“…Since then, a whole lot of evolution has happened in this field of research, with intraspecific and interspecific interactions pursued through pheromone and allelochemicals isolation (Camps and Coll 1993;Regnier and Law 1968). Various semiochemicals are currently used in IPM, specifically for monitoring, mass trapping, mating disruption, (El-Ghany 2019; Jones 2014), or most recently as deterrents (host marking pheromones) (Cheseto et al 2018). Semiochemicals offer huge benefits to both human, animal, and environmental health if used properly.…”

Important alien and potential native invasive insect pests of key fruit trees in Sub-Saharan Africa: advances in sustainable pre- and post-harvest management approaches

Fruit production in Sub-Saharan Africa is of paramount importance both socially and economically. Millions of farmers derive livelihoods from mango, avocado, citrus, cashew, and coconut farming, but native and alien invasive species constrain production The region’s capacity to contain invasives is weak due to the absence of national and institutional support systems for early detection, containment, eradication, or management of the pests. Climate change is expected to play a huge role in the influx of more alien invasive species and the shift of ecological requirements of some native species. Though a fair share of pre-and post-management pest management techniques for several insect pests has been developed, adoption and adaptation of the options are limited. Data on economic and social implications are largely lacking, making it challenging to implement informed policy decisions. The existence of the “Strategy for Managing Invasive Species in Africa 2021–2030” promises a paradigm shift in the management of invasives, from reactive thinking to coordinated proactive approaches. The uncoordinated deployment of management measures in the region and the lack of funding, play a negative role in managing the pests effectively. Prospects for enhanced future research are wide, and efforts are currently being channeled to Area-Wide-Integrated Pest Management in a bottom-up approach with stakeholders owning the process. Participatory development of technologies is also taking centre stage, paving the way for increased adoption and adaptation. Postharvest technologies promise to provide the adequate phytosanitary assurance required by countries importing fruit from Sub-Saharan Africa.

“…Although HMPs are predominantly recognised by individuals of the same species [ 29 , 129 ], interspecific perception of HMPs has also been described in tephritids. Cross-recognition has been demonstrated among species of the Rhagoletis [ 130 , 131 ], Anastrepha [ 132 ] and Ceratitis genera [ 33 , 34 ]. The host-marking behaviour may display different features even among species of the same genus.…”

“…Recently, the HMP of C. cosyra and C. rosa have been isolated and both chemical structures have been determined [ 33 , 34 ]. The C. cosyra and C. rosa HMP identified are the tripeptide glutathione (GSH) (consisting of glycine, cysteine, and GA [ 33 ]), and GA [ 34 ] , respectively. Interestingly, GSH and GA levels were 5–10 and 10–20 times higher in the faecal matter than in the ovipositor or haemolymph extracts of the respective females.…”

“…Its function is to affect the oviposition behaviour of conspecifics in a way that subsequent eggs are not deposited in their already utilised resource, thus reducing the time spent on the already exploited resource and the competition for limited host resources, with advantages for both the marker and the seeker [ 29 ]. The HMP can be synthetized by female fruit flies in the form of a complex molecule [ 30 , 31 , 32 ] or a simple compound [ 33 , 34 , 35 ]. The receptors located in the tarsi and mouthparts of females searching for an oviposition site allow the detection of HMPs [ 29 , 36 , 37 ].…”

The Dipteran family Tephritidae (true fruit flies) comprises more than 5000 species classified in 500 genera distributed worldwide. Tephritidae include devastating agricultural pests and highly invasive species whose spread is currently facilitated by globalization, international trade and human mobility. The ability to identify and exploit a wide range of host plants for oviposition, as well as effective and diversified reproductive strategies, are among the key features supporting tephritid biological success. Intraspecific communication involves the exchange of a complex set of sensory cues that are species- and sex-specific. Chemical signals, which are standing out in tephritid communication, comprise long-distance pheromones emitted by one or both sexes, cuticular hydrocarbons with limited volatility deposited on the surrounding substrate or on the insect body regulating medium- to short-distance communication, and host-marking compounds deposited on the fruit after oviposition. In this review, the current knowledge on tephritid chemical communication was analysed with a special emphasis on fruit fly pest species belonging to the Anastrepha, Bactrocera, Ceratitis, and Rhagoletis genera. The multidisciplinary approaches adopted for characterising tephritid semiochemicals, and the real-world applications and challenges for Integrated Pest Management (IPM) and biological control strategies are critically discussed. Future perspectives for targeted research on fruit fly chemical communication are highlighted.

“…Fruit flies store a substantial amount of HMP in the midgut, which can either be released after egg laying through the ovipositor or with the faecal matter (Prokopy, Averill, et al, 1982; Scolari et al, 2021). Raw faeces material has been successfully used to deter oviposition behaviour in a few fruit fly species in both laboratory and field conditions (Aluja et al, 2009; Aluja & Boller, 1992; Cheseto et al, 2018; Kachigamba et al, 2012; Katsoyannos & Boller, 1980). The use of HMP as a potential management tool for fruit flies' control presents a sustainable alternative to conventional pesticides used today (Aluja et al, 2009; Aluja & Boller, 1992; Birke et al, 2020; Katsoyannos & Boller, 1980).…”

Following oviposition, females of many fruit flies deposit on the fruit surface a host‐marking pheromone (HMP) that can deter oviposition by conspecifics and heterospecifics, thereby minimizing overexploitation of hosts. We describe the oviposition behaviour of two economically important fruit flies (Anastrepha fraterculus and Ceratitis capitata) in agar spheres marked with methanolic and aqueous faeces extracts that contain the HMP. Laboratory bioassays revealed that A. fraterculus mated female produces an HMP that can be extracted from faeces, and causes a significant reduction in fruit infestation by both conspecifics and heterospecifics (cross‐recognition). Furthermore, mated female faeces extract contains higher amounts of methyl (9E)‐hexadecenoate, methyl hexadecanoate, methyl linoleate and methyl (9Z)‐octadecenoate than male faeces extract. Our results provide evidence for the potential use of this ovipositional deterrent in crop protection and pest management programmes for A. fraterculus and C. capitata.
