Vegetable soup

Vegetable pods (Oeobia un-dalis = Phalaena undalis = Hellula undalis Fabricius), also known as Brassica campestris, radish sprouts, Brassica oleracea, Brassica juncea, heartworms, borers, cockroaches, etc., are classified as Lepidoptera, Codling moth Section. The main hazards are cruciferous cabbage, cabbage, mustard, and radish root vegetables.

Hazardous characteristics? The first instar larvae feed on the seedlings heart and leaves, spinning knot net, from time to time affect the growth of seedlings, in serious cases can cause seedlings dead, resulting in lack of seedlings cut off; old instar larvae in addition to eat the heart and leaves, but also foraging The stem and the root of the stem, and can spread bacteria soft rot, causing the rot of the vegetable dies. The worm is widely distributed in various vegetable areas in the country, especially in radish, cabbage, and cabbage.

Morphology? Adults are brown to yellow-brown, near-small moths. The body length is about 7 mm, and the wingspan is 16-20 mm; the forewings have 3 wavy grayish white stripes and 1 black kidney-shaped spot, and the grayish white halos surround the spots.

The mature larvae are about 12 mm in length, yellow-white to yellow-green, and have 5 gray-brown longitudinal stripes (back line, sub-line, and valve line) on the back. There are hairy tumors on the body segments, and the hairs on the mid-dorsal thoracodorsal back. A total of 12 tumors were stratified in a single row, and the tumors in the distal segment of the abdomen were double-rowed, with 8 in the front row and 2 in the rear row.

Life habits? The worms occurred in 3 generations (North China) ~ 9th generation (South China), mostly larvae spit silk soil particles or dead leaves do silk winter through the winter, and a few maggots overwinter. In the Guangzhou area, the worms can be harmed throughout the year and there are no overwintering phenomena. However, the number of worms is most frequent during the summer (from late August) to autumnal (late September). At this time, the larvae (before flower bud formation) take place. The victims are heavier; from September to November, the radish, especially early sowing radish victims, is heavy; the cabbages are relatively heavy from April to November. Where the autumn weather is hot and dry, it is conducive to the occurrence of rapeseed meal. If the seedlings are in the period of 2 to 4 leaves, the damage will be heavier. The adult insects are nocturnal, have a little phototaxis, spawn on the stems and stems, especially in the heart. Newly hatched larvae damage latent leaves, 3rd instar silk is conjugated to the heart, which hides the feeding hazards, and 4 to 5 instars can be invaded by the heart and petioles into the stem and marrow. Larvae have drooping drooping and leaf turning habits. Most of the mature larvae in the vicinity of the vegetable root soil or the soil for phlegm.

Control methods
1, combined with management, manual killing. When the seedlings and the seedlings are found, if it is found that the cabbage is entangled in the wire, it is ready to be killed.
2, timely spraying should be sprayed 21% killing fleas, or 40% fenvalerate 5 000 ~ 6 000 times, or 2.5%, in the early larval hatching and before the crucible heart (or the heart leaves have a screen). Kung Fu or 20% chrysanthemum 4,000 times, or 40% chrysanthemum emulsifiable concentrate, or 40% chrysanthemum cream 3 000 times, or 50% phoxim, or 50% bataan WP 1500 times Liquid, or 90% trichlorfon crystals, 80% dichlorvos EC 1000 times, or BT emulsion, or bacillus, or insecticide powder (microbial pesticides) 1 000 times. Alternately spray 2 to 3 times, every 7 to 10 days, spray evenly.
