Seasonal variation in wing pattern of the tropical butterfly, Bicyclus dorothea across habitat in Cameroon - Dry Season in Mbalmayo

Michel Dongmo, Rachid Hanna, Timothy C. Bonebrake & Abraham Fomena
Many organisms exhibit changes in phenotypic traits as a response to seasonal environmental variation. We investigated the role of habitat in generating seasonal polyphenism in different populations of the light bush brown butterfly Bicyclus dorothea (Cramer, 1779) (Lepidoptera: Nymphalidae) in Cameroon. Butterflies were caught during the wet and dry seasons across four localities representing two distinct habitats, namely forest and ecotone (forest–savanna transition zone) over a 2-yr period (2015–2016). We found distinct variation in the...

Pathogenicity test on cocoa mirid

Mahot Hermine, Gertrude Membang, Rachid Hanna, BAD Begoude, L Bagny Beilhe & BCF Bilong
The brown cocoa mirid, Sahlbergella singularis (Hemiptera: Miridae), causes cocoa yield loss of about 30 % to 70 % in Cameroon. The pathogenicity of six indigenous isolates of Beauveria bassiana (BIITAC) and Metarhizium anisopliae (MIITAC) to the fourth and fifth nymphal stages of S. singularis was evaluated under laboratory conditions. Two methods of inoculation were tested at various conidial concentrations: (1) immersing the pod in 200 ml of the suspension for 3 min (ingestion method)...
