“…We observed that chlorantraniliprole at low-lethal concentrations could also prolong A. ipsilon larval development (fifth and sixth stages). Previous studies have demonstrated that low doses of chlorantraniliprole could prolong the development time of many lepidopteran insect pests 10,34–36 . These results are consistent with those observed with the anthranilic diamide insecticide cyantraniliprole, which also prolonged the larval development of some lepidopteran pests 29,37 .…”

Agrotis ipsilon (Lepidoptera: Noctuidae) is a major underground pest that damages many agricultural crops in China and other countries. A diet-incorporation-based bioassay was conducted to evaluate the sublethal effects of the novel anthranilic diamide chlorantraniliprole on the nutritional physiology, enzymatic properties and population parameters of this cutworm. Chlorantraniliprole exhibited signs of active toxicity against third instar larvae of A . ipsilon , and the LC 50 was 0.187 μg.g −1 of artificial diet after treatment for 72 h. The development time of the larval, pupal and adult stages was significantly affected after chlorantraniliprole exposure, compared to the control treatment. Relative to the control treatment, chlorantraniliprole decreased pupal and adult emergence rates, fecundity and fertility and increased the proportions of developmental deformities, the adult preoviposition period (APOP) and the total preoviposition period (TPOP). Furthermore, compared to those treated with the control, A . ipsilon larvae treated with low doses of chlorantraniliprole decreased food utilization and nutrient content (protein, lipid, carbohydrate, trehalose), showed lower pupal weights and growth rates. Compared with the control treatment, chlorantraniliprole significantly reduced digestive enzyme activities and observably increased detoxifying and protective enzyme activities and hormone titers. Importantly, these chlorantraniliprole-induced changes affected life table parameters of the cutworm. These results suggest that chlorantraniliprole at low concentrations can impair A . ipsilon development duration, normal food consumption and digestion process, enzymatic properties, hormone levels, fecundity and population levels. Chlorantraniliprole exhibit the potential to be exploited as a control strategy for this cutworm.

“…Chlorantraniliprole has also been shown to prolong the development times of some lepidopteran insect pests, including; Plutella xylostella, S. littoralis, and Spodoptera cosmioides [65,66,67]. In this study, both insecticides and their nano-forms did not show any significant differences in other biological parameters, including pupal weight, pupation%, and emergence%, except for the LC 50 of nano-thiocyclam, which exhibits a significant difference in pupation% and emergence%.…”

High-frequency doses of chemical pesticides cause environmental pollution with high pesticide residues. In addition, increasing insecticide resistance in many insect pests requires novel pest control methods. Nanotechnology could be a promising field of modern agriculture, and is receiving considerable attention in the development of novel nano-agrochemicals, such as nanoinsectticides and nanofertilizers. This study assessed the effects of the lethal and sublethal concentrations of chlorantraniliprole, thiocyclam, and their nano-forms on the development, reproductive activity, oxidative stress enzyme activity, and DNA changes at the molecular level of the polyphagous species of black cutworm Agrotis ipsilon. The results revealed that A. ipsilon larvae were more susceptible to the nano-formsthan the regular forms of both nano chlorine and sulfur within the chlorantraniliprole and thiocyclam insecticides, respectively, with higher toxicities than the regular forms (ca. 3.86, and ca.2.06-fold, respectively). Significant differences in biological parameters, including developmental time and reproductive activity (fecundity and hatchability percent) were also observed. Correspondingly, increases in oxidative stress enzyme activities were observed, as were mutagenic effects on the genomic DNA of A. ipsilon after application of the LC50 of the nano-forms of both insecticides compared to the control. The positive results obtained here have led us to apply these nano-forms indifferent insect models in additional studies.

“…The LC 30 and LC 50 of the benzothiazole treatments significantly shortened the larval duration of T. castaneum , which differs from the most common response of insects to insecticides. Generally, two regulation modes of development are adopted by insects in response to insecticide stress, and a prolonged development time is the most frequently reported sublethal effect of insecticides on development . For example, Salpichroa origanifolia and flufenoxuron delay the development time of T. castaneum .…”

“…Under practical conditions, not only lethal but also sublethal effects exist among all insecticides. Insecticides may be photolyzed or hydrolyzed, and insects can move away from concentrated‐insecticide exposure areas, therefore insects live in an environment with sublethal concentrations of insecticides for a longer time than they live under conditions with lethal concentrations . Thus, a comprehensive evaluation of a new insecticide should include both direct toxic effects and sublethal effects.…”

BACKGROUNDThe red flour beetle, Tribolium castaneum Herbst (Coleoptera: Tenebrionidae), is an important stored‐product pest that is distributed worldwide and has developed resistance to many insecticides. Identifying novel and effective alternative insecticides is important for the control of T. castaneum. The volatile compound benzothiazole has been identified as having great acute toxic activity against T. castaneum. However, a comprehensive evaluation of a new insecticide should include both direct toxic effects and sublethal effects. The aim of this study was therefore to evaluate the effects of benzothiazole on the development and reproduction of T. castaneum.RESULTSExposure of fourth‐instar larvae to lethal and sublethal concentrations of benzothiazole (LC10, LC30 and LC50) significantly decreased pupation rates, food intake and growth rates in T. castaneum. Larval duration was significantly reduced by approximately 1 day in the LC30 and LC50 treatment groups. The LC50 benzothiazole caused a significant decrease in the weight of pupae and adults, fecundity and egg hatchability. Increased and decreased nutrient (carbohydrate and lipid) contents were observed in surviving larvae and pupae, respectively. The LC30 and LC50 treatments caused the down‐regulation of five growth‐positive regulated genes (PI3K, AKT, CyclinE, S6K1 and S6K2) and the up‐regulation of two growth‐negative regulated genes (4EBP and FOXO).CONCLUSIONBenzothiazole presented adverse effects on the development and reproduction of T. castaneum, further supporting benzothiazole as a highly active compound in stored‐product protection. © 2020 Society of Chemical Industry
