“…However, in Chloridea virescens (= Heliothis virescensa ) (Fabricius), a similar binding site was observed, with correlated structure and activities for anthranilic and phthalic acid diamides, indicating a common binding site for the two diamides . This similarity may be related to cross‐resistance to diamide insecticides, which has been reported for lepidopterans such as T. absoluta , P. xylostella , Spodoptera litura (Fabricius) and Chilo suppressalis (Walker) in China . Cross‐resistance can limit the useful period of an insecticide, and the occurrence of cross‐resistance between diamides can compromise the use of this group of insecticides to control S. frugiperda .…”

BACKGROUND Understanding the genetic basis of insect resistance to insecticides can help to implement insecticide resistance management (IRM) strategies. In this study, we selected a strain of Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae) resistant to chlorantraniliprole using the F2 screen method, characterized the inheritance of resistance and evaluated patterns of cross‐resistance to other diamide insecticides. RESULTS The chlorantraniliprole‐resistant strain (Chlorant‐R) was selected from a field‐collected population with an estimated allele frequency of 0.1316. The estimated median lethal concentration (LC50) values were 0.011 and 2.610 µg a.i. cm–2 for the susceptible (Sus) and Chlorant‐R strains, respectively, resulting in a resistance ratio (RR) of 237‐fold. The LC50 values of the reciprocal crosses were 0.155 and 0.164 µg a.i. cm–2, indicating that resistance is autosomally inherited. Resistance was characterized as incompletely recessive and monogenic at concentrations close to the recommended field rates of chlorantraniliprole. Survival of the resistant strain and heterozygous larvae in maize plants treated at the field rate was ∼ 60 (similar to the susceptible strain on untreated maize) and 15%, respectively. The Chlorant‐R strain showed low cross‐resistance to cyantraniliprole (RR ∼ 27‐fold) and very high cross‐resistance to flubendiamide (RR > 42 000‐fold). CONCLUSIONS The frequency of chlorantraniliprole resistance allele was moderately high in a field‐collected population of S. frugiperda. The inheritance of chlorantraniliprole resistance was characterized as autosomal, incompletely recessive and monogenic. S. frugiperda showed cross‐resistance to other diamide insecticides. These results provide essential information for the implementation of IRM programs to preserve the useful life of diamide insecticides for controlling S. frugiperda in Brazil. © 2019 Society of Chemical Industry

“…Chlorantraniliprole was introduced in China in 2008, leading to potential cross-resistance in Spodoptera litura [37] and low resistance in C. suppressalis in 2013 [38]. Isolation and detailed analysis of the full-length CsRyR cDNA were critical steps in understanding the molecular mechanism(s) that underlie the species selective toxicity of diamide insecticides, and minimizing or avoiding the risk of high resistance of C. suppressalis.…”

“…In vivo propagation is still the most promising method for the mass production of baculoviruses, because it is reliable and effective. The polyphagous and multivoltine characteristics of S. litura made it a recalcitrant agricultural pest resistant to multiple classes of synthetic insecticides (Shad et al, 2010;Ahmad & Mehmood, 2015;Sang et al, 2016). After inoculation, the moribund/dead insects are harvested for virus extraction.…”

Efficient production is essential for developing baculoviruses into marketable bioinsecticides. In this study, we evaluated how juvenile hormone (JH) III and the JH analog pyriproxyfen affected the production efficiency of Spodoptera litura (Fabricius) (Lepidoptera: Noctuidae) Nucleopolyhedrovirus (SpltNPV) in SpltNPV-inoculated early sixth instars. Both the JH III and pyriproxyfen treatments significantly enhanced the body size and weight of S. litura, which resulted in a 1.5-to 2-fold increase in the production of occlusion bodies (OBs). The OBs obtained from JH-and pyriproxyfen-treated larvae were as pathogenic as those produced in untreated larvae. More importantly, JH-or pyriproxy-fen-treated larvae consumed less than twice the amount of food consumed by two untreated larvae. These results indicate that JH and pyriproxyfen treatments improve the production efficiency of SpltNPV in S. litura. SpltNPV infection affected the development of S. litura not only as larvae, but also during subsequent growth stages and generations.
