They mine the leaves of their host plant. The mine consists of a long epidermal corridor with a well-marked central frass line. The mine is mostly lower-surface, but sometimes upper-surface, and rarely on the rind of the developing fruit. Citrus leaf miner larvae are thus protected from many topic insecticide treatments.
A leaf miner is any one of numerous species of insects in which the larval stage lives in, and eats, the leaf tissue of plants. The vast majority of leaf-mining insects are moths ( Lepidoptera ), sawflies ( Symphyta , a paraphyletic group which Apocrita ( wasps , bees and ants ) evolved from), and flies ( Diptera ).
This leads to plant damage in the form of wilting and chlorosis of the foliage, leaf drop, stunted growth, and sometimes the death of the plant. Fruits such as oranges become lumpy and discolored when the insect feeds on them, and they may fall off the tree. Insects packed with harvested fruits continue to feed, causing more losses during shipping.
Liriomyza trifolii, known generally as the American serpentine leafminer or celery leafminer, is a species of leaf miner fly in the family Agromyzidae. [4] L. trifolii is a damaging pest, as it consumes and destroys produce and other plant products. It commonly infests greenhouses and is one of the three most-damaging leaf miners in
The most serious pests are mealybugs that feed on citrus. Other species damage sugarcane, grapes, pineapple (Jahn et al. 2003), coffee trees, cassava, ferns, cacti, gardenias, papaya, mulberry, sunflower and orchids. Mealybugs only tend to be serious pests in the presence of ants because the ants protect them from predators and parasites. [2]
They are wingless and appear as ovoid shapes covered by a mass of white mealy wax. Males have a pair of wings and two long waxy tails and are capable of flight. The mature female lays eggs in an egg sack of white wax, usually in clusters on the twigs, branches, and bark of the host plant, and also on the plant's leaves and terminal ends.

Liriomyza sativae, commonly known as the vegetable leaf miner, is a species of insect, a fly in the family Agromyzidae. [8] The larvae of this fly mine the leaves of a range of vegetables and weeds, but seem to favour plants in the families Cucurbitaceae , Fabaceae and Solanaceae .
