El objetivo de este estudio fue evaluar la patogenicidad de los nematodos, Heterorhabditis sp. (CPVG13) y Steinernema spp. (CPVC12, CPVC13) sobre el salivazo, Aeneolamia albofasciata y determinar su persistencia en suelo de tres ingenios azucareros Potrero, Constancia y Motzorongo, en el estado de Veracruz. En el primer experimento la patogenicidad de los nematodos entomopatógenos se evaluó en ninfas de mosca pinta, Aeneolamia albofaciata de 3° y 4° instar, se aplicaron 120 JI/ninfa sobre cajas con seis cavidades, cubiertas previamente con papel filtro, cada cavidad contenía un estolón de pasto (Cynodon sp.) y una ninfa por cavidad. En el segundo experimento, se evaluó la persistencia de los nematodos entomopatógenos (NEPs) en suelo, el experimento tuvo... |

Spodoptera frugiperda (Smith, 1797) (Lepidoptera: Noctuidae) is considered to be the main pest of maize crops in Brazil. Entomopathogenic nematodes (EPN) may be used to control this pest and exhibit different, unique abilities to search for their hosts. The movement of EPN in relation to S. frugiperda was evaluated. To test for horizontal movement, a styrofoam enclosure filled with sand was divided into segments, nematodes were placed at the entrance to the enclosure and a larva was placed at the end of each division. The same approach was used to evaluate vertical movement; however, PVC pipes were used in this case. In general, the mortality was inversely proportional to the initial distance between host and nematodes. In the vertical displacement test,... |

Abstract Black fly is a pest of Asian origin that causes direct and indirect damages to citrus, damaging the development and production of plants. For the development of efficient management strategies of the pest, the integration of control methods is necessary, and biological control is the most appropriate. Among the agents that can be used, entomopathogenic fungi are considered one of the most important and wide-ranging use. This work investigated the occurrence of Purpureocillium lilacinum (Thom.) Luangsa-ard et al. (= Paecilomyces lilacinus), attackingnymphs of citrus black fly, Aleurocanthus woglumi Ashby (Hemiptera: Aleyrodidae). The fungus was isolated from infected Black fly nymphs, present on Citrus spp leaves in the municipality of Morros,... |
