“…The synthetic procedures for the title compounds are outlined in Scheme1 [23].The These results agree with [17] which described a series of substituted hydrazone derivatives possessing good activities against Spodoptera litura (Fabricius). [2] stated that chlorantraniliprole showed more toxic effect in feeding test of 2 nd and 4 th larval instars of cotton leaf worm under laboratory conditions.…”

“…Consequence, the continued application of traditional pesticides for controlling this pest can often lead to the development resistance, thus bringing about enormous losses in crop production. In recent years, several insecticidal phthalic diamides (fluobendiamide, chlorantraniliprole and cyantraniliprole), [2][3][4][5][6] which act on the ryanodine receptor, [7][8][9] were discovered and commercialized, however, their insecticidal spectrum is limited. Recently, a chlorantraniliprole skeleton was found to be very significant in the discovery of novel insecticides and several modifications around its structure have been industry [10,11].…”

Four 3,5-pyrazolidinedione derivatives namely, 4-(4`-chlorobenzylidene)-1-phenylpyrazolidine-3,5-dione (1), 4-(4`-nitrobenzylidene)-1-phenylpyrazolidine-3,5-dione (2), 2'-(4-chlorophenyl)-1phenyl-3,5-dioxo-1,2,3,5 tetrahydrospiropyrazole-4,3' oxirane (3) and 2'-(4-nitrophenyl)-1phenyl-3,5-dioxo-1,2,3,5 tetrahydrospiropyrazole-4,3' oxirane (4) were prepared in pure state and bioassayed against 2 nd and 4 th instars larvae of cotton leaf worm, Spodoptera littoralis (Boised) (Lepidoptera: Noctuidae) using feeding and dipping bioassay. The results of bioassays indicated that title compounds exhibit satisfactory insecticidal activities. Among those, compound (1) exhibit the highest insecticidal activities against 2 nd instar larvae, with LC 50s 3.23 and 0.619 mgL -1 for feeding, and 36.04 and 28.69 mgL -1 for dipping, after 48 and 72 h treatment. According to the toxicity index the compound (1) showed the highest larvicidal activity against 4 th instar larvae with LC 50s 141.33 and 76.12 mgL -1 for feeding larvae, and 26.94 and 12.29 mgL -1 for dipping larvae after 48 and 72 h treatment. These results showed that, the 2 nd larvae was more susceptible than 4 th instars larvae to these compounds. In addition, the insecticidal activity of these compounds was Aly A. Abd-Ella et al. 2 more effective on cotton leaf worm larvae in feeding bioassay as compared with the dipping treatment. The rest of the tested compounds possessed moderate to strong larvicidal activities against cotton leaf worm. In general, the results indicate the possible use of 3,5-pyrazolidinedione derivatives as components in integrated pest management program against S. littoralis.

“…The feeding inhibition (FI %) of the tested compounds was evaluated for 2nd and 4th larval instars of S. littoralis using leaf disc no choice bioassay method. FI% was calculated as follows: FI % = (C − T) / (C + T) × 100, where C: Consumption of control discs, T: Consumption of treated discs 39 . The antifeedant activity was assessed for cyromazine alone and its mixtures with the nanomaterials.…”

Excessive application of pesticides leads to contamination of the environment, which entails the necessity to seek solutions that employ substances which do not pose ecological hazards. So, the present study was conducted to explore the different effects of tungsten oxide (WRT), magnetic nanoparticles (MNPs), Cu-doped magnetic nanoparticles (MNP-Cu), the insecticide, cyromazine, and their binary mixtures against Spodoptera littoralis. The nanomaterials individually didn’t show any toxicity against S. littoralis stages. Cyromazine recorded the highest toxicity with LC50 values of 58.7, 45.6, and 70.5 mgL− 1 against eggs, 2nd, and 4th larvae, respectively. Nanoparticles showed an antagonistic effect which increased directly with concentrations. Cyromazine (100 mgL− 1) + MNP-Cu (500 mgL− 1) was the most repellent mixture for the 2nd and 4th larvae with feeding deterrence percent, 41.42% and 57.60%, respectively. Larval and pupal durations increased with increasing cyromazine and nanomaterial concentrations. Except for the cyromazine (25 mgL− 1) + WRT (500 mgL− 1) mixture, which recorded 27.3% adult emergence, no adult emergence was recorded by the 500 mgL− 1 nanomaterial mixtures. Some malformations were also recorded for S. littoralis stages after being treated with tested materials. Cyromazine/MNP-Cu mixtures gave the highest significantly increased in the enzyme activity of glutathione S-transferase and α-esterase compared to the control. Regarding the results obtained by the Q-PCR, the insect immune response for the treatments indicated a high immune response in all the treated insects compared to the control. In conclusion, the nanomaterial-cyromazine mixtures may be recommended as promising alternatives for S. littoralis control.

This work aims at throw light on the efficiency of Lufenuron (Owner 5%), diflubenzuron (Dimilin48%), Emamectin benzoate (Emafel4%) and Indoxacarb ( Strong 30%) on the 2 nd and 4 th larval instar of the cotton leaf warm, (Owner ) is the most potent insecticide against S. littoralis larvae ,which caused the shortest larval, pupal and adult durations being 11.26,10.80 and 6.33 days respectively. Current study was conducted on the insecticidal effect of Lufenuron on percentages of larval mortality (80%), pupation 20% and adult 53.7%. The tested dose level of all treatments showed highly histopathological disturbanecs in the midgut of this pest including distruction of the muscle layers, disorgarization in the epitheliul cells, separation of the peritrophic membrane as well as detachment of the basement membrane and appearance of vaculaizations . This observation might explain high mortality in treated larvae as compared to the control.
