Toxicity of insecticidal plant oils on the larval and adult stages of a major malaria vector (Anopheles gambiae Giles 1920).

Despite increasing reports and concerns about the development of resistance to public-health insecticides in malaria vectors, significant progress has been made in the search for alternative strategies to disrupt the disease transmission cycle by targeting insect vectors and thus sustaining vector management. The use of insecticidal plants is a strategy that can be employed and this study investigates the toxicity potential of insecticidal plant oils shortlisted in an ethnobotanical survey on Anopheles gambiae larvae and adult stages. The shortlisted plants parts, the leaves of Hyptis suaveolens, Ocimum gratissimum, Nicotiana tabacum, Ageratum conyzoides, and Citrus sinensis fruit-peel were collected and extracted using a Clevenger apparatus.

Multiple insecticide resistance mechanisms in urban population of Anopheles coluzzii (Diptera: culicidae) from Lagos, South-West Nigeria.

Malaria is a major public health challenge in Africa with Nigeria accounting for the highest burden of the disease in the world. Vector control has proved to be a highly effective component of malaria control, however, the development and spread of insecticide resistance in major vectors of malaria have been a major challenge. This study assessed resistance mechanisms in Anopheles coluzzii populations from Kosofe, Lagos mainland and Ojo Local Government Areas in Lagos, Nigeria where An.

Outcome of capacity building intervention for malaria vector surveillance, control and research in Nigerian higher institutions.

Background: Despite the availability of effective malaria vector control intervention tools, implementation of control programmes in Nigeria is challenged by inadequate entomological surveillance data. This study was designed to assess and build the existing capacity for malaria vector surveillance, control and research (MVSC&R) in Nigerian institutions.

Methods: Application call to select qualified candidates for the capacity building (CB) intervention training programme was advertised in a widely read newspaper and online platforms of national and international professional bodies.
