“…Application equipment itself and associated parameters can have a substantial effect on EPN field efficacy (Brusselman et al, 2010;Bullock, Pelosi, & Killer, 1999;Curran, 1992;Hayes, Fitzpatrick, & Webster, 1999;Nilsson & Gripwall, 1999;Shields et al, 1999). For example, Curran (1992) reported that trickle irrigation was inferior to surface spray or multiple injections, and Hayes et al, (1999) reported that sprinkler irrigation was inferior to a boom sprayer.…”

“…The adults feed on tender foliage of citrus and eggs are laid on mature leaves, often on the same trees on which the adults have been feeding. Neonate larvae drop to the ground and quickly burrow into the soil where they feed on roots (Bullock et al 1999). Field applications of 5 x10 6 H. bacteriophora IJs/tree resulted in P. opalus adults (76%) as compared to controls (Downing et al 1991).…”

“…Field applications of 5 x10 6 H. bacteriophora IJs/tree resulted in P. opalus adults (76%) as compared to controls (Downing et al 1991). In another experiment, two applications of S. riobrave or S. carpocapsae at 2 x 10 6 IJs/tree provided an overall 64% and 53% reduction of P. litus, respectively (Bullock et al 1999).…”

Neotropical Entomology 36(2): 161-179 (2007) Controle Microbiano de Artrópodes-Praga em Fruteiras Tropicais RESUMO -Muitos insetos e ácaros atacam fruteiras nos trópicos. O método tradicional para controlar a maioria dessas pragas é a aplicação de inseticidas químicos. A crescente preocupação sobre os efeitos negativos desses produtos vem encorajando o desenvolvimento de alternativas. Agentes do controle biológico aplicados de forma inundativa ou inoculativa têm sido pesquisados como método de controle alternativo para uma variedade de pragas em grande número de culturas, incluindo fruteiras tropicais. A maioria das pesquisas e aplicações em fruteiras tropicais tem sido feita em citros, insetos. Em banana, o controle do moleque-da-bananeira, Cosmopolites sordidus Germar (Coleoptera: Curculionidae) com nematóides e fungus também é considerado de sucesso. Oryctes rhinoceros (L.) (Coleoptera: Scarabaeidae) é uma das principais pragas em côco e um dos mais importantes exemplos de controle biológico clássico por vírus não-ocluso. As pragas-chave em manga que têm sido controladas com diferentes agentes de controle microbiano são as moscas-das-frutas (Diptera: Tephritidae), com nematóides e fungos, o gorgulho-da-manga, Sternochetus mangiferae (Fabricius) (Coleoptera: Curculionidae), com fungos, e vários hemípteros com fungo. O controle microbiano de a maior aplicabilidade dessas tecnologias é o desenvolvimento de combinações compatíveis entre entomopatógenos, predadores e parasitóides juntamente com outras técnicas de controle. PALAVRAS-CHAVE: Bactéria, vírus, fungo, nematóideABSTRACT -A multitude of insects and mites attack fruit crops throughout the tropics. The traditional method for controlling most of these pests is the application of chemical pesticides. Growing concern on the negative environmental effects has encouraged the development of alternatives. Inundatively and inoculatively applied microbial control agents (virus, bacteria, fungi, and entomopathogenic nematodes) have been developed as alternative control methods of a wide variety of arthropods including tropical fruit pests. The majority of the research and applications in tropical fruit agroecosystems has been conducted in citrus, banana, coconut, and mango. Successful microbial control initiatives of citrus pests and mites have been reported. Microbial control of arthropod pests of banana includes banana weevil, Cosmopolites sordidus Germar (Coleoptera: Curculionidae) (with EPNs and fungi) among others Oryctes rhinoceros (L.) is one of the most important pests of coconut and one of the most successful uses of non-occluded virus for classical biological control. Key pests of mango that have fungi), and other pests. Also successful is the microbial control of arthropod pests of guava, papaya and pineapple. The challenge towards a broader application of entomopathogens is the development of successful combinations of entomopathogens, predators, and parasitoids along with other interventions to produce effective and sustainable pest management.

“…Mass-produced EPNs have been used for control of D. abbreviatus by citrus growers for over 20 years (Duncan et al 1999). Mass release of EPNs can effectively reduce larval populations of D. abbreviatus (Downing et al 1991;Schroeder 1992;Bullock et al 1999). However, the reported efficacy of EPNs against D. abbreviatus ranges from 0% to >90% suppression (Adair 1994;Bullock et al 1999;McCoy et al 2000), and thus improved consistency of this tactic is desired.…”

Subterranean Herbivore-induced Volatiles Released by Citrus Roots upon Feeding by Diaprepes abbreviatus Recruit Entomopathogenic Nematodes

Herbivore-induced volatile emissions benefit plant hosts by recruiting natural enemies of herbivorous insects. Such tritrophic interactions have been examined thoroughly in the above-ground terrestrial environment. Recently, similar signals have also been described in the subterranean environment, which may be of equal importance for indirect plant defense. The larvae of the root weevil, Diaprepes abbreviates, are a serious pest of citrus. Infestations can be controlled by the use of entomopathogenic nematodes, yet the interactions between the plant, insect and nematode are poorly understood and remain unpredictable. In bioassays that used a root zone six-arm olfactometer, citrus roots ('Swingle citrumelo' rootstock) recruited significantly more entomopathogenic nematodes (Steinernema diaprepesi) when infested with root weevil larvae than non-infested roots. Infested plants were more attractive to nematodes than larvae alone. Roots damaged by weevil larvae attracted more nematodes than mechanically damaged roots and sand controls. By dynamic in situ collection and GC-MS analysis of volatiles from soil, we determined that four major terpene compounds were produced by infested plant roots that were not found in samples from non-infested roots or soil that contained only larvae. Solvent extracts of weevil-infested roots attracted more nematodes than extracts of non-infested roots in a two choice sand-column bioassay. These findings suggest that Swingle citrus roots release induced volatiles as an indirect defense in response to herbivore feeding, and that some of these induced volatiles function as attractants for entomopathogenic nematodes.
