Resumen

VALENCIA V, Luis. NATURAL ENEMIES OF ALEURODICUS JULEIKAE BONDAR (HEMIPTERA: ALEYRODIDAE) IN AN URBAN ENVIRONMENT OF LIMA, PERÚ. Idesia [online]. 2009, vol.27, n.2, pp.79-89. ISSN 0718-3429.  http://dx.doi.org/10.4067/S0718-34292009000200010.

This research was carried out in an urban environment of Santiago de Surco, district of Lima, Peru. The experimental area consisted of a circle 3 km in diameter approximately, at the Monterrico Chico suburb. The research was implemented between January 2006 and April 2009. Fifteen species of fruit and ornamental trees belonging to 12 plant families growing in parks and gardens of the experimental area, were sampled. Field observations every 30 days and collection of adults and immature stages of Aleurodicus juleikae natural enemies, were made. Later, the immature stages were conditioned in Petri dishes until adult recovery. Rearing results were later matched with field observations. In this environment it was found that A. juleikae populations were regulated by four species of predators: Chrysoperla sp., Ceraeochrysa sp. (Neuroptera: Chrysopidae), Toxomerus sp. (Diptera: Syrphidae), Nephaspis sp. (Coleoptera: Coccinellidae), and a parasitoid Encarsia sp. near to dispersa. Natural enemies were more abundant in some host plants than others, irrespective of the size of the prey. The results obtained suggest that Nephaspis sp. and Encarsia near to dispersa should be considered in integrated pest management programs for the control of A. juleikae.

Palabras clave : Aleorodicus juleikae; natural enemies; Nephaspis sp.; Encarsia sp..
