Table 3. Ovicidal toxicity of MB to three species of insect eggs.

Insect	n*	LC50 (95% CL) mg/cm2	LC95 (95% CL) mg/cm2	Slope ± SE
H. halys	270	0.020 (0.012–0.026)	0.048 (0.036–0.090)	4.36 ± 1.11
M. sexta	270	0.015 (0.011–0.020)	0.060 (0.042–0.112)	2.77 ± 0.46
P. xylostella	2100	0.001 (0.001–0.002)	0.005 (0.004–0.025)	7.32 ± 1.14

^*Number of eggs tested. 30 eggs/concentration and nine different concentration solutions (including blank control) were tested for H. halys and M. sexta. 300 eggs/concentration and seven different concentration solutions (including blank control) were tested for P. xylostella. DI water solution contained 0.5% Tween 20 (v/v) and 0.5% Tween 80 (v/v) was used as blank control.
