“…nas três doses (2,4; 12 e 60 JI/cm 2 ) + tiametoxam (250 g p.c./ha), diferiram significativamente e superaram a somatória das mortalidades obtidas com os nematóides e inseticidas das respectivas misturas, testados isoladamente nos respectivos ensaios, o que demonstra um efeito sinérgico decorrente dessas misturas, seguindo critério adotado por Benz (1971). Koppenhöfer et al (2002) avaliaram misturas de H. bacteriophora e S. glaseri com tiametoxam, no controle de larvas de Exomala orientalis (Waterhouse) (Coleoptera: Scarabaeidae), verificando efeitos também sinérgicos quando essas misturas foram comparadas aos nematóides e ao inseticida testados isoladamente. A associação de nematóides entomopatogênicos com o inseticida imidacloprido já vem sendo avaliada para o controle de larvas de escarabeídeos, proporcionando bons resultados de controle e, em muitos casos, apresentando efeitos sinérgicos na mortalidade dos insetos (Koppenhöfer & Kaya, 1998;Koppenhöfer et al, 2000;Koppenhöfer et al, 2003).…”

-The effect of combinations of the entomopathogenic nematodes Heterorhabditis indica Poinar, Karunakar & David, 1992 (strain IBCB-n5) and Steinernema sp. (strain IBCB-n6) at doses of 2.4;12 and 60 IJ/cm 2 , with sub-doses of the chemical insecticides fipronil, thiamethoxam and imidacloprid were tested in laboratory conditions against adults and larvae of the sugarcane billbug, Sphenophorus levis Vaurie, 1978. Firstly, the effect of fipronil (200 g A.I./ha), thiamethoxam (250 g A.I./ha) and imidacloprid (700 g A.I./ha) were evaluated on the nematode viability. The insecticides were compatible with the nematodes, not affecting the viability of the infective juvenile after 24 hours. For the experiments with adults, the treatments containing nematodes and insecticides tested separately showed mortality below 25%, except for the two highest doses of Steinernema sp. (at 12 and 60 IJ/cm 2 ), with mortality levels of 33.3% and 50% respectively. For the mixtures of the nematodes with sub-doses of thiamethoxam (62.5 g A.I./ha), the mortality levels increased significantly, reaching up to 66.7%, with the mixture of H. indica at 60 IJ/cm 2 , and 70% to 83.3% at all doses of Steinernema sp., showing synergistic effect at these combinations. The combination of H. indica and Steinernema sp. (12 IJ/cm 2 ) with thiamethoxam (62.5 g A.I./ha) against larva, the nematodes tested alone or in mixture with the insecticides showed mortality levels between 75% and 87.5%, indicating no advantage of the mixture for improving the insect mortality.KEYWORDS -integrated pest management, Heterorhabditis indica, Steinernema sp., sugarcane billbug, microbial control.

The banana weevil borer (Cosmopolites sordidus) is the main pest of banana crops, causing significant losses in productivity, being recommended control by chemical insecticides which cause several environmental impacts. On the other hand, entomopathogenic nematodes can be an alternative to the pest control, mainly because of their habits. Thus, this study aimed at evaluating isolated entomopathogenic nematodes under laboratory conditions and also their interaction with a chemical insecticide (carbofuran), aiming at their use for the weevil borer control. Sixteen Sterinernematidae and Heterorhabditidae isolates were evaluated, applied over the banana tree pseudo stem (100 JIs/cm 2 ) and they were compared to one another concerning mortality caused in adults individual of C. sordidus. The most infective isolates were subjected to in vivo multiplication at the host Galleria mellonella and interaction with the insecticide carbofuran, including in this case, viability and infectivity analysis of the entomopathogenic nematodes exposed to the product, as well as the effect of the insecticide on the symbiotic bacteria of the entomopathogenic nematodes. The experiments at this stage were conducted in completely randomized design and the data were subjected to ANOVA, with application of the Tukey test (p < 0.05). The most virulent isolates were IBCBn24 and IBCBn40 (respectively 33.3% and 36.7% of confirmed mortality), which also showed high multiplication in corpses. The insecticide did not affect the viability of the isolate, but it really harmed its infectivity, although it did not affect the development of the symbiotic bacterium.KEY WORDS: Heterorhabditis, Steinernema, biological control, chemical insecticide. RESUMONEMATOIDES ENTOMOPATOGÊNICOS E SUA INTERAÇÃO COM INSETICIDA QUÍMI-CO VISANDO AO CONTROLE DA BROCA-DA-BANANEIRA COSMOPOLITES SORDIDUS GERMAR (COLEOPTERA: CURCULIONIDAE). A broca-da-bananeira (Cosmopolites sordidus) é a principal praga dos cultivos de banana, acarretando perdas significativas na produtividade da cultura, sendo recomendados inseticidas químicos para seu controle, os quais causam impacto ambiental. Por outro lado, os nematoides entomopatogênicos podem ser uma alternativa para o controle da praga, principalmente devido aos seus hábitos. Assim, este trabalho teve como objetivo avaliar isolados de nematoides entomopatogênicos em condições de laboratório e a interação com inseticida químico (carbofurano), visando a sua utilização no controle da broca. Foram testados 16 isolados das famílias Sterinernematidae e Heterorhabditidae, aplicados sobre pseudocaule de banananeira (100 JIs/cm 2 ) e comparados entre si quanto à mortalidade causada em indivíduos adultos de C. sordidus. Os isolados mais infectivos foram submetidos a experimentos de multiplicação in vivo no hospedeiro Galleria mellonella e de interação com o inseticida carbofurano incluindo, neste caso, análise de viabilidade e infectividade dos nematoides expostos ao produto, bem como o efeito do inseticida sobre as bactérias simbionte...

“…EPNs are soil-dwelling parasites of insects, and they occur widely in natural and agricultural ecosystems across the world. They have been widely accepted as potential biocontrol agents of the larval stages of white grubs 3 . The genera Heterorhabditis (family: Heterorhabditidae Poinar 1976) and Steinernema (family: Steinernematidae Chitwood and Chitwood, 1937) have generated much interest as potential biocontrol agents as they carry the lethal symbiotic bacteria Photorhabdus and Xenorhabdus respectively, in their guts.…”
