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 species (F 5 34.03; df 5 2, 47; P 5 0.0001). The
temperature-species interaction was signiÞcant (F 5
4.78; df 5 6, 47; P 5 0.0011). Numbers of eggs laid by
B. cucurbitae were not signiÞcantly different at 24,
35:24, and 29:188C; however, numbers of eggs laid at
29:18 were signiÞcantly greater than at 24:138C. Highest
numbers of eggs for all experiments were laid by B.
dorsalis at 29:188C. Numbers of eggs laid by B. dorsalis
at 35:248C were signiÞcantly lower than at the other 3
temperature regimes. Numbers of eggs laid by C. capitata
were also highest at 29:188C, and signiÞcantly
greater than at 35:24 and 24:138C. Each species differed
signiÞcantly at 24:138C. B. cucurbitae had lower
fecundity than B. dorsalis and C. capitata at 24 and
29:188C. The latter 2 species were not signiÞcantly
different at these temperatures. There were no signi
Þcant interspeciÞc differences in gross fecundity at
35:248C, which reßected signiÞcant decreases in gross
fecundity of B. dorsalis and C. capitata to levels close
to B. cucurbitae.
Net fecundity varied signiÞcantly with temperature
regime (F 5 9.34; df 5 3, 47; P 5 0.0001) and species
(F 5 11.70; df 5 2, 47; P 5 0.0001). The temperatureÐ
species interaction was signiÞcant (F52.79; df56, 47;
P 5 0.0249). Daily egg production varied signiÞcantly
with temperature regime (F 5 27.95; df 5 3, 47; P 5
0.0001) and species (F588.77; df52, 47; P50.0001).
The temperatureÐspecies interaction was signiÞcant
(F 5 2.86; df 5 6, 47; P 5 0.0221).
Expected Longevity. Female longevity varied signi
Þcantly with temperature regime (F 5 156.21; df 5
3, 47; P 5 0.0001) and species (F 5 113.44; df 5 2, 47;
