“…Thus, papaya mealybug infestation is a significant driver in papaya yield loss in most papaya-growing regions in Tanzania. The findings of this study are in line with those reported by Kansiime et al (2020) that the papaya mealybug has emerged as a significant threat to the papaya production industry in Kenya and India.…”

“…Upon invading Kenya, yield losses were as high as 91%, resulting from the direct effect on the plants and fruits as well as loss of market due to poor yield quality (Macharia et al 2017). Three years down the line, it is estimated that Kenya loses more than USD 29.8 million annually to papaya mealybug damage with individual households losing between USD 51-740 depending on locality and market available to them (Kansiime et al 2020).…”

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.

“…Some representatives of Sterrnorhyncha cause yield losses of up to 100% [ 4 , 5 , 6 , 7 ]. For example, papaya mealybug Paracoccus marginatus Williams and Granara de Willink (Hemiptera: Pseudococcidae) infestation is a significant driver of papaya yield losses, with losses up to 75% in Tanzania [ 8 ] and 57% in Kenya [ 9 ]. Whiteflies cause complete tomato yield losses because they vector several tomato begomoviruses, including tomato golden mosaic virus, that subsequently cause great losses in yields or otherwise severely damage the crops in Brazil [ 4 , 5 , 6 , 7 ].…”

Sternorrhyncha representatives are serious pests of agriculture and forestry all over the world, primarily causing damage to woody plants. Sternorrhyncha members are vectors for the transfer of a large number of viral diseases, and subsequently, the host plant weakens. Additionally, many are inherent in the release of honeydew, on which fungal diseases develop. Today, an innovative approach is needed to create new and effective ways to control the number of these insects based on environmentally friendly insecticides. Of particular relevance to such developments is the need to take into account the large number of organisms living together with insect pests in this group, including beneficial insects. Practically without changing their location on their host plant, they adopted to be more invisible and protected due to their small size, symbiosis with ants, the ability to camouflage with a leaf, and moderately deplete plants and others, rarely leading them to death but still causing substantial economic loss in the subtropics and tropics. Due to the lack of presence in the literature, this review fills in this pesky spot by examining (on the example of distinct species from four superfamilies) the characteristic adaptations for this suborder and the chemical methods of combating these insects that allow them to survive in various environmental conditions, suggesting new and highly promising ways of using olinscides for plant protection against Sternorrhyncha members.
