Fungal Pathogens on Some Lepidopteran Forest Pests in Bulgaria
Original language description
Fungal entomopathogens found in natural populations of 7 lepidopteran forest pests were isolated and identified. Beauveria bassiana was established as a dominating species followed by Fusarium sp. and Aspergillus sp. The pine processionary moth Thaumetopoea pityocampa was the most affected by B. bassiana -66.7% of the analysed dead larvae of the pest. The occurrence of B. bassiana in Malacosorna neustria, Tortrix viridana and Melitaea didyma is the first record in Bulgaria. Relative susceptibility of first-second instar Lymantria dispar larvae was estimated to three B. bassiana and one Metarhizium anisopliae isolate and susceptibility of third instars - to seven B. bassiana and one M anisopliae isolate. The bioassays showed that L. dispar larvae were tolerant to mycoses caused by the tested B. bassiana isolates and M anisopliae. M anisopliae isolate caused mycosis to first-second instar larvae with the highest lethal effect 56.67% +/- 4.84 and B. bassiana isolates 561Bb and 575Bb to th
