Abstract

espanolLos crisopidos (Insecta: Neuroptera) son controladores biologicos en cultivos de importancia economica, se desconoce las especies presentes en el departamento de Lambayeque. El objetivo fue determinar las especies de crisopidos en zonas maiceras del departamento de Lambayeque, permitiendo un correcto Manejo Integrado de Plagas en el maiz amarillo duro para la Costa Norte del Peru. Se colectaron adultos de crisopidos en cinco hectareas de maiz amarillo duro de los distritos de Jayanca, Pitipo y Lagunas; mediante muestreo directo y atrayente de luz. En 18 muestreos se colectaron un total de 558 crisopas adultas. Las especies identificadas en fueron: Chrysoperla externa Hagen, C. carnea Stephens, C. assoralis Banks, Ceraeochrysa cincta Schneider, Ceraeochrysa cubana Hagen, Ceraeochrysa valida Banks, Ceraeochrysa sp., Leucochrysa sp. y Plesiochrysa paessleri Navas. Las especies dominantes fueron Chrysoperla externa y Ceraeochrysa cincta con abundancia relativa de 31,91% y 26,6% respectivamente, valores que superan a S (inverso de riqueza) de 14,28% durante la colecta directa de horario diurno, en horario nocturno Chrysoperla carnea tambien presenta dominancia. Ceraeochrysa cincta es la especie con mayor presencia en los tres distritos, se le considera dominante, por sobrepasar 1/S en todos los muestreos realizados. EnglishChrysopids (Insecta: Neuroptera) are biological controllers in economically important crops, species present in the department of Lambayeque are unknown. The objective was to determine the species of chrysopids in maize areas of the department of Lambayeque, allowing a correct Integrated Management of Pests in hard yellow corn for the North Coast of Peru. Chrysopid adults were collected on five hectares of hard yellow corn from the districts of Jayanca, Pitipo and Lagunas;by direct sampling and light attractant. 558adult chrysopids were collected in 18 samples. The species identified in were: Chrysoperla externaHagen, C. carneaStephens, C. assoralisBanks, Ceraeochrysa cinctaSchneider, Ceraeochrysa cubanaHagen, Ceraeochrysa validaBanks, Ceraeochrysasp., Leucochrysasp. and Plesiochrysa paessleriNavas. The dominant species were Chrysoperla externaand Ceraeochrysa cinctawith a relative abundance of 31.91% and 26.6% respectively, values that exceed S (inverse of wealth) of 14.28% during the direct collection of daytime hours, at nighttime Chrysoperla carneaalso presents dominance. Ceraeochrysa cinctais the species with the greatest presence in the three districts, it is considered dominant, for exceeding 1/S in all the samples taken.
