Question

A newly discovered strain of anopheles gambiae, a mosquito, is found to be resistant to a particular insecticide due to a new allele at a specific locus. When individuals of this strain are mated with individuals of an insecticide-susceptible strain of a. Gambiae, all offspring are susceptible. If males and females of these susceptible offspring are then mated with one another, what proportion of offspring do you expect will be resistant?.

Answer 1

0.25

Proportion of offspring we expect will be resistant is 0.25

What is meant by specific loci?

A locus is a fixed, specific location on a chromosome where a certain gene or genetic marker is found in genetics.

• We looked at any connections that might exist between the usage of insecticides in agriculture and the development of insecticide resistance.
• Anopheles gambiae strains that are widely recognized and replicated mosquito larval environments were used in bioassays.
• Insecticide-used sites, sites where they had not been used for two months, and sites where they had not been used at all were all sampled for soil in Benin's vegetable-growing regions.
• When exposed to soil that had previously been treated with insecticides, pyrethroid-susceptible strains' pupation and emergence rates were extremely low.
• Pupation and emergence rates were much greater in strains with the kdr mutation alone or in combination with the Ace-1 mutation.
• In general, strains with the kdr mutation outlived those without it more frequently.
• Despite the observational nature of our study, we give indirect evidence that agricultural soils contain pesticide residues that may contribute to the development of insecticide resistance in Anopheles.
• To more effectively use the insecticide within the framework of integrated pest control programs, this element should be taken into consideration.
