Abstract Background The pine processionary moth, Thaumetopoea wilkinsoni Tams, 1926 (Lepidoptera/Notodontidae) is one of the most harmful insects that destroys pine ecosystems by feeding on pine leaves at its larval stage. Because of its urticating setae, the insect also causes severe skin reactions to animals and humans. Instead of chemical control, eco-friendly biological control methods are preferred to combat this species. Results The purpose of this study was to evaluate the efficacy of five different Beauveria bassiana Vuill, 1912 (Hypocreales/Cordycipitaceae) isolates (TR-SM-10, TR-SM-11, TR-SM-2, TR-SK-1 and TR-D-1) and one B. pseudobassiana Rehner & Humber (Hypocreales/Cordycipitaceae) isolate (TR-SM-1) against the fourth instar larvae of T. wilkinsoni under laboratory conditions. T. wilkinsoni larvae were collected from the Ondokuz Mayıs University Kurupelit Campus in Samsun, Turkey, in 2021, and the fourth instar larvae were used in the experiment. Two ml of spray of the six fungal isolates were applied to every ten larvae at each concentration (1 × 107 and 1 × 108 conidia ml−1). The experiment was carried out in five replicates per group, and the larvae were observed for 10 days. As a result, all isolates of B. bassiana caused 100% mortality at 1 × 108 conidia ml−1 concentration. B. pseudobassiana isolate also caused 100% mortality at both concentrations. At 1 × 107 conidia ml−1 concentration, the larvae treated with the B. pseudobassiana isolate (TR-SM-1) had the lowest LT50 (2.89 days) and LT90 values (4.79 days), while the larvae treated with TR-SM-10 isolate had the highest LT50 (5.65 days) and LT90 values (9.39 days). At 1 × 108 conidia ml−1 concentration, the larvae treated with TR-SK-1 isolate had the lowest LT50 (2.89 days) and LT90 values (4.79 days), while those treated with TR-SM-10 isolate had the highest LT50 (3.95 days) and LT90 values (8.15 days). Conclusion It has been recommended that the five different isolates of B. bassiana and B. pseudobassiana isolates were virulent to T. wilkinsoni larvae and can be used for biological control of T. wilkinsoni.

Pine processionary moths, Thaumetopoea wilkinsoni Tams, 1924 and Thaumetopoea pityocampa ([Denis & Schiffermüller], 1775) (Lepidoptera: Notodontidae) are among the most destructive pine pests in Mediterranean basin. Their larvae descend to the ground from the canopy in spring for pupation and rest there until late summer. Although this is the general pattern, pupal period is a plastic feature and can be prolonged for up to several years. It is considered one of several difficulties of processionary moth management as such a plasticity provides a continuous support from the underground reservoir to the pest population. This phenomenon has been known for a long time and its discovery has been attributed to Guy Démolin; renowned INRA (France) researcher. Here, we report an unnoticed researcher, Ömer Besçeli, from Turkey who published the phenomenon of prolonged diapause in the pine processionary moth earlier.
