“…In a previous study, H. axyridis Þrst instars were also the most susceptible and pupae were the most tolerant to the insecticides acetamiprid, etofenprox, imidacloprid, and thiamethoxam (Youn et al 2003). Differences in susceptibility among life stages may occur because of changes in enzyme activity and target-site sensitivity (Cho et al 2002).…”

Use of insecticides with low toxicity to natural enemies is an important component of conservation biological control. In this study, we evaluated the toxicity of insecticides used in sweet corn, Zea mays L., and soybean, Glycine max (L.) Merr., to the multicolored Asian lady beetle, Harmonia axyridis (Pallas), under laboratory and field conditions. Field experiments conducted in sweet corn in 2003 and 2004 and in soybean in 2003, showed that H. axyridis was the most abundant predator. In sweet corn, densities of H. axyridis larvae in plots treated with spinosad or indoxacarb were generally higher than in plots treated with chlorpyrifos, carbaryl, bifenthrin, and A-cyhalothrin. In soybean, densities of H. axyridis larvae in plots treated with chlorpyrifos were higher than in plots treated with lambda-cyhalothrin. Laboratory experiments were conducted to evaluate the acute toxicity of insecticides to eggs, first and third instars, pupae, and adults. Spinosad, followed by indoxacarb, were the least toxic insecticides for all life stages of H. axyridis. Conventional insecticides showed high toxicity to H. axyridis when applied at field rates under laboratory conditions. Overall, first instars were most susceptible to the insecticides tested, followed by third instars and adults, eggs, and pupae. Our results suggest that spinosad, and to a lesser extent indoxacarb, offer reduced toxicity to H. axyridis and would be beneficial for conservation biological control in agricultural systems where H. axyridis is abundant.

“…The effects observed on C. rufilabris may have been due to this species being treated as first instar larvae. Several authors have shown increased susceptibility to pyrethrins of insects in early developmental stages (Cho et al, 2002;Kraiss and Cullen, 2008a). This increased susceptibility in early stages correlates with reduced ability to metabolize the insecticides (Cho et al, 2002).…”

This increased susceptibility in early stages correlates with reduced ability to metabolize the insecticides (Cho et al, 2002). The effects on C. rufilabris may have also been due to the mode of action of azadirachtin, which is a botanical insect growth regulator (Mordue & Blackwell, 1993).…”

The invasive soybean aphid, Aphis glycines Matsumura, is an important pest in North American soybean production. Predators can play an important role in suppressing A. glycines. However, current A. glycines management practices rely primarily on broad-spectrum insecticides, which can adversely affect predator populations. An alternative is the use of selective insecticides that control the targeted pest species, while having a reduced impact on natural enemies. In greenhouse and laboratory assays, we tested the effects of lambda-cyhalothrin, two rates of flonicamid, which is currently not registered for use in soybean, and a formulated mixture of A c c e p t e d M a n u s c r i p t Downloaded by [University of Nebraska, Lincoln] at 16:08 13 April 2015 azadirachtin and pyrethrins on A. glycines and its natural enemies, Chrysoperla rufilabris (Burmeister), Orius insidiosus (Say) and Hippodamia convergens (Guerin-Meneville). All insecticides significantly reduced A. glycines population growth. Lambda-cyhalothrin was highly toxic to the natural enemies tested. Flonicamid showed the lowest toxicity to natural enemies, but the high rate did decrease survival of O. insidiosus. The mixture of pyrethrins and azadirachtin was toxic to larvae of C. rufilabris and adult O. insidiosus. Moreover, the mixture of pyrethrins and azadirachtin increased the developmental time of C. rufilabris. These results indicate potential for flonicamid and the mixture of pyrethrins and azadirachtin to increase compatibility between chemical and biological controls.

“…Grafton and Gu (2003) demonstrated that synthetic pyrethroids had a significant negative impact on the predatory vedalia beetles larvae and adults. Cho et al, (2002) the susceptibility of different organisms is varied due to differences in target-site sensitivity as well as quality and quantity of enzyme activities of the individual organisms. Shima, (2013) Results showed that thiamethoxam didn't have any significant effects on the developmental time of third instars, adult longevity and fecundity.…”

The relative toxicity of Thiamethoxam, lambda-cyhalothrin, dimethoit, chlorpyrifos and (lambda-cyhalothrin + chlorpyrifos) were tested against the Cabbage aphid, Brevicoryne brassicae (L.) on Cauliflower in EL-Minia regon during 2015 season. The population of Cabbage aphid on Cauliflower plants was nearly the same in all the treat plants before application with insecticides in 2015 season. The population density of Cabbage aphid was strongly decreased in all treated plots after 3 days from insecticides application compared with control. The average reduction of all compounds during experiment were 86.8 and 76.1for Thiamethoxam and (Chlorpyriphos + lambda-cyhalothrin), respectively. Also, the results revealed that all compounds differed significantly in their toxicity except Lambda-cyhalothrin , Dimethoit and Chlorpyrifos (no significant difference between for their toxicity, which were 64.3, 66.5 and 62.3 percent reduction, respectively). In general, data showed that superiority of Thiamethoxam as systemic insecticides activities than nonsystemic insecticides in their toxicity after 3,7 and 15 days. On the other hand, the average reduction of all compounds during experiment to Coccinella undeciumpunctata L. were 45, 38.3, 38, 37.3 and 30.7, for (Chlorpyriphos + lambdacyhalothrin), Chlorpyriphos , Lambda-cyhalothrin, Dimethoit and Thiamethoxam, respectively. The degree of selectivity to all compounds was selectivity but Thiamethoxam was the highest. Also, Thiamethoxam was good selectivity on Scymuns spp. and all compounds were selectivity and the average reduction to all compounds during experiment to Scymuns spp were 41.7, 35, 31.4, 31 and 16 percent reduction for (Chlorpyriphos + lambda-cyhalothrin), Lambda-cyhalothrin, Dimethoit , Chlorpyriphos and Thiamethoxam, respectively. In general, data showed the tested compounds did not completely eliminate the beneficial arthropods. The superiority of Thiamethoxam as systemic insecticides activities than non-systemic.
