The beet armyworm, Spodoptera exigua (Hübner) (Lepidoptera: Noctuidae), is a serious polyphagous insect pest worldwide. This species is known as a long-distance migrant, and previous studies on its migration have been mostly carried out in regions where it can overwinter. However, what pattern of seasonal migration this species exhibits in regions where it cannot overwinter (i.e., the 'summer b...

Abstract Anti-oviposition induced by Cordyceps fumosorosea FG340 to Spodoptera exigua and its persistence had been assessed on the Chinese cabbage seedlings sprayed with 0, 10 6 , 7 8 conidia per mL in greenhouse laboratory. In a randomized complete block, four couples (males females) of moths were released each cage. laboratory, percentage egg laid varied significantly between treatments 59.8,...

One of the agricultural commodities that has a high selling value and consumption level is shallot (Alium ascalonicum). However, productivity shallots known to be susceptible plant-destroying organisms, such as caterpillar (Spodoptera exigua). Currently, most farmers control S. exigua using synthetic insecticides. Synthetic insecticides are poisonous use for long time period will cause resistan...

In general, caterpillar herbivores with a narrow host preference (specialists) have evolved mechanisms to circumvent specific plant defenses. contrast, caterpillars broader range (generalists) may manipulate phytohormone pathways common many species attenuate induced Many studies compared responses specialist versus generalist caterpillars. this study evaluates the response of Arabidopsis thali...
