Parasitism of egg‐batches of the pine processionary moth Thaumetopoea wilkinsoni Tarns (Lep., Thaumetopoeidae) in the mountains of Lahav (Israel)

Abstract: Field investigations were carried out on the parasitism of egg‐batches of T. wilkinsoni Tarns near Lahav, Israel, in 1989. Egg‐batches were collected and studied under laboratory conditions in Hannover. For ovipositions, the host preferred the marginal, especially the southern exposed parts in the forest and in the trees. At Lahav the peak time of egg deposition durated from 13th‐23th of September. The parasitoid impact could be recorded with 38.6%. The most frequent parasitoid was Eutetrastichus servadeii (Do… Show more

“…However lower number of eggs per batch were found for the PPM in Israel [14]. The coefficients of correlation between the number of eggs per egg mass and the length of the egg mass were found to be highly significant for a given row (Table 1) which is a typical characteristic of the PPM in other countries [15,16]. Although the parasitoids exploited a large number of egg masses, their impact remain average or below average.…”

“…Ooencyrtus pityocampae (Mercet, 1921) (Hymenoptera, Chalcidoidea, Encyrtidae) constituye uno de los parasitoides más importantes asociados a las puestas de la procesionaria del pino Thaumetopoea pityocampa (Denis et Schiffermüller, 1775) (Lepidoptera, Bombycoidea, Saturniidae) (Mercet, 1921;Biliotti, 1958;Masutti, 1964;Battisti, 1989;Tiberi, 1990;Kitt & Schmidt, 1993;Mirchev et al, 1999). Aunque ocasionalmente fue considerado específico de este lepidóptero plaga (García-Fuentes, 1965), se planteaba la posibilidad de que tuviese otros hospedadores secundarios debido a su comportamiento asincrónico con respecto al ciclo biológico de su hospedador primario, aspecto sugerido inicialmente por Wilkinson (1926) y corroborado más tarde por otros autores (Masutti, 1964;Tiberi, 1978;Battisti et al, 1988;Halperin, 1990;Kitt & Schmidt, 1993).…”

“…About 10 years ago it was discovered that the eggs of one of the species in the genus Stenozygum, the variegated caper bug (CB) S. coloratum (Klug, 1845), are parasitized by Ooencyrtus pityocampae Mercet, 1921 (OP) (Hymenoptera: Encyrtidae) (Mizrachi, 2006). This parasitoid wasp is well known as one of the commonest natural enemies of the pine processionary moth (PPM) Thaumetopoea pityo campa Denis & Schiffermüller, 1775/ T. wilkinsoni Tams, 1924 (Lepidoptera: Notodontidae) species complex (Battisti, 1989;Tsankov, 1990;Kitt & Schmidt, 1993;Schmidt et al, 1999Schmidt et al, , 1997, a major pest of pine forests throughout the Mediterranean basin (Wilkinson, 1926;Battisti, 1988;Halperin, 1990;Carus, 2004;Kanat et al, 2005;Jacquet et al, 2013;Tamburini et al, 2013). Our preliminary study of OP emerging from CB eggs indicated that these eggs serve as alternative hosts for OP populations in spring and summer, when PPM eggs are absent.…”
