Control of silverleaf whitefly, cotton aphid and kanzawa spider mite with oil and extracts from seeds of sugar apple.
Development of alternative methods for pest management is needed with the increased concern for adverse effects of pesticides for human health and the environment. The main goal of our study was to test the oil from seeds of sugar apple (Annona squamosa), an edible tropical fruit for pest control. The oil pressed out of seeds was as effective in controlling the silverleaf whitefly, Bemisia arge...
متن کاملEffects of temperature and dietary sucrose concentration on respiration in the silverleaf whitefly, Bemisia argentifolii.
A system consisting of a flow-through chamber connected to a commercial infrared gas analysis system was developed to measure homopteran respiration during feeding. Using this system, respiration rates of 202 and 206 µmol CO(2) h(-1) g(-1) (4.96 and 5.04 ml CO(2) h(-1) g(-1)) were determined for whiteflies and cotton aphids, respectively, at 25 degrees C on diets containing 15% sucrose. These r...
متن کاملEvaluation of the Entomopathogenic Fungi Beauveria bassiana and Paecilomyces fumosoroseus for Microbial Control of the Silverleaf Whitefly, Bemisia argentifolii
c s t u a 1 b d f a a i 1 b Collaborative research was conducted at the USDARS Subtropical Agricultural Research Center in southrn Texas to assess the microbial control potential of eauveria bassiana and Paecilomyces fumosoroseus gainst Bemisia whiteflies. Laboratory assays demontrated the capacity of both pathogens to infect Bemisia rgentifolii nymphs on excised hibiscus leaves incubated t rel...
متن کاملLocal and systemic changes in squash gene expression in response to silverleaf whitefly feeding.
Squash genes (SLW1 and SLW3) induced systemically after silverleaf whitefly feeding were identified. Differences in the local and systemic expression of SLW1 and SLW3 after feeding by the closely related silverleaf and sweetpotato whiteflies were observed. Temporal and spatial studies showed that SLW1 and SLW3 were induced when second, third, and fourth nymphal instars were feeding. Although on...
متن کاملMultitrophic interactions of the silverleaf whitefly, host plants, competing herbivores, and phytopathogens.
Our laboratory found that silverleaf whitefly (SLW; Bemisia argentifolii Bellows & Perring) feeding alters host plant physiology and chemistry. The SLW induces a number of host plant defenses, including pathogenesis-related (PR) protein accumulation (e.g., chitinases, beta-1,3-glucanases, peroxidases, chitosanases, etc.). Induction of the PR proteins by SLW feeding occurs in various plant speci...
