“…The COI region has been used successfully to characterize the mite species complex [49][50][51] ; thus, we believed this type of data would aid the species identification of mites associated with cassava. Among the most important species, only a partial COI sequence for M. progressivus is available at NCBI 52 ; thus, the four haplotype COI sequences reported here constitute the first to be available through GenBank for the genera Mononychellus and Tetranychus.…”

The morphological identification of mites entails great challenges. Characteristics such as dorsal setae and aedeagus are widely used, but they show variations between populations, and the technique is time consuming and demands specialized taxonomic expertise that is difficult to access. A successful alternative has been to exploit a region of the mitochondrial cytochrome oxidase I (COI) gene to classify specimens to the species level. We analyzed the COI sequences of four mite species associated with cassava and classified them definitively by detailed morphological examinations. We then developed an identification kit based on the restriction fragment length polymorphism–polymerase chain reaction of subunit I of the COI gene focused on the three restriction enzymes AseI, MboII, and ApoI. This set of enzymes permitted the simple, accurate identification of Mononychellus caribbeanae, M. tanajoa, M. mcgregori, and Tetranychus urticae, rapidly and with few resources. This kit could be a vital tool for the surveillance and monitoring of mite pests in cassava crop protection programs in Africa, Asia, and Latin America.

“…The Cassava green spider mite, (Mononychellus progresivus) originates from South America (Mutisya et al 2016;Neuenschwander 2010). The first record of its introduction to Africa came from Uganda in 1970 (Gutierrez 1987), but its presence is now confirmed in 28 countries throughout the African BCassava Belt^(Supplementary Table S1).…”

“…The first record of its introduction to Africa came from Uganda in 1970 (Gutierrez 1987), but its presence is now confirmed in 28 countries throughout the African BCassava Belt^(Supplementary Table S1). Earlier taxonomic work by Gutierrez (1987) and recent molecular analysis (Mutisya et al 2016) has provided evidence that the different populations in Africa belong to a single biological species now designated as Mononychellus progresivus. This species has been reported to cause 30-50% yield loss locally (Matthews and Brand 2004), but reliable data on national level production losses are lacking.…”

Alien invasive insect and mite species (AIS) represent a major challenge for agriculture, food production, and biodiversity in Africa. However, the lack of awareness and appreciation of AIS threats continues to hinder the development of appropriate policies and practices for their management in sub-Saharan Africa. The objectives of this review are to (1) provide a synthesis of current and future threats to food production and the economic impacts of AIS, (2) identify challenges to their management at national and regional levels, and (3) propose a strategy for a concerted pan-African response. The review identifies a total of 16 alien invasive insect and mite pests, affecting all categories of food crops, causing combined losses in excess of US$ 1 billion annually across Africa. Various models predict that AIS threats will continue to increase due to expansion of the geographic distribution and host range of existing invasions, thus threatening the already tenuous food situation on the continent. The review also reveals that only 16.7% of the countries have adequate border control procedures, while over 66.7% do not have comprehensive AIS management strategies. Therefore, we propose development of a pan-African strategy for effectively responding to AIS threats, and achieving the continental visions of free trade and collective food security. We recommend that biosecurity be considered as a food security intervention complementing yield improvement technologies, and implemented as a core element of national and regional strategies.

“…(Hymenoptera: Formiciadae) (Aristizábal et al, 2007;Jiménez y Hernández, 2013;Hernández-Rojas et al, 2021). Alrededor de 50 especies de ácaros fitófagos han sido reportados en el cultivo de la yuca a nivel mundial en América, África y Asía, con reportes de daños y disminución del rendimiento de las raíces en un 87% y en el número de esquejes de tallo en el 82% de las plantas (Mutisya et al, 2016;Ovalle et al, 2020). Las principales familias de ácaros asociados al cultivo de la yuca son Tenuipalpidae y Tetranychidae (Bellotti y van Schoonhoven, 1978;Bellotti et al, 1979;Bellotti y Vargas, 1982;Ochoa et al, 1991a;Ovalle et al, 2020;Migeon y Dorkeld, 2022).…”

Background. Phytophagous mites of the Tetranychidae family (Prostigmata) have the potential to cause losses to the national production of cassava (Manihot esculenta Crantz), one of the important crops for food security in Panama. This is due to the high reproduction rate they have in short periods of time and the ease of dispersing in certain regions. Objetive. Report the presence of two species of phytophagous mites of the genus Mononychellus associated with cassava in the province of Coclé, Panama. Methodology. The information corresponds to a sampling of phytophagous mites associated with cassava plantations in seven locations in the province of Coclé. The study was carried out during the period from August 2023 to September 2023. In each location, five yucca plants were selected to verify the presence and damage to the foliage of phytophagous mites. For this, samples of four leaves from each plant were taken. The sampled plant material was taken to the Plant Protection Laboratory of the Divisa Agricultural Innovation Center of the Panamanian Institute of Agricultural Innovation. The samples of phytophagous mites were separated, and microslides were made to identify the species under a microscope. Results. Two species of the genus Mononychellus of the family Tetranychidae were identified as associated with damage to cassava plants. Implications: The identification of the phytophagous mite species and the damage caused in cassava is the first step to establish an integrated pest management program. Conclusions. The damages presented by the plants that are affected by the attack of the Mononychellus phytophagous mite complex in the cassava crop were identified.
