Book Description
The potato tuber moth Phthorimaea operculella (Lepidoptera: Gelechiidae) is the most important pest in potato production in the tropics and subtropics. Faced with serious and increasing problems due to the extensive use of chemical pesticides to control this pest, safer alternatives such as the use of entomopathogens are of growing interest. The research presented here focus on the efficient integration of the endemic granulovirus infecting the potato tuber moth (PoGV) as biopesticide into IPM strategies. The investigations include basic research on the granulovirus-host interaction and ecology which allows a comprehensive understanding of the system and how the system is influenced by environmental factors, and applied research to improve the virus mass propagation technique and the UV-stability of the virus. The results presented allow differentiation between conditions occurring in different agroecological regions for appropriate management of the virus.

Book Description
The pathogenicity of three local isolates of the entomopathogenic fungus Beauveria bassiana (Bals.) Vuill was evaluated on eggs of potato tuber moth P. operculella (Zeller). The three isolates were coded as the following: B (isolate from Latakia), C (isolate from ICARDA) and D (isolate from Damascus). Three concentrations 104, 105, and 106, respectively, conidia/ml were used for each isolate. Eggs in the control were sprayed by sterilized water. All tests were done under laboratory conditions of temperature 28 ± 2°C and relative humidity 40 ± 5%. Susceptibility tests showed significant differences in averages of hatching rate between the control and both isolates B and C when 1 × 106 conidia/ml was applied, with averages 18.3 and 26.6% for previous isolates respectively, in contrast to 38.3 for isolate D and 66.6% for control. Findings indicated that eggs of P. operculella seemed sensible to local isolates of B. bassiana in varying degree, but further studies are required about the efficiency of effective isolates for controlling eggs of this pest in natural conditions.
