Bawang merah (Allium cepa var. Aggregatum) is one of the vegetable commodities that are widely cultivated and have high economic value. Shallots are spices or flavoring dishes that are used daily and tend to be always needed. Another benefit of onions is as a traditional medicine.<\/p>\n\n\n\n

\"Onion\n\t\t\t\n\t\t\t\t\n\t\t\t<\/svg>\n\t\t<\/button><\/figure>\n\n\n\n

Shallots in Indonesia can be grown in the lowlands to high. However, for optimal growth, many plantings are carried out in Lowlands (0-450 MASL) with an air temperature of 25-32\u00b0C. Onions grown at high altitudes have a longer lifespan of 0.5 -1 months and less production. Onion plants need maximum sun exposure for good yields.<\/p>\n\n\n\n

Although shallots include superior vegetable commodities of high economic value, in its cultivation is not spared from the constraints. One of them is the attack of plant pest organisms (OPT). The following pests that attack onion plants (Table 1).<\/p>\n\n\n\n

OPT on onion plants is one important factor that needs attention because it is very influential on crop yields. One of the pests that need to be watched out for is leaf slicer because it can cause crop loss of 30-100% (Vegetable Research Institute). Therefore, efforts are needed to provide protection to plants so that there is no loss of crops.<\/p>\n\n\n\n

\"Liriomyza\n\t\t\t\n\t\t\t\t\n\t\t\t<\/svg>\n\t\t<\/button><\/figure>\n\n\n\n

Liriomyza chinensis or leaf-slitting flies were first found attacking onion plants in Brebes in August 2000. The larvae of the Leaf slicer fly are the phase that inflicts damage on the onion. The Leaf slicer attacks plants from the age of 2 mst (weeks after planting) to the eve of harvest. Leaf slicer attacks can reduce crop yields and even crop failure during heavy attacks. High attacks of leaf-slitting pests occur in the dry season.<\/p>\n\n\n\n

Leaf Slaters attack onion plants after planting until the harvest. damage the leaves of newly grown onion plants to old plants. In its life cycle, Liriomyza chinensis develops through several phases, namely eggs, larvae, pupae and imago or adult flies.<\/p>\n\n\n\n

Leaf Slitting Life Cycle<\/h2>\n\n\n\n

Leaf Slaters attack onion plants after planting until the harvest. In its life cycle, the Leaf slicer develops through several phases, namely eggs, larvae, pupae and imago or adult flies.<\/p>\n\n\n\n

1. Eggs<\/h3>\n\n\n\n

The eggs are clear white, measuring 0.28 mm x 0.15 mm. Fly eggs are laid in red onion leaves. Leaf slitting eggs lasts 2-4 days.<\/p>\n\n\n\n

2. Larva<\/h3>\n\n\n\n

The larvae are yellowish white and slit the mesophyll tissue of the leaves and then stay in the Leaf cavity. Leaf-slitting larvae consist of 3 instars lasting 6-12 days. After the 3rd instar the larvae emerge from the leaves and fall to the ground forming pupae.<\/p>\n\n\n\n

3. Pupa<\/h3>\n\n\n\n

Leaf-slitting pupae are often found attached to the ground or the inside of leaf cavities. The golden yellow to yellowish brown leaf-slitting pupae are 2.5 mm in size. The duration of the pupa phase is 9-12 days and then the pupa comes out to become an adult insect (imago).<\/p>\n\n\n\n

4. Imago \/ Adult Fly<\/h3>\n\n\n\n

The female adult Imago or fly Liriomyza chinensis has a body length of 2.39 \u00b0 0.02 mm and the male 2.00 \u00b0 0.07 mm (Nawin 2003). The female Imago lives for 6 \u2013 14 days and the male imago 3-9 days. The development of leaf Slaters from egg laying to hatching into larvae and developing into imago ranges from 18-22 days. Egg laying activity by imago generally occurs in the morning.<\/p>\n\n\n\n

Symptoms Of Leaf Slicer Infestation<\/h2>\n\n\n\n

Although the plant seems to thrive onion farmers remain worried about pest attacks in this dry season. Including being aware of leaf slitting pests that can attack plants at any time. Because the pest can attack onion plants and reduce crop yields.<\/p>\n\n\n\n
