Life cycle of citrus leaf miner Nature of damage
Citrus leaf miner larvae feed by creating shallow tunnels, or mines, in young leaves of citrus trees. As the larvae feed a thin dark silver line appears just under the surface of the leaf. The leaves become discolored and wrinkled. Defoliation occurs if the infestation is severe. Encourage the incidence of citrus canker _x000D_ Life cycle:_x000D_ Citrus leaf miner has four life stages: Egg, larva, pupa, and the adult moth. The entire life cycle of the insect takes 3 to 7 weeks to complete._x000D_ Eggs:_x000D_ Eggs hatch about 1 week after being laid. Eggs are minute and flattened. The newly emerged larvae immediately begin feeding in the leaf._x000D_ Larva:_x000D_ Initially larvae produce tiny, nearly invisible, mines. As the larva grows, its serpentine path of mines becomes more noticeable. _x000D_ Pupae:_x000D_ The larva emerges from the mine as a prepupa and rolls the edge of the leaf over causing a curling of the leaf. Inside that curled leaf edge the leaf miner becomes a pupa. The pupal stage lasts from 1 to 3 weeks._x000D_ Adult:_x000D_ Adults do not damage plants and live only 1 to 2 weeks._x000D_ Control measures:_x000D_ Provide Buprofenzin 70.00% DF or Imidacloprid 17.80% SL or phorate 10% CG to the plants to reduce the infestation._x000D_ Source: AgroStar Agronomy center of excellence_x000D_ _x000D_ If you feel this information is useful to you, then click on the like button and share this with your farmer friends. _x000D_
