“…In addition, insecticide applications have negatively affected survival and fitness of natural enemies of Liriomyza (Trumble and Toscano 1983; Darvas and Polgar 1998; Weintraub 2001; Prijono et al 2004; Bjorksten and Robinson 2005; Hidrayani et al 2005; Kaspi and Parrella 2005; Tran et al 2005; Hossain and Poehling 2006). …”

Liriomyza leafminers (Diptera: Agromyzidae) are cosmopolitan, polyphagous pests of horticultural plants and many are resistant to insecticides. Producers in South Texas rely on insecticides as the primary management tool for leafminers, and several compounds are available. The objective of this study is to address the efficacy of these compounds for controlling Liriomyza while minimizing their effects against natural enemies. Research plots were established at Texas AgriLife research center at Weslaco, Texas in fall 2007 and spring 2008 seasons, and peppers were used as a model crop. Plots were sprayed with novaluron, abamectin, spinetoram, lambda-cyhalothrin and water as treatments according to leafminer infestation; insecticide efficacy was monitored by collecting leaves and infested foliage. Plant phenology was also monitored. Novaluron was the most effective insecticide and lambda-cyhalothrin showed resurgence in leafminer density in fall 2007 and no reduction in spring 2008. Other compounds varied in efficacy. Novaluron showed the least number of parasitoids per leafminer larva and the lowest parasitoid diversity index among treatments followed by spinetoram. Liriomyza trifolii (Burgess) was the sole leafminer species on peppers, and 19 parasitoid species were found associated with this leafminer. Application of these insecticides for management of leafminers with conservation of natural enemies is discussed.

“…However, the higher rates (500 and 1,000 mg active ingredient per liter) when applied to first instars did prolong overall development to adult whereas second and third instars and pupae were not affected [109]. This indicates that the specific life stage exposed to insect growth regulators may vary in susceptibility with early instars tending to be more susceptible than later instars and adults to chitin synthesis inhibiting insect growth regulators [108,[110][111]. In addition, the concentration in which natural enemies are exposed to may influence any indirect effects to these types of insect growth regulators.…”

“…Insect growth regulators (IGRs) as third-generation insecticides have a specific mode of action on insects and a lower toxicity against vertebrates than the conventional insecticides [1][2][3][4]. However, heavy applications of such pesticides in agricultural areas may also impact not only on the target species but also on nontarget organisms in and adjacent to the target areas.…”

“…IGRs have adverse effects on vertebrate and invertebrate organisms and are known to be acutely toxic to some organisms. The level of toxicity to invertebrates, however, does not seem to be similar to that of vertebrates and needs further investigation [2]. As it is difficult and expensive to detect the presence and exact concentrations of these insecticides in the environment, due to their relatively short half-lives, it may be more effective to use biomarkers to assess exposure.…”

Earthworms are particularly important soil macroinvertebrates and are often used in assessing the general impact of pesticide pollution in soil. The present study was conducted in order to investigate the toxicity of three insect growth regulators (IGRs) buprofezin, lufenuron, and triflumuron, at different application rates and exposure times toward mature earthworms Aporrectodea caliginosa. The effects of these pesticides on the growth rate in relation to the activities of acetylcholinesterase (AChE) and glutathione S-transferase (GST) as biochemical indicators were evaluated to elucidate the mechanisms of action. Toxicity studies indicated that lufenuron was the most harmful pesticide to mature earthworms, followed in descending order by buprofezin and triflumuron. A reduction in growth rate in all pesticide-treated worms was dose-dependent over the 28-day exposure period, which was accompanied by a decrease in AChE and GST activities. Relationships between growth rate, AChE, and GST provided strong evidence for the involvement of pesticidal contamination in the biochemical changes in earthworms, which can be used as a bioindicator of soil contamination by pesticides.
