A team of researchers at Federal University Dutse has discovered species of mosquitoes in Jigawa that are resistant to most insecticide-treated nets available in the state.
However, the research revealed that there are some exceptional insecticides that proved effective on all the mosquitoes
This report was contained in a press statement released by the chief information officer of the University Comrade Abdullahi Anako.
The research was sponsored by the Global Program for Malaria Control under the Surveillance for Mosquitoes Resistance against three classes of insecticides (Pyrethroids, organochlorine, and organophosphates) in the 36 states of the federation plus the Federal Capital Territory.
It was also revealed that the research was conducted at the University led by Professor M. M. Dogara
According to Prof. Dogara, the research became necessary when it became obvious that mosquitoes all over the world are developing resistance to Long-Lasting Insecticides Treated Bed Nets (LLITN) coated with pyrethroid insecticides.
He said they identified mosquito breeding sites and collected samples of lavae from six local governments in Jigawa which include Dutse, Birnin-Kudu, Kafin-Hausa, Auyo, Ringim, and Taura.
The Lead Researcher said they collect mosquito larvae from these sites and grew them to adulthood in the laboratory where they are sorted into males and females before conducting the test to see their resistance to insecticides.
He said the female anopheles’ mosquitoes with variants such as anopheles gambicae, anopheles collonzi, and anopheles arabiansis are all resistant to bed nets coated with Pyrethroids, organochlorine, and organophosphate insecticides.
According to him, the research finding shows that only Primiphosmethl insecticides kill mosquitoes 100 percent and their recommendation is that henceforth only bed nets coated with Primiphosmethl should be deployed to Jigawa.
Prof. Dogara expressed his gratitude to the Vice-Chancellor, Prof. Abdulkarim Sabo Mohammed who was instrumental in winning the N4 million research grant from the donors because institutions competed to get the grant and, in the end, FUD was chosen.
The Lead Researcher said his team consisted of six entomology investigators, technicians, and six mosquito collectors.
