Development and Survival. Developme

Development and Survival. Developmental stage
durations varied inversely with temperature regime
(i.e., average daily temperature) (Table 2). Egg, larval,
and pupal stages of all 3 species were markedly
longer at 24:138C than those reared at other temperature
regimes. C. capitata had the highest median
survivorship (lx) at every immature stage in every
temperature chamber, with its maximum at 24:138C
(Table 3). Median survivorship values through the
adult stage are presented in Fig. 1 aÐc. At the pupal
stage, survivorship of both Bactrocera spp. was below
50% at 35:248C. B. cucurbitae and B. dorsalis were
longer lived than C. capitata.
Reproductive Parameters. Preoviposition periods
varied signiÞcantly with temperature regime (F 5
44.32; df 5 3, 47; P 5 0.0001) and species (F 5 30.68;
df 5 2, 47; P 5 0.0001) (Table 4). Preoviposition
periods at 24:138C were signiÞcantly longer than at
248C. At the latter temperature, preoviposition periods
were signiÞcantly longer than those at 29:18 and 35:
248C, which were not signiÞcantly different. The preoviposition
period for C. capitata was signiÞcantly
shorter than those for both Bactrocera spp., which
were not signiÞcantly different.
Gross fecundity varied signiÞcantly with temperature
regime (F 5 9.16; df 5 3, 47; P 5 0.0001) and
