“…Columns bearing different letters differ significantly (oneway ANOVA followed by Turkey HSD) Forbes 2000). Within arthropod species, it has been clearly demonstrated that imidacloprid stimulates the reproduction of the two-spotted spider mite (James and Price 2002) and of the green peach aphid (Yu et al 2010). Furthermore, according to our results, Zanuncio et al (2003) found that sublethal doses of permethrin reduced the pre-oviposition duration of Supputius cincticeps (Stål) (Heteroptera: pentatomidae).…”

“…However, possible positive sublethal effects of pesticides have been also reported (Desneux et al 2007). For imidacloprid in particular, scientists have reported that sublethal concentrations can lead to increased fecundity and longevity whereas high concentrations decrease such biological traits (Cutler et al 2009;Yu et al 2010). Various effects of imidacloprid on insect behavior have also been reported (Ramirez-Romero et al 2005;Han et al 2010b;He et al 2012).…”

“…Various effects of imidacloprid on insect behavior have also been reported (Ramirez-Romero et al 2005;Han et al 2010b;He et al 2012). Studies have documented sublethal effects of imidacloprid on various agricultural pests (Zeng et al 2006;Wang et al 2008;Bao et al 2009;Bonia et al 2009;Cutler et al 2009;Yu et al 2010) but to date no information is available on potential sublethal effects of imidacloprid on mirid bugs. However, identifying and characterizing such effects could be crucial for understanding of the global effects of imidacloprid on mirid bugs and therefore for optimizing their management in crops.…”

Assessment of physiological sublethal effects of imidacloprid on the mirid bug Apolygus lucorum (Meyer-Dür)

Apolygus lucorum (Meyer-Dür) (Hemiptera: Miridae) is currently one of major mirid pests in the Yangtze River and the Yellow River regions in China. Imidacloprid (neonicotinoid) is widely used against pierce-sucking pest insects, including against A. lucorum. In addition to its direct lethal effect, multiple negative sublethal effects may also occur in exposed insects. We assessed potential sublethal effects of imidacloprid on some biological characteristics of A. lucorum with the aim of increasing rational use of imidacloprid against that cotton pest. The lethal toxicity of imidacloprid on adults of A. lucorum was determined in laboratory conditions by a topical application bioassay (LD(50) = 6.70 ng a.i. [active ingredient]/A. lucorum adult). We also estimated a sublethal dose, LD(5) (0.38 ng a.i./adult), a low lethal dose, LD(25) (1.96 ng a.i./adult), and moderate lethal dose, LD(40) (3.97 ng a.i./adult). The sublethal dose of imidacloprid (LD(5)) shortened the pre-oviposition period of females but increased the time required for eggs to develop (i.e. longer embryogenesis). The low lethal dose (LD(25)) also reduced the pre-oviposition period. Females exposed to the LD(40) laid eggs that developed faster but overall percentage of eggs hatching was reduced. LD(25) and LD(40) reduced longevity of males but not of females. In addition, the susceptibility to seven insecticides generally used on Chinese crops was not modified in A. lucorum previously exposed to the LD(25) of imidacloprid. Our results demonstrate sublethal effects of low doses of imidacloprid on A. lucorum (notably on pre-oviposition period and egg development) which may have an impact on population dynamics of this pest.

“…Stimulated reproduction of the green peach aphid (Myzus persicae) by exposure to sublethal doses of imidacloprid had been reported previously (Yu et al 2010). This hermetic effect undermines the effectiveness of the insecticide in controlling the target pest, and it seems to be accompanied by a complex pattern of up-and downregulation of genes during exposure.…”

New information on the lethal and sublethal effects of neonicotinoids and fipronil on organisms is presented in this review, complementing the previous Worldwide Integrated Assessment (WIA) in 2015. The high toxicity of these systemic insecticides to invertebrates has been confirmed and expanded to include more species and compounds. Most of the recent research has focused on bees and the sublethal and ecological impacts these insecticides have on pollinators. Toxic effects on other invertebrate taxa also covered predatory and parasitoid natural enemies and aquatic arthropods. Little new information has been gathered on soil organisms. The impact on marine and coastal ecosystems is still largely uncharted. The chronic lethality of neonicotinoids to insects and crustaceans, and the strengthened evidence that these chemicals also impair the immune system and reproduction, highlights the dangers of this particular insecticidal class (neonicotinoids and fipronil), with the potential to greatly decrease populations of arthropods in both terrestrial and aquatic environments. Sublethal effects on fish, reptiles, frogs, birds, and mammals are also reported, showing a better understanding of the mechanisms of toxicity of these insecticides in vertebrates and their deleterious impacts on growth, reproduction, and neurobehaviour of most of the species tested. This review concludes with a summary of impacts on the ecosystem services and functioning, particularly on pollination, soil biota, and aquatic invertebrate communities, thus reinforcing the previous WIA conclusions .

“…Approximately 560 million kg of insecticide were used globally in 2001, over three-quarters of which was for agricultural purposes (Kiely et al 2004). The Environmental Protection Agency has approved the use of about 225 insecticidal active ingredients, and there are typically multiple formulations of each used in a variety of applications (Yu 2008).…”

Insects, Insecticides and Hormesis: Evidence and Considerations for Study

Insects are ubiquitous, crucial components of almost all terrestrial and fresh water ecosystems. In agricultural settings they are subjected to, intentionally or unintentionally, an array of synthetic pesticides and other chemical stressors. These ecological underpinnings, the amenability of insects to laboratory and field experiments, and our strong knowledgebase in insecticide toxicology, make the insect-insecticide model an excellent one to study many questions surrounding hormesis. Moreover, there is practical importance for agriculture with evidence of pest population growth being accelerated by insecticide hormesis. Nevertheless, insects have been underutilized in studies of hormesis. Where hormesis hypotheses have been tested, results clearly demonstrate stimulatory effects on multiple taxa as measured through several biological endpoints, both at individual and population levels. However, many basic questions are outstanding given the myriad of chemicals, responses, and ecological interactions that are likely to occur.
