“…The control of the causal fungal pathogens is therefore critical to extend the shelf‐life of these fresh products (Arah, Amaglo, Kumah, & Ofori, 2015; Prusky, 2011). Despite the efficacy of synthetic fungicides in the control of postharvest decay, public concerns about chemical and toxic residues in food (Belden, McMurry, Smith, & Reilley, 2010; Gonçalves et al., 2019; Liu, Yamdeu, Gong, & Orfila, 2020; Mebdoua, 2018) and the increase in drug‐resistant strains of many pathogens (Zuccolo et al., 2019) indicate the need for development of new strategies. Over the last few decades, there has been an increasing interest in the study of postharvest control methods that make use of natural resources (Ebrahimzadeh & Abrinbana, 2019; Guimarães, Abrunhosa, Pastrana, & Cerqueira, 2018; Liu et al., 2019; Liu et al., 2020; Palou, Smilanick, & Droby, 2008; Souza, Yuk, Khoo, & Zhou, 2015; Talibi, Boubaker, Boudyach, & Ait Ben Aoumar, 2014).…”

Consumers are increasingly aware of the importance of regular consumption of fresh fruit in their diet. Since fresh fruit are highly sensitive to postharvest decay, several investigations focused on the study natural compounds alternative to synthetic fungicides, to extend their shelf life. A long list of studies reported the effectiveness of the natural biopolymer chitosan in control of postharvest diseases of fresh fruit. However, these findings remain controversial, with many mixed claims in the literature. In this work, we used random‐effects meta‐analysis to investigate the effects of 1% chitosan on (a) postharvest decay incidence; (b) mycelium growth of fungal pathogens Botrytis cinerea, Penicillium spp., Colletotrichum spp. and Alternaria spp.; and (c) phenylalanine ammonia‐lyase, chitinase and β‐1,3‐glucanase activities. Chitosan significantly reduced postharvest disease incidence (mean difference [MD], −30.22; p < 0.00001) and in vitro mycelium growth (MD, −54.32; p < 0.00001). For host defense responses, there were significantly increased activities of β‐1,3‐glucanase (MD, 115.06; p = 0.003) and chitinase (MD, 75.95; p < 0.0002). This systematic review contributes to confirm the multiple mechanisms of mechanisms of action of chitosan, which has unique properties in the natural compound panorama. Chitosan thus represents a model plant protection biopolymer for sustainable control of postharvest decay of fresh fruit.

“…Tephritid fruit flies in cucurbit production systems are usually controlled by chemical insecticides (Dhillion et al 2005), which have negative effects on human, animal, and environmental health, including pollinators, and may cause the development of insecticide resistance (Cloyd and Bethke 2015, Nobre et al 2019). Furthermore, misuse of insecticides may lead to surpassing allowed residue limits and raising trade challenges (Badii et al 2015, Mebdoua 2018). To reduce reliance on chemical pesticides, integrated pest management (IPM) approaches are being researched and deployed for Tephritid fruit fly control in Africa, largely on mango, Mangifera indica Linnaeus (Sapindales: Anacardiaceae) (Korir et al 2015, Muriithi et al 2016, 2020).…”

Sustainable production of pumpkin (Cucurbita maxima Duchesne) partly relies on integrated pest management (IPM) and pollination services. A farmer-managed field study was carried out in Yatta and Masinga Sub-Counties of Machakos County, Kenya, to determine the effectiveness of a recommended IPM package and its interaction with stingless bee colonies (Hypotrigona sp.) for pollinator supplementation (PS). The IPM package comprised Lynfield traps with cuelure laced with the organophosphate malathion, sprays of Metarhizium anisopliae (Mechnikoff) Sorokin isolate ICIPE 69, the most widely used fungal biopesticide in sub-Saharan Africa, and protein baits incorporating spinosad. Four treatments—IPM, PS, integrated pest and pollinator management (which combined IPM and PS), and control—were replicated 4 times. The experiment was conducted in 600 m2 farms in 2 normalized difference vegetation index (NDVI) classes during 2 growing seasons (October 2019–March 2020 and March–July 2020). Fruits showing signs of infestation were incubated for emergence, fruit fly trap catches were counted weekly, and physiologically mature fruits were harvested. There was no effect of IPM, PS, and NDVI on yield across seasons. This study revealed no synergistic effect between IPM and PS in suppressing Tephritid fruit fly population densities and damage. Hypotrigona sp. is not an efficient pollinator of pumpkin. Therefore, we recommend testing other African stingless bees in pumpkin production systems for better pollination services and improved yields.

Pesticides are chemical products are used to protect crops to prevent or eliminate undesirable organisms. Pesticides can contaminate continental waters, air, soil and food products. The presence of pesticide residues must therefore be monitored in water and food using sensitive, reliable and broad-spectrum analytical methods, as there is a huge variety of pesticides. Biosensors are one of the screening methods with great potential for detecting residues below the maximum residue limits. The different sensing principles of enzymatic biosensors for pesticide analysis will be described. This review highlights the great potential of colorimetric, enzymatic biosensors for detecting pesticide residues in water and food. Moreover the development of dual colorimetric and fluorimetric sensors during the past years is presented. These methods are most often based on the enzyme acetylcholinesterase, whose activity is inhibited by pesticides. The different approaches used in the development of these biosensors will be detailed, based on different chemical substrates, fluorophores and nanomaterials. The advantages and disadvantages of each approach will be discussed. Finally, the development prospects for improving these biosensors will be presented.
