Diatraea flavipennella (Box) (Lepidoptera, Crambidae) is one of the most destructive pests in sugarcane plantations in the Northeast Region of Brazil. Developmental characteristics and parasitism potential of the egg parasitoids Telenomus alecto Crawford (Hymenoptera, Scelionidae) and Trichogramma galloi Zucchi (Hymenoptera, Trichogrammatidae) were compared with the aim of selecting a suitable species for biological control of D. flavipennella. Both T. alecto and T. galloi developed well and were readily adapted to D. flavipennella eggs as host. Although, T. galloi presented higher viability, with more adults emerging per host egg and higher sex ratio, the developmental period (egg-adult) was shorter in T. alecto and female longevity was extended.

Abstract Pest populations in a given agroecosystem may be influenced by several abiotic and biotic variables, including the host plant cultivar. We compared the population fluctuation of pest mites in twenty citrus scion cultivars grafted on Rangpur lime (Citrus limonia). Adults of citrus rust mite Phyllocoptruta oleivora (Acari: Eriophyidae), Texas citrus mite Eutetranychus banksi and Tetranychus mexicanus (Acari: Tetranychidae) were monthly counted in each scion cultivar from April 2011 to February 2013 in Sergipe state, northeastern Brazil. Larger E. banksi population peak was recorded on sweet orange 'Valência Montemorellos' in February 2012 compared to the other cultivars and larger populations of T. mexicanus were found on sweet orange 'Lima' in... |
