Abstract Background: For controlling the resistance to insects, in particular carpophagous and phyllophagous caterpillars, using chemical pesticides has led to contamination of cotton area in Benin. Facing this problem, alternative methods including the use of entomopathogenic fungi as biopesticide could be a sound measure to preserve the environment, biodiversity and ensure good quality of crops. Previous studies have revealed the insecticidal potential of the entomopathogenic Beauveria bassiana on some insect pest species. However, little is known about its effectiveness on cotton Lepidopteran pests. This review is done to learn more about B. bassina for its application in controlling cotton insect pests, especially Lepidopteran species. Main body: Different sections of the current review deal with the related description and action modes of B. bassiana against insects, multi-trophic interactions between B. bassiana and plants, arthropods, soil and other microbes, and biological control programs including B. bassiana during last decade. Advantages and constraints in applying B. bassiana and challenges in commercialization of B. bassiana-based biopesticide have been addressed. In this review, emphasis is put on the application methods and targeted insects in various studies with regard to their applicability in cotton. Conclusion: This review helps us to identify the knowledge gaps related to application of B. bassiana on cotton pest in general and especially in Lepidopteran species in Benin. This work should be supported by complementary laboratory bioassays, station and/or fields experiments for effective management of cotton Lepidopteran pests in Benin.

Background The hopeful perspective projected for crop protection and public health as a result of the introduction of chemical pesticides is now open to serious question because of an alarming increase of resistance occurring in insects, pathogens, vertebrates, and a lesser extent in * Correspondence: [email protected] 1 Laboratory of Phytotechnic, Improvement and Protection of Plants, Faculty of Agronomy, University of Parakou, BP 123, Parakou, Benin 2 International Institute of Tropical Agriculture, 08 BP 0932 Tri Postal, Cotonou, Benin Full list of author information is available at the end of the article
weeds (National Research Council [NRC] 1986). In the case of insect pests, one of the practices inducing selection of resistant crop populations is due to an overuse of same or closely related chemical insecticides (Food and Agriculture Organization [FAO] 2012). Facing this challenge, integrated pest managem
