Table 5. Parity rates and daily survival rates on sampled populations.

	East		West		Season
	Gully	Urban	Gully	Urban	Summer	Winter
Parous rate	0.646	0.765	0.630	0.740	0.561	0.810
P with i0 = 3.5	0.88	0.93	0.88	0.92	0.85	0.94

The daily survival rate (p) was calculated using the parous rate (M) and the time of the first gonotrophic cycle (i0) with the formula p = M∧(1/i0).
