The Impact

Culex pipiens complexes play an important role in the transmission of a wide range of pathogens that infect humans, including viruses and filarial worms, as well as pathogens of wildlife, such as the avian malaria parasite (Plasmodium spp.). Numerous biotic and abiotic stresses influence vector-borne pathogen transmission directly, through changes in vector density, or indirectly by changing vector immunocompetence, lifespan, or reproductive potential. Among these stresses, mosquito exposure to sublethal doses of pesticides could have important consequences. In addition to being exposed to pollutants in aquatic breeding sites, mosquitoes can also be exposed to chemicals as adults through their diet (plant nectar). In this study, we explored the impact of mosquito exposure at the larval and adult stages to one of the most commonly used pesticides, imidacloprid, a chemical belonging to the class of the neonicotinoids, on a set of life history traits ranging from development time to fecundity. We also studied the impact of this pesticide on the susceptibility of mosquitoes to infection by the avian malaria parasite, Plasmodium relictum. Surprisingly, we observed no effects of imidacloprid on any of the parameters examined. This result highlights the fact that Culex pipiens mosquitoes do not appear to be susceptible to imidacloprid when exposure doses are close to those measured in the field.

Avian Malaria Parasite

The plasma of adult chickens, when injected into young chicks or chick embryos infected with Plasmodium lophurae, lessened the parasitemia. The substances responsible for this effect were inactivated or removed by the heating of adult chicken plasma for ½ hour at 65°C., followed by centrifugation to remove the coagulated material; but they were not affected by heating for ½ hour at 56°C. The active materials were present in the euglobulin fraction of hen plasma. In similar experiments with ducks, the plasma from each of a series of adult ducks was tested for its effect on the course of infection in young ducklings. The adult ducks were then inoculated with a large dose of parasites. There was a positive correlation between the effectiveness of a plasma in lessening the parasitemia of ducklings treated with it and the resistance on infection exhibited by the duck from which the plasma had been obtained. More than half of the adult female ducks with an active ovary which were tested, but only one of the males, had effective plasmas and also showed relative resistance to the infection.
