MARTINEZ, Ana Mabel et al. Parasitoids associated with the blackberry leafrollers Argyrotaenia montezumae Walsingham and Amorbia sp. (Lepidoptera: Tortricidae), in Michoacan. Acta Zool. Mex [online]. 2014, vol.30, n.3, pp.553-563. ISSN 2448-8445.

The leafrollers Argyrotaenia montezumae Walsingham and Amorbia sp. are tortricids associated with blackberry plants, in Michoacan, Mexico. In this study we analyzed and compared the abundance and diversity of parasitoids associated with these leafroller species in two commercial plantings in Los Reyes, Michoacan. A total of 1682 young leaves infested with leafroller larvae were collected, of these 994 specimens of four parasitoid species were obtained. The parasitoids were Chelonus sp. (41.6%), Apanteles n. sp. (34.2%), Colpoclypeus michoacanensis Sánchez & Figueroa (23.1%), and Bracon sp. (1%). Apanteles n. sp. recorded the highest percent of parasitism (26.9%) and it was also the species that appeared more frequently.

Keywords : blackberry; tortricids; natural parasitism; periodicity; biological control.
