Table 2. Comparison on the recapture rate and LT50 between non-chilled and post-chilled Aedes albopictus IHC males under semi-field condition.

Treatment	Replicate	No. of IHC males released	No. of IHC males recaptured	Recapture rate (%)	P value a	LT50 (days) b	P value c
Non-chilled	4	8000	1606 ± 326	20.1 ± 4.1	P < 0.0001	3.49	P = 0.3747
Chilled	4	8000	1963 ± 194	24.5 ± 2.4	P < 0.0001	3.40

^a: A linear relationship was observed between the daily SqRoot transformed number of IHC males captured and post-releases time if the P value was lower than 0.05 using regression analysis.

^b: LT50: Lethal time of 50% IHC males.

^c: Slope of equation was not statistically different between the non-chilled and chilled males if the P value was higher than 0.05 using ANOVA analysis.

All the results were presented as (Mean ± SEM).
