Abstract
The invention discloses a method for loosely keeping the stiff aphids of sulzer braconid flies. The method comprises the following steps: picking the stiff aphids of the sulzer braconid flies togetherwith leaves, removing sulzers which are not parasitized on the leaves and loosely keeping by 3-4 batches in the entire tobacco growing season, wherein the balance period and the agglomerate period oftobacco plants are two key periods of loose keeping. The original population quantity of the sulzers in the field is controlled by releasing a large amount of stiff aphids of sulzer braconid flies atthe early period, and the population quantity of the sulzer braconid flies in the field can be effectively maintained by loosely keeping the stiff aphids continuously and loosely keeping the stiff aphids discontinuously, thereby achieving the aim of controlling the sulzers effectively. By releasing the sulzer braconid flies in a mode of the stiff aphids, the control action of the sulzer braconidflies on the sulzers can be enhanced, the control effect change caused by the fluctuation of the aphid quantity is reduced, and a stable preventing effect is achieved. The invention can reduce usage amount of sulzer pesticide by 50%, lower the residual pesticide in tobacco leaves, enhance the safety of the tobacco leaves, reduce the pollution of the pesticide to the environment and protect the ecological environment.
Description
Technical field
The invention belongs to the biological control of insect pests technical field, be specifically related to the bulk storage method of the stiff aphid of a kind of aphidius gifuensis.
Background technology
Aphidius gifuensis (Apidius gifuensis Ashmead) is the important parasite of cigarette aphid, all generally takes place in each cigarette district of China.At vega, aphidius gifuensis is obvious to the natural control action of cigarette aphid, and natural parasitic rate is usually between 20%～60%, Gao Shikeda Zhao 89.16%[Wanyuan, Ding Chuiping. aphidius gifuensis biology and application study thereof. zoological research, 1980,1 (3): 405 415; Chen Jiahua, official's treasured is refined, Zhang Yuzhen. the interrelationship study of aphidius gifuensis and cigarette aphid. and Chinese tobacco journal, 1996,3 (1): 8-12.].Aphidius gifuensis has the comparatively wide prospect of utilizing aspect the biological control of cigarette aphid, aspects such as the biology of relevant aphidius gifuensis, ecology and protection utilizations thereof have more research report, for the large-scale breeding and the application of aphidius gifuensis lays the foundation.Utilize booth, field hut to breed aphidius gifuensis in a large number, the process more than ten years apply Yuxi, Yunnan Yan Qu's, also form the technological process (aphidius gifuensis Ashmaed scale propagation technique CN101455190) of comparatively ripe a large amount of numerous honeybees.In order better vega cigarette aphid to be carried out continual and steady control, be necessary to set up a kind of science, standard, feasible aphidius gifuensis bulk storage technology.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, the bulk storage method of a kind of science, standard, the simple and feasible stiff aphid of aphidius gifuensis is provided.
Purpose of the present invention is achieved by the following technical programs.
Except as otherwise noted, percentage of the present invention is percetage by weight.
The bulk storage method of the stiff aphid of a kind of aphidius gifuensis may further comprise the steps:
1, the collection of the stiff aphid of aphidius gifuensis: when cigarette aphid on the cigarette strain blade is ossify the stiff aphid of formation by parasitism in a large number, the stiff aphid of aphidius gifuensis is adopted down together with the tobacco leaf sheet,, standby on the removing blade not by the cigarette aphid of parasitism;
Remove the cigarette aphid and adopt the artificial method of rejecting or killing with the insecticide of high-efficiency low-toxicity.
The described tobacco leaf sheet that has the stiff aphid of aphidius gifuensis places 4～8 ℃ to preserve down, and storage life is no more than 7 days.
2, the release of the stiff aphid of aphidius gifuensis
1. release time: release time and the burst size of the stiff aphid of aphidius gifuensis need to determine according to generation period and the generating capacity of cigarette aphid.It is preferable in the mode of a small amount of repeatedly continuous bulk storage to discharge the stiff aphid control of aphidius gifuensis cigarette aphid.In whole tobacco growing season, generally need be divided into the stiff aphids of 3～4 batches of bulk storages cigarette strain balance phase, group's phase, the stiff aphid control of prosperous long-term bulk storage cigarette aphid.The balance phase of cigarette strain and group's phase are two critical periods of bulk storage.
The stiff aphid of the 1st batch of bulk storage before and after the cigarette strain balance phase, generally after the cigarette transplantation of seedlings 5～15 days, when the cigarette aphid begins sporadicly to take place, the stiff aphid of bulk storage continuously, and strengthen the stiff aphid quantity of bulk storage one by one, the stiff aphid of the stiff aphid of bulk storage is 10～20: 1 with the ratio of cigarette aphid;
The stiff aphid of the 2nd batch of bulk storage is before and after a cigarette strain group phase, and generally after the cigarette transplantation of seedlings 25～35 days, by the ratio 2～3: 1 of stiff aphid with the cigarette aphid, the stiff aphid of bulk storage was 1 time in per 7～10 days;
The stiff aphid of the 3rd batch of bulk storage is prosperous long-term in the cigarette strain, generally behind field-transplanting 45～55 days.The bulk storage amount should determine that the stiff aphid of bulk storage was 1 time in per 7～10 days according to field aphid amount according to stiff aphid and the ratio 1～2: 10 of cigarette aphid.
The stiff aphid of the 4th batch of bulk storage is in cigarette strain squaring period, every the stiff aphid of 10～15 days bulk storages 1 time, mainly be to early stage effect maintenance and keep field aphidius gifuensis population, stiff aphid is 1: 20～40 with the ratio of cigarette aphid, if reaching the cigarette aphid, the effect of the stiff aphid control of bulk storage in early stage allows in the economic threshold of harm when following, no longer bulk storage deadlock aphid.
2. delivery mode: discharge stiff aphid and promptly hang stiff aphid blade, with standby stiff aphid blade (the stiff aphid blade of refrigeration is being put honeybee taking-up in preceding 1 day and is being placed indoor), per 5～10 leaves are tied up on the long bamboo bar of a 1.0～1.5m, be inserted in the vega, per hectare is provided with 60～90 and puts the honeybee point, appoints the stiff aphid emergence of aphidius gifuensis back freely to spread parasitic cigarette aphid.
With respect to prior art, the present invention has the following advantages:
1, controls land for growing field crops cigarette aphid initial population quantity as main control strategy with the stiff aphid of early stage a large amount of release aphidius gifuensis, suppress increasing of cigarette aphid population at the initial stage that field cigarette aphid is taken place with the stiff aphid of higher proportion bulk storage aphidius gifuensis, keep early stage vega that higher aphidius gifuensis population quantity is arranged.
2, continue the stiff aphid of bulk storage, can form the aphidius gifuensis population of many worms attitude in the field naturally, effectively keep field aphidius gifuensis population quantity, thereby reach the purpose of effective control cigarette aphid.
3, the mode with stiff aphid discharges aphidius gifuensis, can select the weather conditions of suitable aphidius gifuensis, regulates stiff aphid bulk storage amount and time, improves the control action of aphidius gifuensis to the cigarette aphid, reduces the control effect variation that the fluctuation of aphid amount causes, reaches stable preventive effect.
4, the stiff aphid of bulk storage aphidius gifuensis can effectively be controlled causing harm of cigarette aphid; control efficiency to the cigarette aphid reaches 79.4%～90.2%; reduce cigarette aphid insecticide usage amount 50%; reduce the persticide residue in the tobacco leaf; improve the safety of tobacco leaf, reduce insecticide to the pollution of environment, protected ecotope.
