Table 7.

LD₅₀s of semipurified TC on insects on day 5

Insect	TC dose (ng)	Mortality (n)^a		Significance level of the difference^b
Insect	TC dose (ng)	Treated	Control	Significance level of the difference^b
C. zealandica	50	17 (36)^c	0 (36)	<0.000 (1.268 × 10⁻⁶)
P. xylostella	30	18 (36)	2 (36)	<0.000 (3.867 × 10⁻⁵)
G. mellonella^d	35	18 (36)	2 (36)	<0.0002

Mortality is given as the number of larvae killed. n is the sample size in the treated group or in the negative-control group.

<0.000 significant difference at a 0.1% level (= 99.9% confidence level).

Some of the larvae reverted to healthy with resumption of feeding.

G. mellonella larvae were injected with semipurified TC into the hemocoel.
