Characteristics: adult female body length 11.5-14.5mm, body width 5-7.5mm; male body length 10-13mm, body width 5-6mm. Body yellowish brown or dark brown, belly yellowish brown, dark clouds engraved fine point. Antennae 5, third, four are black or part black. The middle of the first child together with the end of the lateral lobe. Prompt thick section I, only the base surrounded by small buccal, is generally not close to the ventral surface of the head can be active; II is almost the length of the third and fourth section chief. Side of the front edge of pronotum pale, not a black ribbon, side angle slightly shorter, not sharp, not upturned. Males hold control triangle. Egg cylinder-shaped, high-l-1.2mm, width 0.8-0.9mm. Side of the central slightly swelled, the upper 1 / 3, and egg covered with a length ranging from dark processes, composed of net markings. Cover the eggs with white cilia around 11-17 roots. Tablets for the beginning of spawning white, beige gradient, until the orange-red. Newly hatched nymph to nymph beige, red compound eyes red, and 10 minutes later, head, chest, back and feet fade to black. The back of the yellow belly, there are four central spots of varying sizes, side wired with a blush colored spots sewn section 4 was seen after age 1 on the black wing buds. The average age of its body length, respectively 1.6,2.9,4.2,5.9,9.6 mm; body width 1.3,2.3,2.7,4,6. lmm.
Biology: Generations scorpion clams varies from region to region, in western Jilin Province occurred in 1 1-2 generations to adults in the winter under leaf litter. The end of early May the following year started its activities 4, 5 adults began to lay eggs in late winter, the old worms hatch in mid-June, early July the first generation adults appear in late July to lay eggs, the nymphs hatch in early August, the second generation in late August adult emergence of 10 months beginning in early winter. Overlapping generations often appear in July, the mid-winter can also see the first generation of adults and adults. In early July the eggs before the birth can be fully developed two generations, in early July after the birth of the eggs, can only complete one generation. In Hebei, mother give adults in leaf litter, clods and stones cracks winter. Started its activities in April the following year, in November to start in early winter, in each of 2-3 generations. Hi adult crawling, poor flying, summer activities at the prey in the woods Nongyin various insects. At a temperature of 25-30 ℃, relative humidity 70%, the adults begin mating 7-14 days after emergence. Mating life of about 24 times, up to 31 times. Began to lay eggs 3-8 days after mating. Eggs on leaves and prolific technical articles, the pairs arranged in rows or lines. Number of eggs per egg mass with particles ranging from grain to hundreds of thousands. 20 eggs per female lifetime of about 20-30 grains per spawning, the average fecundity was 300, up to 570. Spawning period and fecundity influenced by temperature, lower than 18 ℃, 40 ℃ higher than that are not spawning, 35 ℃ when the overwintering eggs that is only produced dozens of deaths. At 20-27 ℃ up to 100 days under the spawning period, the average fecundity is 465. In addition to temperature, also affect the fecundity of forage species, such as a feeding with gluten, eggs pernyi pupae was only raised to about 50%; and the juvenile fecundity of silkworm rearing lower. In adult life expectancy under 20-27 ℃ (from the winter after the date) was 110 days; high temperature significantly shorter life expectancy, at 35 ℃ for only 20 days. At a temperature of 25 to 30 ℃, relative humidity of 70% in 7 days after the eggs hatch, the hatching rate was about 90%. 5 instar nymph. Nymphs at 25 ℃ for 30 days, and at 30 ℃ only 21 days. 1 There is a group-living instar, 2nd instar after dispersing activities. Do not like the proliferation of food is sufficient, while in 7 days when the lack of food can be spread as far as 10m or so. Nymphs and adults of the same prey. |
