Biological Control Of Insects

The control of dipteran pests is highly relevant to humans due to their involvement in the transmission of serious diseases including malaria, dengue fever, Chikungunya, yellow fever, zika, and filariasis; as well as their agronomic impact on numerous crops. Many bacteria are able to produce proteins that are active against insect species. These bacteria include Bacillus thuringiensis, the most widely-studied pesticidal bacterium, which synthesizes proteins that accumulate in crystals with insecticidal properties and which has been widely used in the biological control of insects from different orders, including Lepidoptera, Coleoptera, and Diptera. In this review, we summarize all the bacterial proteins, from B. thuringiensis and other entomopathogenic bacteria, which have described insecticidal activity against dipteran pests, including species of medical and agronomic importance.

Favorable Conditions

Crop pests are the cause of economic damage in many developing countries, including Ukraine, where annual loss of crop harvest on average equals 6 million tons, valued at 840 million dollars. Pests consume grain, causing its pollution and creating favorable conditions for development of mold, which significantly decreases the food and seeding properties of grain and products of its processing. This article presents basic data on biological control and its advantages, demonstrates the variety of natural enemies of the pest beetles, which are used in biological control, analyses studies of the biological control of main crop pests and products of its processing belonging to the families Curculionidae and Tenebrionidae, and also the role of competition in  biological control. The analysis of studies on the effectiveness of different natural enemies of the main crop pest-beetles shows that the most studied parasites are Sitophilus granarius, S. zeamais, Tribolium confusum, T. castaneum, Oryzaephilus surinamensis, Rhyzopertha dominica, Acanthoscelides obtectus and Callosobruchus maculatus. Natural enemies of the rest of the species are poorly studied, and there is no data on Caulophilus latinasus, Tenebroides mauritanicus, Dermestes lardarius, Ptinus fur and Bruchidius incarnatus. The most commonly used natural enemies are Xylocoris flavipes, Anisopteromalus calandrae, the entomopathogenic fungi Metarhizium anisopliae and Beauveria bassiana, and also nematodes of the Steinernema and Heterorhabditis genera. Despite the broad spectrum of natural enemies of the main pests of the grain supply, it is necessary to further study the parasites of every species of beetle which causes economic damage. Using biological control is the most promising method against pests of crops and products of its processing, which meets the current requirements to the sanitary-ecological condition of agricultural production.

Fresh produce has been identified as an important vehicle for the transmission of foodborne pathogens. This study evaluated the behavior of vegetative cells and spores of Bacillus thuringiensis, one of the main biological control agents (BCAs) used in the world, and Salmonella enterica on spinach plants (pre-harvest) and spinach cut leaves (post-harvest) at 12°C, experimentally inoculated as single or co-cultures. The results evidenced that spray-inoculated commercial BCA containing Bacillus thuringiensis subsp. aizawai ABTS-1857 (BTa ABTS-1857) spores persisted well on spinach leaves in both pre- and post-harvest simulations. However, when BTa ABTS-1857 vegetative cells were spray-inoculated, more than 2 log reductions in the counts of B. thuringiensis were observed during 20 days pre- and 5 days post-harvest simulations, respectively. The counts of S. Montevideo on the spinach cut leaves during post-harvest storage at 12°C for 5 days remained unchanged, whereas 1 log reduction was noted during pre-harvest. Moreover, during pre-harvest simulation, when co-inoculated with BTa ABTS-1857 vegetative cells or spores, additional 0.5 or 1.0 log reductions were detected on the counts of S. Montevideo in the spinach leaves on the 10th day. These results were obtained under laboratory conditions, and further findings in longitudinal studies from farm (in the agricultural field) to retail (end of shelf life) will contribute to understanding of the role of B. thuringiensis as a BCA on growth/survival of Salmonella spp. in fresh produce.
