Thesis (MScAgric)--Stellenbosch University, 2012.<br>ENGLISH ABSTRACT: The agricultural industry in South Africa is dominated by the use of insecticides. Producers rely heavily on chemicals that cause increased risk to health, the environment and ecology, rapid resistance development in key insect pests and pesticide residues on crops. The increased concern regarding the impact of these pest management practices on the environment and alternative pest management strategies are being investigated. Entomopathogenic nematodes (EPNs) have been identified as being promising biological control agent

Heterorhabditis é um gênero de nematoides entomopatogênicos, simbiontes de bactérias do gênero Photorhabdus. Juntos, infectam e matam artrópodes. A linhagem LPP7 de H. baujardi foi isolada na cidade de Monte Negro (RO). A vitelogênese compreende o acúmulo de reservas dentro do ovócito em crescimento. A vitelogenina é uma lipoproteína transportadora de lipídeos para o ovócito, formando o vitelo. Sequenciamos um fragmento de 800pb do gene vit-6 de LPP7, codificante do fim do polipeptídeo homólogo ao VT3 de O. tipulae ou ao YP88 de C. elegans.

Soil nematodes are highly responsive to, and display a wide variety of responses to changing environmental conditions, making them ideal models for the study of organismal interactions with their environment.
