“…Mass introductions may then be targeted through acclimation, to suit areas of release [26,99,100]. Indeed, previous studies have recommended that thermal acclimation can significantly improve the fitness of laboratory reared insects upon introduction to wild conditions [100][101][102][103], and this approach has even been recommended for field releases using Sterile Insect Technique (SIT) [26]. It has been documented that biological control using predators and parasitoids should aim at developing resilient agro-ecosystems which maintain species' evolutionary potential to improve efficacy.…”

Abstract:The diamondback moth (DBM), Plutella xylostella, is a global economic pest of brassicas whose pest status has been exacerbated by climate change and variability. Southern African small-scale farmers are battling to cope with increasing pressure from the pest due to limited exposure to sustainable control options. The current paper critically analysed literature with a climate change and sustainability lens. The results show that research in Southern Africa (SA) remains largely constrained despite the region's long acquaintance with the insect pest. Dependency on broad-spectrum insecticides, the absence of insecticide resistance management strategies, climate change, little research attention, poor regional research collaboration and coordination, and lack of clear policy support frameworks, are the core limitations to effective DBM management. Advances in Integrated Pest Management (IPM) technologies and climate-smart agriculture (CSA) techniques for sustainable pest management have not benefitted small-scale horticultural farmers despite the farmers' high vulnerability to crop losses due to pest attack. IPM adoption was mainly limited by lack of locally-developed packages, lack of stakeholders' concept appreciation, limited alternatives to chemical control, knowledge paucity on biocontrol, climate mismatch between biocontrol agents' origin and release sites, and poor research expertise and funding. We discuss these challenges in light of climate change and variability impacts on small-scale farmers in SA and recommend climate-smart, holistic, and sustainable homegrown IPM options propelled through IPM-Farmer Field School approaches for widespread and sustainable adoption.

“…Other aspects of mass rearing for edible insects can be imported from the rearing of sterile insects for pest control. Mass rearing can lead to changes in a number of phenotypic traits due to artificial diets, strong laboratory adaptation, and/or inbreeding depression [97].…”

Abstract:The farming of edible insects is an alternative strategy for the production of protein-rich food and feed with a low ecological footprint. The industrial production of insect-derived protein is more cost-effective and energy-efficient than livestock farming or aquaculture. The mealworm Tenebrio molitor is economically among the most important species used for the large-scale conversion of plant biomass into protein. Here, we review the mass rearing of this species and its conversion into food and feed, focusing on challenges such as the contamination of food/feed products with bacteria from the insect gut and the risk of rapidly spreading pathogens and parasites. We propose solutions to prevent the outbreak of infections among farmed insects without reliance on antibiotics. Transgenerational immune priming and probiotic bacteria may provide alternative strategies for sustainable insect farming.

“…Thus, biological control may provide an alternative way of managing D. fovealis (Zawadneak et al, 2016). However, in the development of a biological control program of any agricultural pest, the fi rst step is to obtain a good understanding of the basic biology of the target species and how it can be effi ciently reared in the laboratory (Sørensen et al, 2012). The rearing of a pest could be optimized by developing an artifi cial diet (Cohen, 2005;Parra, 2012;Sørensen et al, 2012).…”

The rearing of a pest could be optimized by developing an artifi cial diet (Cohen, 2005;Parra, 2012;Sørensen et al, 2012). The main advantage of using artifi cial diets instead of natural foods is the continuous supply of laboratory-reared insects of known quality (Sing, 1983).…”
