Durocher-Granger, L. Published a research work on the factors influencing the occurrence of fall armyworm parasitoids in Zambia. Their findings indicate that there is potential for increasing local populations of natural enemies of FAW through conservation biological control programmes and develop safe and practical control methods for smallholder farmers.

Recent FAW natural enemies scouting have reveled very interesting observation. FAW sampling done in 3 regions of Ghana West Africa showed beneficial nematodes emerging from the FAW larvae. In some instances there’s been more than one nematode emerging from the FAW larvae. Under which category of natural enemies do we place them(eg. Pathogens, Predators etc. …

Exotic invasive insect herbivores have the potential to interfere with existing herbivores-natural enemies’ interactions in new environments. Understanding the acceptability and suitability of a new invasive pest such as Fall Armyworm (FAW), Spodoptera frugiperda J.E. Smith (Lepidoptera: Noctuidae) to the existing parasitoids-maize stemborers interactions is the first step in elucidating the impact that this exotic …

Research Notes
In July 2019, we found a species of egg parasitoid wasp emerged from Spodoptera frugiperda eggs collected in southeast of Guizhou province. This parasitoid species was identified by molecular method as Telenomus remus. To test the parasitic efficacy of T. remus against S. frugiperda and S. litura eggs, we investigated the parasitic rates, offspring number per host eggs, body size, …

Research Notes
Telenomus remus has been viewed as an effective biological control agent against Spodoptera frugiperda eggs. The investigation of basic biological characteristics of T. remus will supply the reference for the mass rearing and application of T. remus. In this study, we described the characteristics of parasitic behavior of T. remus females and the morphological characteristics of T. remus females and …

Fall armyworm Spodoptera frugiperda ( Smith) is a new invasive pest causing serious damages in China. Among egg parasitoids,Trichogramma are the dominant biological control agents that has been applied to control lepidopteran pests of crops,vegetables and forests worldwide. To evaluate the possibility and efficiency of local Trichogramma species of northeastern China on S. frugiperda eggs,we …

Research Notes
Trichogramma species make up one of the most commonly used groups of natural enemies for biological control programs worldwide, and have been the best natural enemies suitable for mass production with low cost. Since the 1960s, improved mass production of Trichogramma and better augmentative release methods to suppress agricultural pests have been achieved. We review …

Research Notes
The research focuses on studying the interaction (Synergy/competition) and reproductive capacities of two Spodoptera frugiperda larval parasitoids (Coccygidium luteum and Cotesia icipe) in Ghana. The research also studies the life span and larval instar preference of the parasitoids. Findings from the study will enhance knowledge on the tri-trophic interactions in the ecosystems of parasitoids and …
