Medicinal plant pests

Deudorix eryx L. Lepidoptera, Lycaenidae. Distribution of Hunan, Guangdong and other provinces.

The host is Huang Zizi.

The larvae break into the flowers or fruits, and the interior tissues of the flowers and berries are left empty, leaving only the outer shells and seriously affecting the yield.

Morphological characteristics of adult female and male morphology are very different. Female butterflies are large in size, with black smoke on the front and green on the opposite side, and white markings and slender white tails on the trailing edge of the hind wings. The male body is slightly smaller, with blackish fins, blueish metallic luster, slender black tails on the hind wings, and white ends. Oval flat, with a depression in the middle. The surface is radiated in a radial pattern. It is grayish and grayish black before hatching. The last-instar larvae are yellow-brown, shiny and densely covered with black bristles. The brownish-brown spot on the thoracodorsal plate is nearly diamond-shaped. The 3rd and 4th sections of the abdomen are pale and mostly light green. There were 4 tumors on each section of the chest and abdomen. They were arranged in neat rows with black long bristles. Valve trim black. Yellow, white to yellowish brown, abdomen with a dark brown midline, white wings. Can see the veins.

Life habits 7 years old in South China. In the middle and early April of the following year, the larvae began to harm until October, 1 month and 1 year, and from April to May each year, the occurrence of the 1st and 2nd generation was large, and the damage was severe. Adults are active during the day and smoke nectar. Adults live 7-9 days. Adults often produce eggs in the head, ovary or fruit of the host's buds in the morning and evening. Some eggs are produced on the leaves, and the eggs are loosely distributed. Each flower has 1 grain, 2 eggs are individual, and the egg period is 3-4 days. Larvae often hatch at 8-10 o'clock, and hatch into yellow pods after hatching. During 13 days of larvae, all food and fruit were infested, and 3-4 years of age had large food intake and were transferred to harmful habits. In general, each larva eats 35 flowers and fruit, and there are cases of cannibalism.

Prevention methods (1) Spring from April to May, 1, 2 generation larvae hatching 1-2 years old, spraying 2.5% deltamethrin buttermilk oil or 20% killing buttermilk 2000-3000 times liquid. (2) The control period of this worm is short, and it is difficult to control the production. It is also possible to spray 1 dose and the same type of drug (1) in the initial stage of bud initiation, early flowering stage, young fruit stage, and mid-term result.
