The seasonal occurrence of the beet armyworm, Spodoptera exigua (Hübner), and the southern armyworm, Spodoptera eridania (Cramer), was monitored over a 2year period using International Pheromones, Ltd. Moth Traps baited with rubber septa impregnated with pheromone blends identified from conspecific females and also with pheromone emitted by live female beet armyworm moths. The pheromone blend...
متن کاملToxicity of Some Commonly Used Synthetic Insecticides Against Spodoptera exigua (Fab) (Lepidoptera: Noctuidae)
Spodoptera exigua (Lepidoptera: Noctuidae) is one of the major pests of many crops in Pakistan. Effectiveness of different insecticides was evaluated against field populations of 2 instar larvae of S. exigua under laboratory conditions because in lepidopterous pests resistance is developed in 3 instars. Bioassays were performed through leaf dip method to evaluate the doseand time-mortality resp...
متن کاملSwitching among natal and auxiliary hosts increases vulnerability of Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae) to insecticides
The role of insecticidal application and host plant resistance in managing Spodoptera exigua has been well documented, but the effect of different host plants, on which the pest cycles its population in the field, has seldom been investigated. Therefore, we have studied the vulnerability of S. exigua against commonly used insecticides (cypermethrin, chlorpyrifos, lufenuron, and emamectin benzoa...
متن کاملGeographic Origin and Host Cultivar Influence on Digestive Physiology of Spodoptera exigua (Lepidoptera: Noctuidae) Larvae
Digestive enzymatic activity in three geographic strains (Miandiab, Kalposh and Moghan regions) of Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae) reared on different sugar beet cultivars (Dorothea, Rozier, Persia and Perimer) was studied under laboratory conditions (25 ± 1 °C, 65 ± 5% RH, and a photo period of 16:8 (L:D) h photoperiod). The results of this study demonstrated that digestive...
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) ...
