Change of life-history traits in the four melanic morphs ofBactrocera dorsalis
The preimaginal stages obtained from the four melanic morphs of B.
dorsalis adults had significant different pupation times (ANOVA:
F3, 116 =164.3, P<0.0001 ), emergence
time (ANOVA: F3, 116 =118.7, P<0.0001 ),
larval weight (ANOVA: F3, 116 =13.97,P<0.0001 ) and pupal weight (ANOVA: F3,
116 =19.45, P<0.0001 ). Larvae from morph 4 adults
which has less melanin (pale) took a long time to reach the pupal stage
as compared to those from the other morphs (Fig. 2A). Nonetheless,
adults from this morph emerged faster from the pupae followed by adults
from morph 1 (Fig. 2B). Larvae from morph 3 and 4 weighed less in
comparison to those from morph 1 and 2 (Fig. 2 C). However, only pupae
from morph 3 had a reduced weight; while pupae from morph 4 had the same
weight as those from morph 1 and 2 (Fig. 2 D).
