bug, Creontiades signatus Distant (Hemiptera: Miridae), and the progression of cotton, Gossypium hirsutum L., boll responses to feeding and associated cotton boll rot provided opportunity to assess if single in-season measurements had value in evaluating at-harvest damage to bolls and if multiple in-season measurements enhanced their combined use. One in-season v ...

Abstract:
... Lesquerella, Physaria fendleri (A. Gray) S. Watson, is a mustard native to the western United States and is currently being developed as a commercial source of valuable hydroxy fatty acids that can be used in a number of industrial applications, including biolubricants, biofuel additives, motor oils, resins, waxes, nylons, plastics, corrosion inhibitors, cosmetics, and coatings. The plant is culti ...

Abstract:
... Cotton aphids, Aphis gossypii Glover (Homoptera: Aphididae), obtained from cotton, Gossypium hirsutum L., fields in the Gorgan region of northern Iran, were colonized on 'Varamin' cotton plants in a growth chamber. The development, survivorship, and life table parameters of the cotton aphid were evaluated at 27.5 +/- 1 degrees C, 65 +/- 10% RH, and aphotoperiod of 14:10 (L:D) h of artificial light ...

Abstract:
... The effect of twospotted spider mites, Tetranychus urticae Koch, on the yield and fiber quality of cotton was studied at high-yield levels in Australia over four field seasons. Significant reductions in yield, fiber quality, and seed viability were observed and were found to be related to the time of infestation and rate of development of twospotted spider mite populations. Early infestations (at ...

Abstract:
... The effect of early-season cotton, Gossypium hirsutum L., square loss and insect control (primarily thrips, Frankliniella occidentalis (Pergande)), on the ability of cotton plants to replace lost fruit as well as maintain lint quality was examined in several field trials of differing experimental design in Arizona during 1986-1987. All trials indicated some degree of compensation for damage to fru ...

Abstract:
... Oviposition and larval development of pink boll worm (PBW), Pectinophora Gossypiella (Saunders), on a breeding stock of upland cotton, Gossypium hirsutum L., designated AET-5, was compared to that on a commercial cultivar, 'Deltapine 61' (DPL-61), in greenhouse no-choice and free-choice tests, and in field free-choice tests. The field resistance of AET-5 was caused mainly by lower PBW oviposition. ...
