“…Combining the clean feeding system with the use of antiviral drugs could eliminate SGH symptoms from a colony with a SGH prevalence of 24% within six months [ 170 ]. This approach was implemented for the G. pallidipes colony in NICETT and resulted in a stable colony with a sustainable output in sterile males for the implementation of the SIT program [ 171 , 172 ].…”

The Joint FAO/IAEA Centre (formerly called Division) of Nuclear Techniques in Food and Agriculture was established in 1964 and its accompanying laboratories in 1961. One of its subprograms deals with insect pest control, and has the mandate to develop and implement the sterile insect technique (SIT) for selected key insect pests, with the goal of reducing the use of insecticides, reducing animal and crop losses, protecting the environment, facilitating international trade in agricultural commodities and improving human health. Since its inception, the Insect Pest Control Laboratory (IPCL) (formerly named Entomology Unit) has been implementing research in relation to the development of the SIT package for insect pests of crops, livestock and human health. This paper provides a review of research carried out between 2010 and 2020 at the IPCL. Research on plant pests has focused on the development of genetic sexing strains, characterizing and assessing the performance of these strains (e.g., Ceratitis capitata), elucidation of the taxonomic status of several members of the Bactrocera dorsalis and Anastrepha fraterculus complexes, the use of microbiota as probiotics, genomics, supplements to improve the performance of the reared insects, and the development of the SIT package for fruit fly species such as Bactrocera oleae and Drosophila suzukii. Research on livestock pests has focused on colony maintenance and establishment, tsetse symbionts and pathogens, sex separation, morphology, sterile male quality, radiation biology, mating behavior and transportation and release systems. Research with human disease vectors has focused on the development of genetic sexing strains (Anopheles arabiensis, Aedes aegypti and Aedes albopictus), the development of a more cost-effective larvae and adult rearing system, assessing various aspects of radiation biology, characterizing symbionts and pathogens, studying mating behavior and the development of quality control procedures, and handling and release methods. During the review period, 13 coordinated research projects (CRPs) were completed and six are still being implemented. At the end of each CRP, the results were published in a special issue of a peer-reviewed journal. The review concludes with an overview of future challenges, such as the need to adhere to a phased conditional approach for the implementation of operational SIT programs, the need to make the SIT more cost effective, to respond with demand driven research to solve the problems faced by the operational SIT programs and the use of the SIT to address a multitude of exotic species that are being introduced, due to globalization, and established in areas where they could not survive before, due to climate change.

“…These viruses predominantly affect lepidopteran species and are characterized by their crystalline polyhedral protein capsid, which dissolves in insect larval midguts to release the viral particles and allow infestation to occur (Harrison et al., 2008). As the mortality rate from such viruses is typically close to 100%, these can be highly effective biocontrol agents (Abd‐Alla et al., 2020). Different NPV strains show varying insecticidal activity against a given target species (Ogembo et al., 2009; Rowley et al., 2011); hence, there has been considerable research activity in isolating and characterizing the activity of different H. armigera NPV strains from around the world (Baillie & Bouwer, 2012; Ogembo et al., 2009) and in creating recombinant NPVs with increased toxicity (Sun et al., 2004).…”

Helicoverpa armigera Hübner (Lepidoptera: Noctuidae) is one of the most damaging insect pests globally, causing estimated global economic losses of over 3 billion US dollars annually. Crops most affected include cotton, tomato, soybean, grain crops such as corn and sorghum, chickpea and other pulses. Adults of this species possess strong migratory abilities (>2000 km), high fecundity and rapid reproductive rates; completing 4–6 generations per year in most cropping regions. Furthermore, the larvae are polyphagous, with a wide and diverse host range and possess the ability to enter diapause in order to survive adverse climatic conditions. At present, it is distributed across most of Oceania, Asia, Africa and southern Europe and has recently spread to South America. Various control measures have been trialled or proposed for the treatment of this pest, including synthetic insecticides, phytopesticides, microbial pesticides, macro‐biocontrol agents (both parasitoids and predators) and the development of genetically modified crops (e.g. Bt cotton). Successful control necessitates the use of an integrated pest management (IPM) approach, wherein biological, chemical and physical control measures are combined for the greatest control efficacy.

“…Providing food for the growing human population with safety standards is a great challenge. Consequently, an urgent need has been identified to provide pest control mechanisms acceptable in the large-scale agricultural sector, which is easily reproducible, environmentally sustainable, and without undesired effects on beneficial organisms (Szewczyk et al 2011;Das et al 2019;Abd-Alla et al 2020). Chemical pesticides have demonstrated negative impacts on the environment and public health.…”

“…Viral pesticides emerge as a promising alternative to chemical pesticides to obtain safe products for the environment and to human health, compatible with other sustainable agriculture practices and the growing market demand (Szewczyk et al, 2011;Popham et al, 2016;Grzywacz and Moore, 2017;Abd-Alla et al, 2020). Virus and entomopathogenic fungus are widely used as biocontrol agents in several crops with agricultural and economical importance (Rodriguez- Gómez et al, 2020).…”

“…However, it is necessary to establish standardized and economically appropriate protocols for operational processes and the definition of quality control standards for viral biopesticides to ensure compliance with consumer requirements and facilitate its positioning in the market. Furthermore, these protocols would provide the development of adequate industrial production, in which case production plants or facilities should have a proper design and an acceptable production volume to overcome operation costs (Abd-Alla et al, 2020;Behle and Birthisel, 2013;Grzywacz and Moore, 2017;Jenkins and Grzywacz, 2000;Szewczyk et al, 2011). The production processes for viral bioproducts vary depending on the viral strain, the type of formulation, and the finished product specifications, meaning that a single methodology cannot be used for all preparations (Jenkins and Grzywacz, 2000;Roldão et al, 2011).…”
