The retardant effect of 2-Tridecanone, mediated by Cytochrome P450, on the Development of Cotton bollworm, Helicoverpa armigera

Table 1 Effect of 2-TD on larval development

Treatment group	Pupation time (d)	Pupae weight (g)	*Weight gain rate (%)	**20E titers gain rate after treated for 24 h (%)	Pupation rate	Adult emergence
Control	6.1d ± 1.67^b	0.243 ± 0.056^a	4.112 ± 1.578^a	−0.75% ± 0.151 ^a	83.33%	68.0%
2-TD	8.4d ± 2.01^a	0.192 ± 0.049^b	1.980 ± 1.619^b	−32.58% ± 0.21 ^b	45%	22.2%

*Weight gain rate, the larval weight gain rate 24 h post-treatment
**20E titer gain rate = [(the concentration of 20E after 2-TD treatment– the concentration of 20E before 2-TD treatment) / the concentration of 20E before 2-TD treatment] × 100%. Each column sharing the same superscript letter (a or b) for both treatment groups was not significantly different at P > 0.05
