“…Histopathological changes in the intestine of C. pipiens are similar to those observed by Kellen et al (1965) on Culex tarsalised with Bacillus sphaericus, including cell degeneration of the anterior stomach and vacuolation, which invades cells during all stages of the poisoning of Culex (Figure 6). …”

The Culicidae are biting insects that are most harmful to people. They are almost all blood-suckers, and are responsible for the spread of many important diseases such as malaria, yellow fever and elephantiasis. Entomopathogenic microorganisms occupy an important place among the alternative methods of fighting against pests insect. The fungus, Beauveria bassiana is an entomopathogenic agent naturally present in the ecosystems and offers a very interesting potential for controlling populations of mosquitoes. Our study aims at showing the 4 th stage larvae histological changes of the domestic mosquito Culex pipiens, treated with the entomopathogenic fungus B. bassiana in suspension which corresponds to a dose of 10 7 spore/mL. In fact, after developing the individuals in the fungal solution, histological study was carried out on the following parts; cuticle, intestine, adipose tissue and hemolymph. The histological studies showed many alterations and malformation in the treated 4 th instar larvae body and tissues. The infection affected the different parts of the body, especially the cuticle, the adipose cells, and midgut, in addition to the development and the colonization of B. bassiana inside tissues. The application of B. bassiana on the cuticle of the larvae was dependent on an apparent disturbance in the structure of the cuticle or the degeneration of its different parts. The fungus infection does not stop at the level of the body walls, so it even goes to adipose tissue, epidermal cells and intestine. Based on these results, B. bassiana could be suggested as suitable biocontrol agent against C. pipiens.

“…However, the strain discovered (B. sphaericus K) did not have a very effective activity, which limited its use (Kellen et al, 1965). Currently, several toxic strains are known, and most studies utilize strains 1593 and 2362, respectively isolated in Indonesia (Singer, 1973) and Nigeria (Weiser, 1984).…”

“…The second important event was the discovery, in 1964, of a mosquitocidal strain of Bacillus sphaericus (B.s) (Kellen & Meyers 1964) followed by the identification of several more active strains and by the isolation of a new variety of B. thuringiensis (B.t) (Goldberg & Margalit 1977) designated as B. t. israelensis (B.t.i) (de Barjac 1978), toxic to mosquito and black flies larvae. Highly toxic to the target organisms, these spore forming bacteria are able to be mass produced, stored, easily transported and applied.…”
