“…39 -42 The phenomenon whereby different species of insects exhibit adverse effects on the same behaviours/physiological factors when treated with the same kind of insecticide is not rare. 38,39,42,43 This might be due to the different physiological reactions of different insect species, and a Different letters in the same column represent significant statistical differences (P < 0.05). Females only, males only and males and females denote that only females of the mating pairs, only males of the mating pairs and both males and females of the mating pairs in those groups were fed cyantraniliprole or untreated diet (control).…”

“…the different concentrations used, as well as the different developmental stages of the insect that are exposed. 39,43 Cyantraniliprole affected the mating competitiveness of both the treated females and the treated males. The higher dose significantly reduced mating competitiveness of the treated males compared with the control males, while the lower dose sharply increased the mating competitiveness of the treated males.…”

“…Appearance of supernumerary instars (6th-instar) larvae caused by insecticide could be another reason for prolonged larval duration (Moreau and Bauce 2003). There were many reports on pupal weight reduction of insects after exposed to sublethal insecticides (Stapel et al 1998;Seth et al 2004;Pineda et al 2007;Liu et al 2008;Rodríguez Enríquez et al 2010). Interestingly, in chlorantraniliprole exposed groups, the pupal weight was increased compared with control group, especially in LC 30 group.…”

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.

“…The diacylhydrazine insecticide family shows efficacy against lepidopteran larvae in the field and laboratory [6]. Tebufenozide and its methoxylated derivative methoxyfenozide present intrepid activity as agonists or mimic the insect molting hormone 20-hydroxyecdynose by inducing premature, incomplete ecdysis, resulting in the death of the exposed insects [7][8][9][10][11]. Halofenozide and chromafenozide are novel members of the diacylhydrazine insecticides belonging to the class of non-steroidal ecdysone agonists that are developed as insecticides against Lepidoptera [12,13].…”

The crystal structure of m-methoxy-N′-(m-anisoyl)-N-phenylbenzohydrazide has been determined by means of single-crystal X-ray diffraction. The title compound crystallizes in the monoclinic space group P 21/c with unit cell parameters: a = 8.7338(1), b = 24.5602(3), c = 9.6929(1) Å, β = 113.186(2)°, V = 1911.23(4) Å3, Z = 4. The dihedral angles between the mean plane of the central benzene ring and two terminal aromatic rings are 72.44(4)° and 89.90(4)°, respectively. The two methoxyphenyl rings are orthogonal with a dihedral angle of 89.74(4)°. The crystal packing is stabilized by a combination of N–H…O intermolecular hydrogen bonding and weak intermolecular C–H…O interactions. The X-ray structure was compared with the optimized counterpart calculated by the B3LYP/6-311G basis set and the results showed that the optimized geometry can reproduce the crystal structure parameters well.
