- Abstract
The distribution and infestations of termites were investigated in historic town of city Khiva Aral Sea Basin in Central Asia (historic town of Khiva, now a UNESCO cultural heritage site). We investiated The fungus Beauveria tenella (Delacrox) Siemaschko was investigated as a microbial control agent against an insect pest species, the Anacanthotermes turkestanicus (Isoptera: Hodotermitidae). B. tenella was found to cause 100% mortality of A. turkestanicus in 7 days as a wet preparation and 8 days as a dry preparation. The yield of viable fungal biomaterial was not significantly reduced when B. tenella was incubated for 15-20 days. It was established that the most effective method of the collection of fungus was its growth on PDA with the use of cellophane as a porous film, which enabled the exchange of nutrients from the agar surface and prevented growth of the fungus. After drying it is possible to obtain up to 20.7 % of the dry preparation from the crude biomass of the fungus. The tests showed that the biological effectiveness of propagules of B. tenella in experimental nests was 79.2, 78.5 and 96.5% at concentration of 0.3, 0.5 and 1.0 g per nest respectively.
