K-strategist
- Reproduce slowly
- Resilient in adverse
conditions
- Compete effectively for
environmental resources, thus high survival
rate
|
|
|
| Egg |
- Flat oval translucent
- Laid directy on the
surface of the fruit, inconspicuously in
depressions of the rind
- Female lays eggs near
stylar end of fruit
|
Parasitized by
trigogramma
- Low humidity and low
winter temps causes high mortality of the
egg and first instar
|
| Larvae |
- Low humidity and low
winter temps causes high mortality of the
egg and first instar
- Larvae enter the fruit
through an injury point or a navel end
- The last instar leaves
the fruit via a frass filled (granular
excreta) exit hole and drops to the ground
on a silken thread or else emerges after the
fruit has fallen.
- Larvae is first creamy
white with a brown-black head
- It turns pink-red later
- and is 10 mm long
|
Infested fruit
falls from the tree three to five weeks after
penetration by the larvae
- Emerging larvae penetrate
the fruit and lead to fruit decay, premature
ripening and abscission
- The rind takes on a
yellowish – brown color around the exit
points the tissue collapse and decay
|
| Pupa |
Pupates in loose
soil |
Constructs a
silken cocoon incorporating trash and soil
particles |
| Adult |

- Forewings are mottled and
hindwings are paler, lighter, even color;

|
- Nocturnal = FLY AT NIGHT
