mango hopper is a major insect pest of mango. The hoppers make holes and suck
the nutrients from soft tissues of panicles, leaves, flowers, fruits and fresh
twigs. Hoppers also release sweet liquid onto the leaves, on which a black
coloured fungus develops, which reduces the strength of the plant. Heavy attacks
cause curling and drying of infested parts. If young trees experience a severe
attack, they are much retarded while severely attacked older trees do not bear
fruit, which results in a complete loss of yield.
hoppers are brown in colour and are wedge or triangular in shape. The young
ones are similar in shape to the adult but vary in size and colour. Both are
very active and move sideways.
Hoppers are present all year
round in the orchard. Females lay eggs from February to March on flowers. Peaks in
population are observed during February to April and July to August.
of this insect pest should be largely based on cultural control rather than
chemicals because it’s been found that the hoppers have become resistant to
- Prune the plants so that the sunlight
can pass through the canopy and aeration can be improved
- Pruning should be done twice a year i.e.
after harvesting of fruit in September and at blossom in December/January
- No plant part or twig should intermingle
with the adjacent plant
- If population is still observed then
spray imidacloprid @ 0.3ml/litre of water at early stages of panicle formation
- Second spray with thiamethoxam @ 2g or acephate
1.5g/litre of water should be done at fruit set
When using a pesticide, always wear protective clothing and follow the instructions on the product label, such as dosage, timing of application, and pre-harvest interval.
