Injury by herbivores is a major biotic stress that limits soybean [Glycine max (L.) Merrill] crop production. Among the main insect pests, Anticarsia gemmatalis Hübner responsible for causing significant economic damage in soybean. The primary management strategy this chemical control and use of Bt transgenic Alternative strategies, such as host plant resistance, are considered an efficient less-aggressive method, especially association with other strategies part integrated pest (IPM)...
Abstract BACKGROUND Crop pest management requires an understanding of the complex interactions among species that potentially impact crop yield. In soybean, velvetbean caterpillar, Anticarsia gemmatalis (Hübner), and soybean looper, Chrysodeixis includens (Walker), are described as key pests, sharing same feeding guild. We assessed intraguild these under laboratory conditions. Fitness cost study was conducted to examine influence competition on insect development. A video tracking system...
Fruit flies (Diptera: Tephritidae) are considered to be one of the principal groups pests in fruit culture worldwide. The objective this study was investigate oviposition by Anastrepha fraterculus (Wiedemann) and Ceratitis capitata citrus fruits assess development these species relation maturity orange fruits. experiments were carried out under controlled temperature conditions (25 ± 2 °C), RH (70 10%), photoperiod (12:12 h L:D). Oviposition evaluated exposure (with without choice)...
Abstract Fitness in parasitoids is generally influenced by host quality. We evaluated the development parameters of Doryctobracon areolatus (Hymenoptera: Braconidae) parasitoid on Anastrepha fraterculus (Diptera: Tephritidae) larvae, reared artificial diets with different protein sources. Larvae A. were based 1) raw wheat germ (control); 2) whole rice flour; 3) corn and, 4) flour + soybean meal. The larvae used for D. areolatus, to evaluate number offspring/female, emergence rate, sex ratio,...
Abstract Anastrepha fraterculus (Diptera: Tephritidae) is considered an important pest in Neotropical countries. The laboratory rearing of this species should reproduce conditions nature; thus, special attention required to the nutritional quality diets for larval development. Protein components (wheat germ) are costly and account most production costs lab insect rearing. In sense, work aimed identify ingredients replace wheat germ, without compromising diet A. . We tested composed whole...
Abstract. Plant resistance is considered as an important pillar of Integrated Pest Management (IPM), being a highly targeted method since less harmful to the environment, if compared other tactics such chemical control. Abiotic factors are those related environment and have direct influence on dynamics interaction between insects plants. The abiotic altitude, temperature, humidity, luminosity, wind soil fertility, among others, do not act alone, but in complex net that leads insect...
Abstract Integrated pest management (IPM) and insect resistance (IRM) in a cropping system demands comprehensive understanding of behavior, including larval movement. We evaluated the movement velvetbean caterpillar, Anticarsia gemmatalis (Hübner), non- Bt soybean cultivar. Third to fifth instars were infested different combinations vegetative reproductive stages, on-plant was characterized across select time points. The dispersion among plants positions orientations assessed by releasing...
