“…Reduced predation efficacy and mobility of larva, and high acute toxicity could be mentioned as examples of these effects (Provost et al 2003(Provost et al , 2005Rodrigues 2012;Ruberson et al 2007;Torres & Ruberson 2005). The high susceptibility of H. axyridis to lambda-cyhalothrin found here is comparable to other pyrethroid insecticides, such as fenpropathrin, esfenvalerate, bifenthrin at field rates under laboratory conditions (Cho et al 1997;Galvan et al 2005Galvan et al , 2006Michaud 2002;Michaud & Grant 2003). Overall, conventional insecticides (carbamate, organophoshate and pyrethroid) are considered lethal for younger stages and adults of H. axyridis, but some new products could have reduced toxicity depending on the life stage, for example, spinosad and indoxacarb (Galvan et al 2005;Youn et al 2003).…”

Dietary effects upon biological performance and lambda-cyhalothrin susceptibility in the multicolored Asian lady beetle, Harmonia axyridis

Considered a generalist species among the coccinellids, the multicolored Asian lady beetle Harmonia axyridis (Pallas) (Coleoptera: Coccinellidae) feeds upon small arthropods and non-prey plant products, a practice which might enhance its ability to colonize various ecosystems but carries the potential to expose it to prey quality variation and insecticide use. Thus, we examined the effect of four different diets on the development, reproduction, and response to the insecticide lambda-cyhalothrin in this species. Three groups of larvae received laboratory-reared diets: (i) eggs of Anagasta kuehniella (Zeller) (Ak); (ii) eggs of Sitotroga cerealella (Olivier) (Sc); and (iii) eggs of A. kuehniella + S. cerealella at the proportion 1:1; and one group received wild-caught cotton aphids, Aphis gossypii Glover (Ag). Notwithstanding the generalist feeding behavior of H. axyridis, development and reproduction results were superior with diets of Ag or Ak compared with the diet combining 1:1 Ak + Sc or the diet of Sc eggs only. Furthermore, the Sc diet did not result in satisfactory development and reproduction. Despite this significant variation in biological responses, insecticide susceptibility studies using adults that had been reared on these diets showed no statistically significant differences in susceptibility to the lambda-cyhalothrin.

“…In addition, these insecticides are very toxic to Coccinellid predators,16–21 limiting their usefulness in situations where vedalia beetle Rodolia cardinalis (Mulsant) (Coleoptera: Coccinellidae) is needed for control of cottony cushion scale Icerya purchasi Maskell (Hemiptera: Margarodidae). Pyrethroids and neonicotinoids caused more rapid mortality of M. gulosa , but these insecticide classes are toxic to most natural enemies needed for other pests of citrus 15, 20, 22–26. Finally, spinosad and abamectin were quite effective against M. gulosa in this study and are known to be fairly selective, favoring natural enemies 12, 20, 22, 25.…”

BACKGROUND: Egg and larval stages of citrus peelminer Marmara gulosa Guillén and Davis infesting zucchini squash Cucurbita pepo L. var ‘Revenue’ were exposed in the laboratory to a wide range of insecticide classes used in California citrus (organophosphate, carbamate, pyrethroid, neonicotinoid, insect growth regulator, fermentation products and sulfur) to determine peelminer response with and without a non‐ionic adjuvant or oil. RESULTS: All of the insecticides tested except sulfur reduced egg hatch and mine initiation. When the larval stage was treated, only buprofezin failed to reduce larval and pupal development. Cyfluthrin and spinosad, with the addition of adjuvant or oil, and abamectin combined with oil allowed no survivors at 7 days after treatment (DAT). The slower‐acting insect growth regulators pyriproxyfen and diflubenzuron applied in combination with adjuvant or oil allowed no survival of peelminer 21 DAT. A field trial showed 62.6–68.5% reduction in mined citrus fruit after two applications of diflubenzuron and no significant improvement of control with the addition of cyfluthrin. CONCLUSION: Bioassays indicate that M. gulosa is relatively susceptible to a wide range of insecticide classes in the laboratory. Lack of efficacy experienced in field trials would then be due to characteristics of the fruit or canopy that limit coverage, rather than to the effectiveness of the insecticides.

“…Similar effects could be expected from many relatively broad-spectrum insecticides. Michaud and Grant (2003) found that the toxicity to coccinellids was generally highest for carbamates (with the exception of methomyl), followed by pyrethroids, including fenpropathrin and organophosphates. Survival induce of Coccinellid species on fenpropathrin treatment at field recommended rate was very low (lower than 1%).…”

Toxicological effects of selected insecticides, fenpropathrin+pyriproxifen, acetamiprid, diafenthiuron, pyriproxifen, and chlorfenapyr were tested by direct spray and dry film methods in the laboratory against adult and larvae (L3-L4) of Delphastus catalinae (Horn) (Col., Coccinellidae), a predator of whiteflies, including cotton whitefly, Bemisia tabaci (Genn.). Water was used as untreated control. Fenpropathrin+pyriproxifen, acetamiprid, and diafenthiuron were harmful to larvae and adults of D. catalinae in both methods. Pyriproxifen was to be seemed harmless to adults in direct spraying technique; however it was harmful to the adults in dry film method. Eggs laid by a few adults which developed pyriproxifen treated larvae failure to hatch in dry film method. In conclusion, chlorfenapyr was innocuous to larvae and adults of D. catalinae in both methods. Fenpropathrin+pyriproxifen, acetamiprid, diafenthiuron and pyriproxifen would be incompatible with biological control of whitefly by D. catalinae.
