Pepper production in Cameroon faces many constraints, including arthropods, which occupy one of the most important places. This study was conducted with the aim of gathering information on the entomofauna of peppers for better decision-making on control methods. To achieve this, an inventory of arthropods in 4 localities in the Menoua pepper production basins was carried out on the "Simbad, "Tibesti" and "Ylusse" varieties. Insects captured weekly using an entomological net and a mouth aspirator were identified in the Agricultural Zoology Laboratory at the University of Dschang. The results showed that insects associated to peppers varied in number and diversity from one locality to another. A total of 4003 Insecta and Arachnida were captured. The Insecta class has 9 orders (Coleoptera, Diptera, Hemiptera, Hymenoptera, Thysanoptera, Lepidoptera, Odonata, and Orthoptera) of 85 families. The Order of the Hemiptera is the most representative in terms of individuals (1627) and that of the Diptera the most representative in number of families (27). Pearson's X-squared test shows a significant dependence between different orders of arthropods and the 3 varieties of peppers. The "Simbad" variety proved to be the most sensitive with 48.31%. Although most of these insects are pepper pests, there have been some pollinators, predators and parasitoids. The data collected provide a preliminary basis for any biological or integrated pest management against Capsicum annuum pests in Menoua-Cameroon.
A new Phytolyma species from Cameroon is described. Phytolyma tchuentei sp.n. is similar to P. minuta Hollis but antenna, male and female terminalia are different from the four described African Phytolyma species. P. tchuentei sp.n. develops on Morus mesozygia (Moraceae). Unlike the other Phytolyma species, the new species does not cause galls on leaves and buds of its host.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
