“…Parasitoid wasps have long been used as biocontrol agents of agricultural insect pests [10][11][12] and recently also in livestock hygiene management [13]. Some species of parasitoid wasps can be reared easily on an industrial scale, providing a ready source of pest control on demand [14]. By contrast, the predatory power of hunting wasps (which feed meat protein-often derived from other insects-to their developing brood) in biocontrol is almost entirely overlooked, despite the recognized impact of predatory wasps on wild insect populations [15,16].…”

Social wasps are effective biocontrol agents of key lepidopteran crop pests

Biocontrol agents can help reduce pest populations as part of an integrated pest management scheme, with minimal environmental consequences. However, biocontrol agents are often non-native species and require significant infrastructure; overuse of single agents results in pest resistance. Native biocontrol agents are urgently required for more sustainable multi-faceted approaches to pest management. Social wasps are natural predators of lepidopteran pests, yet their viability as native biocontrol agents is largely unknown. Here, we provide evidence that the social paper wasp Polistes satan is a successful predator on the larvae of two economically important and resilient crop pests, the sugarcane borer Diatraea saccharalis (on sugarcane Saccharum spp.) and the fall armyworm Spodoptera frugiperda (on maize Zea mays ); P. satan wasps significantly reduce crop pest damage. These results provide the much-needed baseline experimental evidence that social wasps have untapped potential as native biocontrol agents for sustainable crop production and food security.

Description du sujet. Dans le cadre d’un projet de biocontrôle de la processionnaire du pin, Thaumetopoea pityocampa Denis & Schiffermüller, l’utilisation de parasitoïdes indigènes pour lutter contre ce ravageur a été étudiée au sein du Laboratoire Biocontrôle à l’UEFM (Unité Expérimentale Entomologie et Forêt Méditerranéenne) à l’INRA PACA. Objectifs. Il est nécessaire de rechercher le meilleur hôte de substitution et de mettre au point son élevage. Plus particulièrement, l'espèce Ooencyrtus pityocampae (Mercet) a été étudiée. Méthode. Thaumetopoea pityocampa étant une espèce allergisante, plusieurs hôtes de substitution ont été comparés pour l’élevage des parasitoïdes : Philosamia ricini (Danovan), Nezara viridula (L.) et Halyomorpha halys (Stål). Les caractéristiques biologiques et la fitness des descendants ont été comparées en conditions de laboratoire (25 ± 1 °C, 75 ± 5 % HR, 16L:8D). Résultats. Philosamia ricini est le meilleur hôte de substitution pour l’élevage d’O. pityocampae pour ce qui est de la quantité et de la qualité des individus produits. Conclusions. Cette étude servira de base à une réflexion sur les possibilités d’utiliser ce parasitoïde dans le cadre de la lutte biologique contre certains ravageurs méditerranéens.

“…Another concern was the benefit: cost of adding quality control units to the facilities. The history of quality control in mass-reared insects and the WGQC through this period was described by Ernst Boller (1986), quality control in insect mass production was reviewed by Leppla and Ashley (1989), and Milton Huettel (1986) produced a relevant book on the genetics of insect behavior.…”

The International Organization for Biological Control Global Working Group on Mass Rearing and Quality Assurance (MRQA) was established in 1980 as the Working Group on Quality Control (WGQC) to assure success of insect mass rearing for pest management that was being developed in the 1950s and 1960s. Due mostly to the efforts of WGQC, quality control became institutionalized in several insect mass rearing facilities during the 1980s. After addressing autocidal control programs, the WGQC concentrated on entomophagous insects, especially testing the quality of commercial biological control products. Universal Implementation of Quality Control for Mass-Reared Arthropods was finally achieved in the 1990s, having encompassed all aspects from insect production to field application and evaluation. This increased scope prompted a name change from WGQC to Arthropod Mass Rearing and Quality Control (AMRQC). Subsequently, the scope of the Working Group was expanded again and it was renamed MRQA to include a range of applications for mass-reared beneficial invertebrates. The geographic range of MRQA recently was extended beyond North and South America and Europe to include India. This expansion continued as insects for food and feed, networking and instruction, and legal and ethical issues were added to the most recent workshop held in Mexico. Thus, the MRQA continues to evolve as additional invertebrate organisms are mass produced for both established and novel applications.
