Susceptibility test of female anopheles mosquitoes to ten insecticides for indoor residual spraying (IRS) baseline data collection in Northeastern Nigeria

Malaria is a major public health problem in Nigeria, accounting for about 60% of all outpatient attendances and 30% of all hospital admissions. Indoor residual spraying (IRS) was scaled up in Nigeria to supplement long lasting insecticide treated nets (LLINs) for malaria vector control. The success of IRS partly defends on the susceptibility of local anopheles mosquitoes to insecticides. The WHO standard...

Aleytrap: An instrumentation to handle adult whitefly, Bemisia tabaci, Gennadius

Whiteflies are fast flying, minute insects in the suborder Homoptera of the Hemiptera; family Aleyrodidae. They are reported to transmit viral diseases in various, economically important agricultural crops. Based on their small size (average wing spans of about 3 mm), whiteflies are difficult to count on plants or capture through insect nets and other tools. Therefore, we developed a feasible and effective method to...
