Cypermethrin caused 12% mortality in S. carpocapsae in a study by Negrisoli Jr et al (2010), whereas in our study mortality of S. carpocapsae caused by cypermethrin remained below 1%. Emamectin is fermented from Streptomyces avermitilis and is generally formulated as emamectin benzoate (Waddy et al 2007).…”

Combining environmentally friendly insecticides with entomopathogenic nematodes may constitute an effective alternative to conventional chemical control of many insect pests. The objective of this laboratory study was to evaluate the effects of selected insecticides which are commonly used for pest control in vegetables in China on osmotically treated and untreated infective juveniles of Steinernema carpocapsae strain All. The insecticides azadirachtin, chlorpyrifos, cypermethrin, fipronil, imidacloprid, malathion, thiamethoxam and chlorantraniliprole-thiamethoxam had no adverse effects on nematode survival and infectivity. In contrast, bisultap, emamectin benzoate, phoxim and rotenone proved harmful to S. carpocapsae All mainly by reducing infectivity of the infective juveniles to larvae of the greater wax moth, Galleria mellonella. Osmotic induction is a promising way to induce entomopathogenic nematodes into partial anhydrobiosis and thus increase environmental stress tolerance of the nematodes as well as their shelf life after production. The present results showed that osmotic treatment did not adversely affect fitness of the nematode in terms of its susceptibility to insecticides and even increased its tolerance to chlorpyrifos and rotenone. The results of this laboratory study indicate that several of the tested insecticides can be safely combined with S. carpocapsae All within an integrated pest management approach.

“…In our study, however, viability of S. carpocapsae IJ was not affected by emamectin benzoate, but their infectivity was impaired. Different findings among studies may be related to differences in formulation of the test compounds and in the experimental design (Koppenhöfer & Grewal 2005, Negrisoli Jr et al 2010.…”

“…However, Negrisoli Jr et al (2010) observed 88% survival in S. carpocapsae when exposed to Cypermethrin. Negrisoli Jr. et al (2008) reported that, pyrethroids registered higher mortality of S. carpocapsae (28.4%) compared to H. bacteriophora (5.6%) when exposed to Decis, similarly in our studies, H. indica showed higher survival as compared to S. carpocapsae.…”

“…In our study, however, viability of S. carpocapsae and H. indica was not affected by Proclaim ® (Emamectin benzoate), but their infectivity was zero in both the species of EPNs. Therefore, generalisations on EPNs tolerance to insecticides were inaccurate, because different findings among studies may be related to differences in chemical composition and formulation of the product (Koppenhofer and Grewal, 2005;Negrisoli Jr et al, 2010). Therefore, studies of the interac- tion and compatibility between insecticides and EPNs are recommended before field applications in IPM programs.…”

ABSTRACT:The gram pod borer, Helicoverpa armigera (Lepidoptera: Noctuidae) is considered as a key pest of pigeonpea and is also a major polyphagous pest of several agricultural and horticultural crops in India. Combining chemical insecticides with Entomopathogenic Nematodes (EPNs) could be an effective alternative to reduce the use of harmful chemicals. Experiments were conducted to determine the compatibility of Steinernema carpocapsae and Heterorhabditis indica with registered insecticides used for H. armigera control in pigeon pea, under laboratory conditions. Compatibility of the insecticides with EPNs was evaluated by observing infective juveniles (IJs) survival and virulence of Galleria mellonella at 24 and 48 h after dipping in insecticide solutions. It was observed that, insecticides showed moderate effect on IJs survival. IJs were able to infect G. mellonella larvae after exposure to these chemicals, but their progeny production was significantly (P < 0.05) reduced. Both nematode species showed differential sensitivity to the tested insecticides, with H. indica exhibiting better tolerance than S. carpocapsae. The studies revealed that the chemicals showed a strong sub lethal effect on the nematode reproductive potential, limiting seriously their possible recycling in the field.

“…Studies have also been conducted to assess the potential of these nematodes against leaf pests. In a field experiment with leaf application of different strains, with or without addition of adjuvants, Negrisoli et al [93] observed that H. bacteriophora RS107 + adjuvant (sorbitol) was the most effective treatment against Bonagota salubricola (Meyrick) (Lepidoptera: Tortricidae), an important apple tree pest. Bellini & Dolinski [26] also reported the potential of leaf application of EPNs to control the sugarcane borer, Diatraea saccharalis (Fabricius) (Lepidoptera: Crambidae).…”

HIGHLIGHTS• Lauro Travassos in 1927 created genus Steinernema.• Two new species of entomopathogenic nematodes were described.• Studies on ecology, biology, production, formulation and application of native species have been carried out since 2000. ABSTRACT:In Brazil, the first study with entomopathogenic nematodes (EPNs) was conducted by Lauro Travassos in 1927, when he created the genus Steineria, that latter was changed to Steinernema. After important meetings and courses, there was a great development of EPNs research in various states by different research groups in Brazil. Many EPN species were isolated throughout the country and two new species described: Heterorhabditis amazonensis and Steinernema brazilense. The behavioral aspects, life cycle and pathogenicity of native EPNs were analyzed. Also their persistence and survival in the soil and the biotic and abiotic factors that may affect their efficiency as biocontrol agents. Due to the particular native species characteristics, production, formulation and application technologies were developed for them. Here in we summarize main Brazilians studies in different areas using EPNs. This is the first review on the subject in Brazil.Keywords: biology, ecology, behavior, production, formulation.Cite as Dolinski C, Monteiro C, Andaló V, Leite LG.
