Laboratory Evaluation of Residual Efficacy of Actellic 300 CS (Pirimiphos-Methyl) and K-Othrine WG 250 (Deltamethrin) on Different Indoor Surfaces.

The nature and type of local indoor resting wall surfaces to certain level influences the residual bio-efficacy of insecticides used in indoor residual spraying programs. Knockdown and mortality effects of an organophosphate Actellic 300 CS and pyrethroid K-Othrine WG 250 insecticides on the field-collected were assessed bimonthly from July to November 2014, using World Health Organization (WHO) cones bioassay test. Knockdown and mortality rates were subjected to statistical analysis using χ and Student tests.

Species composition and temporal distribution of mosquito populations in Ibadan, Southwestern Nigeria.

Nigeria has a high burden of vector borne diseases such as malaria and lymphatic filariasis (LF). This study aimed to determine the species composition of mosquitoes in Ibadan, Southwest Nigeria as well as determine their role in malaria and LF transmission. Adult mosquitoes were collected by Pyrethrum Spray Catch (PSC) and identified and graded according to their abdominal conditions.
