The scientific name Acronicta major Bremer is Lepidoptera, Noctuidae. Alias ​​mulberry Spodoptera, Swordfly, S. moth, Camphor gray spotted moth. Distribution of Northeast China, North China, Northwest China, East China, South Central and Southwest China.
The main mulberry, hawthorn, peach, plum, apricot, plum, orange, and citron are the important leaf-feeding pests in the mulberry garden.
Injurious features young larvae damage the lower surface of the mulberry leaves and leaf meat, residual epidermis, grow up after the Tsui eat leaves, residual main veins, when the full tree mulberry leaves to eat.
Morphological characteristics Adult body length 27-29mm, wingspan 62-69mm. Dark gray, belly gray; Forewing gray to gray brown, sword pattern black, wing-based sword pattern dendritic, end sword pattern 2, outer kidney pattern is a thicker short, near the trailing edge of a relatively slender, 2 are not The outer edge of the wings; ring gray and white smaller, black side; kidney gray-brown larger, with black edges; inside gray and black, the first half of the Department of twists and turns, the latter half of a single line, relatively straight and not obvious; Black, the outer line is a zigzag double line, the outer side is black, the inner side is gray, and the edge line is composed of a small black dot. After wings grayish brown. The head is gray-white, the frontal side is black, the antennae are filiform, the compound eye is black and spherical, the black side of the masks on each side of the athlete's foot, and the brown thorns on the belly of the zygomatic section are 3 columns. Oval flat head-shaped, yellow to brown, about lmm in diameter. Larvae body length 48-52mm, body black, dense yellow long, short hair and thick needles black short bristles. Black short bristles clustered on the body dorsal hair follicles, so the appearance of the top line, black, both sides and the body side is yellow, the body side hair tumor raised more obvious. Head, chest shield, chest with black luster; toe hook with a single sequence, 45-52; larvae a total of 6 instar, all age body color, markings slightly different. The ellipse is long, elliptical, 24-28mm long, 6-8mm wide, brown to dark brown, with 4 hooks at the end and more than 20 roots.茧 Long oval shape, thick and dense silk, gray to earth.
Living habits 1 generation per year, dipping in the trees under the soil and in the gaps between the terraces for diapause and overwintering, eclosion in early July of the following year, entering the peak period in late July, feeding after 5-6 days of feeding after supplementation Eggs and eggs are seen in the middle and late July. In early August, the spawning period is high. The egg period is 7 days. The larvae are seen in late July and enter the hatching period in the middle and early August. 30 to 38 days of larval stage, mature larvae in early September, the tree is growing and phlegm. Adults are mostly exhumed in the afternoon, concealed during the day, nocturnal activities, with phototaxis, chemotaxis. The eggs are prolific in the leaf surface of the young leaves on the proximal part of the shoot, ranging from tens to hundreds of pieces, and each female can produce 500-600 eggs. The newly hatched larvae clustered on the leaves of the larvae foraging on the epidermis and the leaves were nicked or holes, leaving only the veins, and the leaves could be eaten after the 3rd instar. The residual petioles, with branching and transformation, were harmful. Natural enemies mainly have S. zea.
Control methods (1) The larvae loosen the top soil layer around the trunk in front of the tree and trap the larvae to dig and eliminate the earthworms. (2) Set black light traps to kill adult worms and combine field management to kill cluster larvae. (3) Control of larvae during pesticide application. The larval outbreak period and the first generation of egg hatching are the key period for application. It can use 50% phoxim EC 1500 times or 25% icass or 50% chlorfenone, 50% yamone , 50% Malathion EC 1000x, 10% Broma EC, 20% Chrysanthemum EC, 20% Chloramine EC, 20% Fenpropathrin EC 2000x; 2.5% KF, 2.5 % of the enemy to kill the EC, 20% speed killing chlorinated 2000-2500 times, 2.5% Uranus EC 3000-4000 times and other pyrethroid insecticides or organic compound of pyrethrine and organic phosphorus.
