Genetics, cross-resistance and realized heritability of resistance to acetamiprid in generalist predator, Chrysoperla carnea (Steph.) (Neuroptera: Chrysopidae)

Egyptian Journal of Biological Pest Control

Table 4 Direct test of monogenic inheritance of resistance to acetamiprid by comparing expected and observed mortality of the backcross (F₁♀ × Lab-PK ♂) of Chrysoperla carnea

Concentration (μg mL⁻¹)	Number of larvae tested	Observed mortality	Expected mortality^a	x²(df = 1)	P^b
1000	80	0.075	0.69	175.52	<0.001
2000	80	0.20	0.72	203.02	<0.001
4000	80	0.35	0.82	357.53	<0.001
8000	80	0.62	0.88	550.04	<0.001

^aExpected mortality at given dose = 0.5 (total number of F₁ larvae killed + number of Aceta-SEL larvae killed)/no. exposed in backcross
^bProbability values were considered significantly different at p < 0.05
