tesis doctoral
The main objective of this thesis was to quantify the number and identify the types and other characteristics of pesticide containers and to determine the amount (weight and volume) of the toxic waste contained in them for use in vegetable agroecosystems Monsefú ( Callancas, Monsefú) and Reque, Province of Chiclayo, Lambayeque Region from September to December 2009. Identifies three sampling areas: Callancas, Reque Monsefú and were evaluated in 62, 95, and 183 sampling units (MU) respectively. The UM was 2500 m2., In which were collected and used containers of pesticides to the farmers surveyed. UM 340 (85 hectares), were collected 413 containers used, averaging 4.54 packaging/ha. The containers were the most frequent 1000 g and 1000 ml capacity. The 88.14% of the plastic containers were collected, with the High Density Polyethylene - HDPE predominant. The mean residue weight and volu...

El maíz amarillo duro (Zea mays L.) es un cultivo de importancia económica para el departamento de Lambayeque, siendo la familia Chrysopidae (Insecta: Neuroptera) utilizado como predador de plagas de larvas de lepidópteros como Spodoptera frugiperda. La fenología según el SENAMHI, lo divide en cuatro etapas Siembra – emergencia (I etapa), Emergencia – panoja (II etapa), Panoja – espiga (III etapa), y Espiga – maduración (IV etapa), en cada etapa la riqueza y diversidad de Crisópidos varía, por lo que la liberación adecuada de este controlador biológico dependería de cada etapa, por lo que el objetivo de estudio fue comparar los índices de similitud de Morisita obtenidos por cada periodo vegetativo. Las especies colectadas fueron, Chrysoperla carnea, Chrysoperla externa, Chrysoperla assoralis, Cereochrysa cincta, Cereochrysa sp. Leucochrysa sp. Entre las cuales Chrysop...

Se colectaron muestras de tierra de diferentes cultivos de maíz del distrito de Monsefú y cultivos de mango del distrito de Motupe, aislándose dos cepas una M2 del distrito de Monsefú y otra MH del distrito de Motupe, ambas fueron recuperadas y multiplicadas en larvas de Gallería melonella, conservándose a temperatura ambiente en el laboratorio de control biológico de la Universidad Nacional Pedro Ruiz Gallo - Lambayeque.

Background Entomopathogenic nematodes (EPN) are used as a biological control agent for diferent insect pests in agriculture. The genera Heterorhabditis and Steinernema are the most used commercially. For an EPN species to be used as a biological controller, it is necessary to know its ecological aspects, including reproductive potential, movement capacity, and mean lethal concentration (LC50). These aspects were evaluated in three EPN strains isolated in Galleria mellonella larvae collected in the Lambayeque-Peru region, to determine if they are promising as biological controllers. The strains of EPN studied are Heterorhabditis sp. (PC9 strain), H. bacteriophora Poinar (PM10 strain), and Steinernema diaprepesi Nguyen y Duncan (SV19 strain). Results Heterorhabditis sp. (PC9 strain) and H. bacteriophora (PM10 strain) had high production of infective juveniles (IJs): 217.750 and 186.800, re...

Objective: Identification of pest insects, predators and phytopathogenic fungi of the “loche” Cucurbita moschata Duch (Cucurbitaceae) crop in Ucupe, Mocupe-Lambayeque. Methods: random sampling, five sampling points were taken per crop. Results: Bemisia tabaci attacks the milk crop, it was found causing scratches on the underside of the leaves. Thrips tabaci is a pest that locates on the youngest shoots. Diaphania nitidalis, this is the pest that causes the most damage, since it is a borer insect that attacks fruit, stems, and flowers. Among the controllers: Chrysoperla externa, Rhinacloa sp., Neides sp., Orius sp. and Cicloneda sanguinea. Among the phytopathogenic fungi found Cunninghamella spp., Colletotrichium sp., Memnoniella sp., Verticillium sp., Cladosporium sp. and Stemphylium sp.
