Divergent life histories between wild and commercially-sourced Cotesia flavipes (Hymenoptera: Braconidae) parasitizing four species of Diatraea (Lepidoptera: Crambidae)

Leidy Salamanca et al.

Summary: Moths of the genus Diatraea Guilding are important pests of sugarcane in Colombia, including species such as D. busckella, D. indigenella, D. saccharalis, and D. tabernella. This study compares the performance of two populations of the parasitoid Cotesia flavipes on these host species, showing differences in parasitism success and development speed. Commercially-sourced parasitoids performed worse on host species other than D. saccharalis, suggesting potential impacts of continuous rearing on a single host species.

Genetic analyses and detection of point mutations in the acetylcholinesterase-1 gene associated with organophosphate insecticide resistance in fall armyworm (Spodoptera frugiperda) populations from Uganda

Geresemu Omuut et al.

Summary: The genetic identity and diversity of fall armyworm populations in Uganda were revealed by sequencing samples. The results showed low genetic diversity but rapid development of resistance to organophosphates and carbamates. This research is important for pest surveillance and resistance detection.

Sustainable management of fall armyworm, Spodoptera frugiperda (JE Smith): challenges and proposed solutions from an African perspective

Shingirayi Nyamutukwa et al.

Summary: The fall armyworm is a threat to food security in Africa, with the potential to cause significant losses in maize production. There is a lack of clear national policies and regulations, as well as sustainable management options, to effectively combat this pest. Conservation of natural enemies and the use of sustainable control strategies show promise in managing the fall armyworm.

Insecticide resistance in Australian Spodoptera frugiperda (JE Smith) and development of testing procedures for resistance surveillance

Lisa Bird et al.

Summary: Spodoptera frugiperda populations in Australia show decreased sensitivity to insecticides, especially in Group 1 and synthetic pyrethroids. Emamectin benzoate, chlorantraniliprole, and spinetoram are the most effective insecticides against the pest.

Summary: This study assessed the toxicity of seven synthetic insecticides on the fall armyworm larvae and found that broflanilide and abamectin were the most toxic. The results provide a basis for the development of novel insecticides for controlling fall armyworm populations.

Agronomic Factors Influencing Fall Armyworm (Spodoptera frugiperda) Infestation and Damage and Its Co-Occurrence with Stemborers in Maize Cropping Systems in Kenya

Daniel Munyao Mutyambai et al.

Summary: This study assessed the co-occurrence, infestation, and damage of Fall armyworm (FAW) with resident stemborers in maize cropping systems across different agro-ecological zones in Kenya. The results demonstrated that FAW dominates resident stemborers in maize fields and its infestation and damage are highest in coastal lowlands compared to other areas. Agronomic practices, such as mixed cropping systems with rainfed production and frequent weeding, can reduce FAW infestation and damage. Young vegetative maize plants are more susceptible to infestation and damage. Different maize varieties also show varying levels of infestation and damage, with Pioneer having the least damage.

Chemical Control and Insecticide Resistance in Spodoptera frugiperda (Lepidoptera: Noctuidae)

Johnnie Van den Berg et al.

Summary: This paper reviews the history of insecticide resistance in the fall armyworm and discusses the factors that influence control efficacy and resistance evolution, such as life history traits, migration ecology, and chemical control practices. The indirect impact of national policies on pesticide use and control efficacy is also examined, highlighting the importance of integrated pest management.

Integrated management of Spodoptera frugiperda 6 d years post detection in Africa: a review

Ghislain Tepa-Yotto et al.

Summary: The introduction of fall armyworm to Africa has changed pest control strategies, with the discovery of resident parasitoid species reducing the use of synthetic insecticides. Some biopesticides have shown promise, but there are still knowledge gaps, particularly in host-resistance potential.

Impact of the exotic fall armyworm on larval parasitoids associated with the lepidopteran maize stemborers in Kenya

Bonoukpoe Mawuko Sokame et al.

Summary: The study shows that the exotic pest FAW can impact existing stemborer-parasitoid interactions associated with maize, even though the existing parasitoids cannot use FAW as hosts. The parasitoids attack FAW larvae but cannot reproduce, and in olfactometer bioassays, they are more attracted to plants infested by FAW.

Spatio-temporal partitioning and sharing of parasitoids by fall armyworm and maize stemborers in Cameroon

Albert F. Abang et al.

Summary: Research on the interaction between fall armyworm (FAW) and stemborers in maize trials in Cameroon revealed that there are temporal and spatial differences between the two pests, and the sharing of parasitoids by both species provides a unique opportunity for augmentative biocontrol.

A deadly encounter: Alien invasive Spodoptera frugiperda in Africa and indigenous natural enemy, Cotesia icipe (Hymenoptera, Braconidae)

Samira Abuelgasim Mohamed et al.

Summary: The invasion and spread of Spodoptera frugiperda pose a significant threat to maize and sorghum farming communities in sub-Saharan Africa. Current efforts focused on synthetic pesticides are economically unviable and environmentally hazardous, making biological control using parasitoids like Cotesia icipe a more sustainable alternative. This study found that C. icipe preferentially targets younger larval stages of the pest and identified suitable habitats for its establishment in current and future climates.

Baseline Susceptibility of Spodoptera frugiperda Populations Collected in India towards Different Chemical Classes of Insecticides

Mahesh Kulye et al.

Summary: Fall armyworm (FAW) is a highly destructive moth pest that poses a major threat to maize production in India. Control measures rely on chemical insecticides and transgenic crop plants, but FAW has developed resistance to insecticides. Evaluating its susceptibility to different chemical classes of insecticides is crucial for effective management strategies.

Could fall armyworm, Spodoptera frugiperda (J. E. Smith) invasion in Africa contribute to the displacement of cereal stemborers in maize and sorghum cropping systems

Girma Hailu et al.

Summary: This study in Uganda assessed the infestation of fall armyworm (FAW) and cereal stemborers on maize and sorghum, revealing that FAW infestation was higher on maize while stemborer infestation was higher on sorghum. Historical records indicated a significant decline in stemborer infestation in maize starting in 2016, suggesting an early arrival of FAW in Uganda. Integrated Pest Management (IPM) strategies should consider managing FAW and stemborers together in maize and other cereal hosts.
