Research Notes
Spodoptera frugiperda, Fall Armyworm (FAW), poses an existential threat to farmers in Africa given their destructive effect on crops. This is essentially the case in south-eastern Nigeria where major crops such as cassava and maize are highly vulnerable to the adverse effects of the pest. This paper reviewed published work on the availability of biopesticides …

Research Notes
The invasive polyphagous pest fall armyworm Spodoptera frugiperda, (Lepidoptera: Noctuidae) is a migratory pest of maize in Asia and other countries including Pakistan. It mostly feed on leaves at larval stage and this pest can be controlled by various management strategies including chemical control but the pest has now developed resistance against major insecticides. However, …

Research Notes
Second generation Bt crops (insect resistant crops carrying Bacillus thuringiensis genes) combine more than one gene coding for insecticidal proteins in the same plant to provide a better control of agricultural pests. Some of the new combinations involve co-expression of cry and vip genes. Since Cry and Vip proteins have different midgut targets and possibly …

Research Notes
Bacillus thuringiensis vegetative insecticidal proteins (Vip3A) have been recently introduced in important crops as a strategy to delay the emerging resistance to the existing Cry toxins. The mode of action of Vip3A proteins has been studied in Spodoptera frugiperda with the aim to characterize their binding to the insect midgut. Immunofluorescence histological localization of Vip3Aa …

Research Notes
  Bioinsecticides based on Bacillus thuringiensis have long been used as an alternative to synthetic insecticides to control insect pests. In this review, we focus on insects of the genus Spodoptera, including relevant polyphagous species that are primary and secondary pests of many crops, and how B. thuringiensis toxins can be used for Spodoptera spp. …

Research Notes
The bacterium Bacillus thuringiensis produces insecticidal Vip3 proteins during the vegetative growth phase with activity against several lepidopteran pests. To date, three different Vip3 protein families have been identified based on sequence identity: Vip3A, Vip3B, and Vip3C. In this study, we report the construction of chimeras by exchanging domains between Vip3Aa and Vip3Ca, two proteins …
