Fruitspotting bug
Amblypelta lutescens lutescens (Family Coreidae)
Description:
Eggs: Pale green and wedge-shaped. Size: 2 mm in length.
Immatures: Nymphs have a black head with long antennae and a light
green tear-drop shaped body with a red patch and two black dots.
Adults: Light green with a light brown back (which includes the folded
wings). Size: 15 mm in length.
Life Cycle: Eggs are laid singly on young shoots and leaf petioles.
Once hatched the nymph goes through five instars before moulting
into an adult. Development from egg to adult takes approximately
40–45 days. There may be 4–5 generations per year.
Similar to: The damage may appear similar to that of tea mosquito
bug.
Damage: Nymphs and adults suck sap from shoots and young fruit.
When new pink shoots are attacked they wilt and die. Symptoms of
attack in green shoots and young fruit are black marks where feeding
has taken place. These marks later appear as elongate brown lesions
which crack as the shoot or fruit expands during growth.
Critical Control Period: Periods during the late wet season and early
dry season when leaf flushes appear.
Monitoring: Check young shoots for lesions at least once a week.
Adults and nymphs are difficult to find.
