Feeding and Dispersal Behavior of the Cotton Leafworm, Alabama argillacea (Hübner) (Lepidoptera: Noctuidae), on Bt and Non-Bt Cotton: Implications for Evolution and Resistance Management
The host acceptance of neonate Alabama argillacea (Hübner) (Lepidoptera: Noctuidae) larvae to Bt cotton plants exerts a strong influence on the potential risk that this pest will develop resistance to Bt cotton. This will also determine the efficiency of management strategies to prevent its resistance such as the "refuge-in-the-bag" strategy. In this study, we assessed the acceptance of neonate...
متن کاملEstimate of Alabama argillacea (Hübner) (Lepidoptera: Noctuidae) development with nonlinear models.
The objective of this work was to evaluate which nonlinear model [Davidson (1942, 1944), Stinner et al. (1974), Sharpe & DeMichele (1977), and Lactin et al. (1995)] best describes the relationship between developmental rates of the different instars and stages of Alabama argillacea (Hübner) (Lepidoptera: Noctuidae), and temperature. A. argillacea larvae were fed with cotton leaves (Gossypium hi...
متن کاملARTHROPOD BIOLOGY Feeding and Life History of Spodoptera exigua (Lepidoptera: Noctuidae) on Different Host Plants
Consumption rates, development times, and life table parameters of the beet armyworm, Spodoptera exigua (Hübner), were determined on Þve host plants: cabbage, Brassica oleracea capitata L; cotton, Gossypium hirsutum L.; bell pepper, Capsicum annuum L.; pigweed, Amaranthus retroflexus L.; and sunßower, Helianthus annuus L. Mean total leaf weight consumed by larvae was highest in cabbage (2.7 g) ...
متن کاملWithin-plant distribution of cotton aphid (Hemiptera: Aphididae) in cotton cultivars with colored fibers.
We describe the vertical and horizontal distribution of the cotton aphid Aphis gossypii Glover within a cotton plant in two cotton (Gossypium hirsutum Linnaeus) cultivars (BRS Safira and BRS Rubí) with colored fiber over the time. Measurements of aphid population dynamics and distribution in the cotton plants were recorded in intervals of seven days. The number of apterous or alate aphids and t...
