Background technology
Bradysia odoriphaga, Bradysia odoriphaga Yang et Zhang, belongs to diptera, eye Sciaridae.The liliaceous vegetables such as main harm leek, shallot, onion, spring onion, garlic, also lettuce, green vegetables, celery etc. are endangered once in a while, being distributed in the ground such as Beijing, Tianjin, Shandong, Shanxi, Liaoning, Jiangxi, Ningxia, the Inner Mongol, Zhejiang, Taiwan, is one of primary pest of allium vegetables.Worm state has adult, ovum, larva, pupa, is gathered in the bulb of leek underground part and tender stem causes harm with larva.Newly hatched larvae is first caused harm the upper end of leek leaf sheath base and bulb.The young stem of spring, leek of mainly causing harm in season in autumn two causes rotten, makes fragrant-flowered garlic leaf withered and yellow and dead.The downward activity of larva in summer is eaten into into bulb, and severe one bulb rots, and whole pier leek is dead.
Life habit
A, fragrant-flowered garlic maggot larva are comparatively responsive to the humidity of environment, and the optimum humidity of survival is between 60% ~ 80%, and host's humidity is excessive climbs immediately from host, no longer takes food.Not high to temperature requirement, 20 DEG C ~ 25 DEG C is its optimum growth temperature.And although its adult likes dark and damp environment, humidity is greater than 70% and can not survives.Low instar larvae is liked taking food at leek stem foot and false stem place, and advanced age, mature larva was then liked living in soil.
B, olaiphage larva in Chinese Chive can secrete silk thread, tie rare vegetables silk screen, and adhesion host detritus, is gregarious in off the net taking food.
C, fragrant-flowered garlic maggot larva very keep in dark place, and high light shows as under stimulating and do not stop rolling and creep everywhere.
Morphological feature
Adult
Body is little, length 2.0 ~ 5.5 millimeters, wing expanse about 5 millimeters, body back of the body pitchy.Compound eye overhead becomes carefully " eye bridge ", and feeler is thread, and 16 joints, foot is elongated, brown, tibia end spinosity 2.Fore wing light cigarettes look, marginal nervure and auxilairs are comparatively thick, and hind wing deteriorates to haltere.Male worm is slight of stature slightly, and belly is more elongated, and end has a pair clasper, and female worm abdomen end is thick, has a point cercus for two joints.
Ovum
Oval, white, 0.24 millimeter × 0.17 millimeter.
Larva
Body is elongated, long 5 ~ 7 millimeters of body time aging, and a pitch-dark look glossy, body white, translucent, apodia.
Pupa
Exarate pupa, initial stage yellow-white, after turn yellowish-brown, sprout wings before grey black, head brassy, glossy.
Pests occurrence rule
Occur from generation to generation that 4 ~ 6 generations are not etc. from Tianjin to Hangzhou Bradysia odoriphaga year.Within 1 year, there are for 6 generations in Hangzhou, if temperature in late fall higher also the 7th generation of appearance, in general 12 months, generation in the last ten-days period the 6th larva troop in soil around the underground rhizome or bulb of shallot, leek and survive the winter, Second Year late Febuary starts to pupate, early March starts to occur emerging adult, mid-March is emergence peak, and early April is first brood of larvae occurrence in peak period, a generation occurs in later nearly one month.
Bradysia odoriphaga adult all can lay eggs round the clock, and under ovum originates in earth's surface soil block or in leek bulb and leaf sheath, large polylith produces, and minority is loose produces, egg laying amount 100 ~ 300 not etc., general about 200.Larva has Characteristics of Damage of trooping, generally 5 ~ 10 centimeters activities under soil, stings food bulb or underground cauline leaf, makes plant withered death, pupate after aging at bulb or root.The harm of general sandy soil is heavy, and adult is not good at circling in the air, so occurrence injury becomes regional, worm's ovum, larva or pupa often to be carried secretly to kainogenesis by its plant product such as green onion of the head of garlic, mud fragrant-flowered garlic, band soil etc. by long-distance communications.4 annual ~ June and 9 ~ November worm amount maximum, in the spring, autumn two hazard booms, the spring, season in autumn two main harm leek young stem cause rotten, serious make fragrant-flowered garlic leaf withered and yellow and dead.7 ~ the August in summer, by because of larva non-refractory arid and heavy rain, larva 31 DEG C time with regard to diapause, particularly sandy soil, soil is by solar radiation quick heating, and heavy rain easily makes soil compaction, all be unsuitable for larval growth to grow, so field worm amount is few, endanger also light.
