AbstractTerrestrial molluscs (Mollusca: Gastropoda) are important economic pests worldwide, causing extensive damage to a variety of crop types, and posing a health risk to both humans and wildlife. Current knowledge indicates that there are eight nematode families that associate with molluscs as definitive hosts, including Agfidae, Alaninematidae, Alloionematidae, Angiostomatidae, Cosmocercidae, Diplogastridae, Mermithidae and Rhabditidae. To date,Phasmarhabditis hermaphrodita(Schneider, 1859) Andrássy, 1983 (Rhabditida: Rhabditidae) is the only nematode that has been developed as a biological molluscicide. The nematode, which was commercially released in 1994 by MicroBio Ltd, Littlehampton, UK (formally Becker Underwood, now BASF) under the tradename Nemaslug®, is now sold in 15 different European countries. This paper reviews nematodes isolated from molluscs, with specially detailed information on the life cycle, host range, commercialization, natural distribution, mass production and field application ofP. hermaphrodita.

The present study aims at optimization of a suitable mass production technology for growth and sporulation of the biocontrol agents Verticillium lecanii and Trichoderma harzianum. Combinations of various natural solid substrates (Rice, Maize, Arhar, Defatted Soybean, Gram) and laboratory media (SMYA, Complete media, SDA, Czapek’s Dox media ) were evaluated for growth and sporulation of V. lecanii and T. harzianum. Data on CFU, concentration of propagules, dry mycelial weight, conidia production and conidia yield were analyzed. It was observed that among the substrate types tested, the fungal strains grew better and produced high quantity of spores in Rice as growth medium after 21 days of incubation followed by Maize and Arhar. The best liquid media which supported maximum conidial production was SMYA and Complete medium. Also, rate of germination of spores as well as their viability at different aeration rates was tested. It was observed that maximum length of germ tube in minimum duration was observed in Rice as substrate. The viability percentage of the biocontrol agents produced at various aeration rates and agitation speeds showed that change in aeration and agitation did not significantly affect spore viability. Results demonstrated that the fungal species could be rapidly produced with a high conidial yield on natural solid substrates as compared to liquid media by fermentation technology.

Selection Of

<p>The relevance of biocontrol agents in plant pathology is still limited in spite of the great enthusiasm generated by research on biopesticides. Most of scientific reports are focused on selection of strains and basic biochemical studies. Priority issues as mass production formulation of biocontrol agents, toxicological and environmental safety and integration into other control strategies are not completely developed.</p><p> </p><p><strong>Desarrollo de Agentes de Biocontrol: Oportunidades y descubrimientos para sus aplicaciones prácticas</strong></p><p>Aunque el control biológico de fitopatógenos, como alternativa de control sostenible, ha despertado considerable entusiasmo en los últimos tiempos, la mayor parte de la investigación reportada hasta ahora, refleja más un interés académico que práctico desde el punto de vista de su aplicación. Es así como la mayoría de reportes hechos en la literatura científica están enfocados hacia la selección de cepas con potencial para el biocontrol y al estudio de sus mecanismos de acción. Sin embargo, temas prioritarios tales como la producción masiva, la formulación, la seguridad toxicológica y medioambiental, y la integración con otras formas de control, han presentado escaso desarrollo.</p>
