“…Also in agreement with our findings, Hassan et al (1987) and Toda and Kashio (1997) reported a low toxicity of trichlorfon to larvae of C. carnea and Ferreira et al (2006) showed that Chrysoperla externa (Hagen) (Neuroptera: Chrysopidae) larvae were not affected by methoxyfenozide. However, in contrast with these results, deltamethrin (Bigler and Waldburger 1994) and phosmet (Sterk et al 1999) were slightly harmful and harmful, respectively to larvae, which might be explained by taking into account that higher concentrations of these MFRC = 14 mg A.I.…”

Effects of the maximum field recommended concentration of five pesticides currently used on peaches in Brazil; abamectin, deltamethrin, methoxyfenozide, phosmet and trichlorfon were tested on the predator Chrysoperla carnea (Stephens) (Neuroptera, Chrysopidae). Dimethoate was used as positive standard. Three analytical laboratory tests, based on IOBC-working group pesticides and beneficial organisms guidelines were used: (1) exposure to fresh pesticide residue on glass plates of (a) larvae (susceptible life stage) and (b) adults (less susceptible life stage); (2) direct spraying of eggs and pupae; (3) exposure of larvae and adults to pesticide residues on plant leaves at different intervals after application (persistence). In tests 1, abamectin was slightly harmful to C. carnea larvae and phosmet and trichlorfon were slightly harmful and moderately harmful to C. carnea adults, respectively. After direct spraying of eggs and pupae, all the pesticides were harmless. In the persistence tests, abamectin and trichlorfon were classified as short lived and therefore they could be considered for use in Integrated Pest Management (IPM) programs under special conditions (i.e. reduced direct contact). Phosmet, however, caused between 56.3 and 75.0% mortality up to 30 days after treatment and it was rated as persistent. No sublethal effects were detected in the reproductive behaviour of adults (fecundity and fertility) compared with the control in any treatment. In conclusion, the insecticides with little or no toxicity to C. carnea such as abamectin, deltamethrin and methoxyfenozide could be considered as IPM-compatible, subject to further field studies.

“…That difference may be as related to physiological responses specific to the insects tested, inasmuch as it was not mentioned the species concerned. Lingren & Ridgway (1967), Hassan et al (1987) and Toda & Kashio (1997) also found that larvae of Chrysoperla carnea (Stephens, 1836) were not affected negatively by the trichlorfon. The insecticides fenpropathrin and chlorpirifos caused less than 30% of mortality of the larvae only at 25 days after its application, being regarded as moderately persistent (Table 3).…”

Residual action of insecticides to larvae of Chrysoperla externa (Hagen, 1861) (Neuroptera: Chrysopidae) under greenhouse conditions

et al. 2003

-This work was designed to evaluate the residual action of the insecticides trichlorfon, triflumuron, endosulfan, fenpropathrin, chlorpirifos, tebufenozide and esfenvalerate, sprayed on cotton plants, to second-instar larvae of Chrysoperla externa (Hagen, 1861), under greenhouse conditions. The experimental design was completely randomized with ten replicates. Three larvae were released on each plant, in the 1 st , 12 th and 23 rd day after pesticides spray. Tebufenozide and esfenvalerate were little persistent (class one), while trichlorfon, triflumuron and endosulfan were slightly persistent, decreasing the survival of C. externa larvae over 30%, up to 14 days after spray. Fenpropathrin and chlorpirifos caused mortality over 30%, up to 25 days after spray, being classified as fairly persistent.INDEX TERMS: Selectivity, predator, pesticides, cotton.

“…1 Classe de toxicidade segundo a IOBC (Hassan et al 1987 Hassan et al (1987), que classificaram o composto, quando utilizado na dose de 0,1 ml/L, como inócuo (classe 1), por causar baixa mortalidade às larvas de C. carnea, o que pode ser devido à maior capacidade dessa espécie de crisopídeo em metabolizar o inseticida, ou mesmo à sua habilidade de se desintoxicar quando exposta ao produto. Divergem também daqueles obtidos por Toda & Kashio (1997), no Japão, que observaram que o triclorfom não foi tóxico para larvas de C. carnea.…”

-The objective of this work was to evaluate the effect the insecticides endosulfan (1.05 g a.i./L), esfenvalerate (0.075 g a.i./L), fenpropathrin (0.09 g a.i./L), trichlorfon (0.09 g a.i./L) and triflumuron (0.0375 g a.i./L), used to control Alabama argillacea (Hübner), on eggs and larvae of Chrysoperla externa (Hagen), under greenhouse conditions. Egg viability, duration of the embryonic period and survival of first-instar larvae ecloded from treated eggs were evaluated. For first, second and third-instar larvae treated with the insecticides, subsequent survival of the larvae and pupae, as well as viability of the eggs produced by the emerged adults, were evaluated. The insecticides esfenvalerate and triflumuron caused a significant increase in the embryonic period of C. externa. Endosulfan, fenpropathrin, trichlorfon and triflumuron were highly toxic to larvae, with mortality rates ranging from 71% to 100%. Esfenvalerate caused only about 20% mortality of the first-and thirdinstar larvae and 38% of the second-instar larvae. Besides causing low larval mortality, esfenvalerate did not affect pupae survival or the reproductive capacity of the adults in the studied period, thus showing good potential for use in integrated pest management in cotton crops. Avaliou-se a viabilidade dos ovos, o período embrionário e a sobrevivência de larvas de primeiro ínstar eclodidas desses ovos. Larvas de primeiro, segundo e terceiro ínstares foram pulverizadas com os inseticidas, verificando-se a sobrevivência das pupas obtidas, e a viabilidade dos ovos produzidos pelos adultos emergidos. Esfenvalerate e triflumurom provocaram aumento do período embrionário de C. externa, sendo que nenhum dos inseticidas avaliados causou redução na viabilidade dos ovos. Endosulfam, fempropatrina, triclorfom e triflumurom foram altamente tóxicos à fase larval do predador, acarretando mortalidade de 71% a 100%. Esfenvalerate causou mortalidade média de 20% para larvas de primeiro e terceiro ínstares e de 38% para o segundo ínstar, não afetando a viabilidade das pupas obtidas e a capacidade reprodutiva dos adultos, apresentando possibilidades de recomendação para uso em programas de manejo integrado de pragas na cultura do algodoeiro. PALAVRAS-CHAVE: Crisopídeo, produto fitossanitário, controle biológico A cultura do algodoeiro possui importantes insetos-praga que causam danos consideráveis, destacando-se o curuquerê Alabama argillacea (Hübner). Em altas infestações, essa espécie pode causar prejuízos, desfolhando as plantas prematuramente e incapacitando-as de produzir sementes e fibras maduras. Muitas vezes o manejo desse inseto é realizado com uso de produtos de amplo espectro de ação que podem afetar os insetos benéficos presentes nessa cultura (Gridi-Papp et al. 1992).Os crisopídeos têm despertado interesse dos pesquisadores por serem eficientes predadores de ampla diversidade de presas, tais como pulgões, moscas-brancas, cochonilhas, lagartas, ácaros etc., podendo ser úteis em programas de manejo integrado de pragas para várias cultur...
