“…Indoxacarb resistance increased in Shandong, with moderate levels of resistance found in four populations and high resistance 20,21) It has been found to be effective against pests of the orders Lepidoptera, Diptera, Thysanoptera, and some species of Coleoptera and Orthoptera. 22,23) In our study, eight out of 10 populations of S. exigua exhibited moderate to high resistance to spinosad, while only two populations showed low resistance levels. Although spinosad has a novel action mechanism and no cross-resistance to many different insecticides, many pest species have still generated different levels of resistance.…”

The spinosyns are a large family of unprecedented compounds produced from fermentation of two species of Saccharopolyspora. Their core structure is a polyketide-derived tetracyclic macrolide appended with two saccharides. They show potent insecticidal activities against many commercially significant species that cause extensive damage to crops and other plants. They also show activity against important external parasites of livestock, companion animals and humans. Spinosad is a defined combination of the two principal fermentation factors, spinosyns A and D. Structure-activity relationships (SARs) have been extensively studied, leading to development of a semisynthetic second-generation derivative, spinetoram. The spinosyns have a unique mechanism of action (MOA) involving disruption of nicotinic acetylcholine receptors. When compared with many other insecticides, the spinosyns generally show greater selectivity toward target insects and lesser activity against many beneficial predators as well as mammals and other aquatic and avian animals. Their insecticidal spectrum, unique MOA and lower environmental effect make them useful new agents for modern integrated pest management programs. As a result, this work has received U S Presidential Green Chemistry Challenge Awards.

“…Frequent application of insecticides had lead to resistance development of beet armyworm to conventional insecticides, and failure of chemical control was reported for this insect pest (Aldosari et al 1996;Moulton et al 2000Moulton et al , 2002Liu et al 2002a, b;Osoria et al 2008). In this scenario, new insecticides with unique mode of action are required as an alternative in integrated management program of beet armyworm.…”

The lethal and sublethal effects of chlorantraniliprole against Spodoptera exigua (Hübner) were evaluated under laboratory conditions by oral exposure of neonate larvae to the compound. The 72 h LC 50 value of this insecticide to S. exigua was found to be 12.747 lg l -1 . A progressive larval mortality of 24.32% for LC 30 treatment and 42.61% for LC 50 treatment was observed from 4th to 6th day after exposure, which resulted in the reduced pupation rates in exposure groups. The sublethal effects of this chemical were indicated by prolongation of larval period, the increase of pupal weight and decrease in hatch rate of egg. Chlorantraniliprole at LC 30 and LC 50 rate significantly delayed larval development; the developmental duration of surviving larvae was extended for 22.5 and 28.6%, respectively, compared with that of control group. LC 30 treatment increased the mean weight of pupa and induced to the production of heavier pupa ([150 mg). In LC 50 treatment, heavier pupa also showed up but the mean weight of pupa was not influenced. The egg hatch rate in LC 50 group was significant lower than that in control and LC 30 groups. No significant differences in pupal duration, emergence rate, sex ratio, egg number per female, and longevity of adults were observed among treatments. Chlorantraniliprole had exceptional activity against S. exigua according to concentration-response bioassay in laboratory, and the toxicities were primarily resulted from immediate lethality.
