Problems solved by technology

[0008] However, Aphidius imabilis can only parasitize aphids, and the reproduction cost is high. The survival time of adults of A. Aphid wasps lay eggs and parasitize. For tobacco crops, it can only control aphids, and the effect is relatively slow

Embodiment 1

[0030] The planting of embodiment 1 fennel

[0031] Fennel (Foeniculum vulgare Mill), also known as fennel, fennel, coriander, is a plant of the Umbelliferae family, which is in the same family as celery and carrots. Fennel is a perennial herb, the whole plant has a special spicy taste; the stem is erect, cylindrical, the root is taproot, potassium-loving, the root system is developed, deep into the soil, the leaves are filamentous, the leaves can reach 40 cm, and the plant height is about 2 meters , it is drought-resistant, salt-alkali-resistant, likes high temperature and strong light, is afraid of rain, has strong adaptability, and is not strict with the soil; it blooms yellow flowers in summer and autumn, compound umbels, and 5-15 cm umbrellas have 20-50 small flowers; Oval yellow-green fruit, the seed is in the shape of a rice grain, 4-9 mm long, with a specific aroma, and the young leaves can be used as vegetables; the fruit is used as spices and also for medicinal purpo...

Embodiment 2

[0041] Inoculation and propagation of embodiment 2 fennel aphid

[0042] In the experimental base, one of the species of aphids used to multiply ladybugs, the fennel aphid, was obtained from the Institute of Environmental Resources and Resources, Yunnan Academy of Agricultural Sciences in Panlong District, Kunming City, Zhuangke Experimental Base in Dianyuan Town, and Hongta Yuxi Manor ( Fengwo Garden) and other different propagation points collected fennel aphid specimens, and in August 2013, they were sent to the authoritative domestic aphid identification institution - the National Museum of Zoology, Institute of Zoology, Chinese Academy of Sciences (identifier: Professor Georg Xia) for identification of its species. They are five genera and five species of Aphididae, namely: Dysaphis foeniculus (Theobald, 1923), Cavariella aegopodii (Scopoli, 1763), cotton aphid Aphis gossypii Glover, 1877, carrot microtubule Aphid Semiaphis heraclei (Takahashi, 1921), aphid Hyadaphis cori...

Embodiment 3

[0046] Inoculation and breeding of embodiment 3 ladybugs

[0047] 1. Use scissors, writing brushes, test tubes, petri dishes, insect breeding boxes, etc. to collect ladybug egg masses (or make egg cards) from the crops where ladybugs are artificially propagated in the insect culture room and the supporting greenhouses or small sheds, Pupae and adults are cultured with moisture and transported to the fennel crops around the field ridges and open spaces around the tobacco fields that need to be artificially inoculated with ladybugs.

[0048] 2. According to the number of fennel aphids, 5 to 50 aphids per plant can be artificially inserted on the planted fennel plants, and the aphids can reproduce for 3 to 5 days.

[0049] 3. Connect the egg card / egg mass, pupa or adult of ladybug to the fennel plant of field planting, and multiply the population quantity of ladybug. : Aphids=1:50~300.

Abstract

The invention provides a method for preventing and curing tobacco pests by ladybird breeding via fennel aphids in field. The method comprises the following steps: planting fennels on the periphery (ridges and / or open spaces) of a land on which tobaccos are planted; by taking the fennel as a host plant used for aphid breeding and taking the aphids as food of ladybirds, carrying out amplification breeding to obtain the ladybirds used for preventing and curing myzus persicae and bemisia tabaci in tobacco fields via the cultivation of fennel plants, the breeding of the aphids and the inoculation and the breeding of the ladybirds, thus performing a continuous control function for the myzus persicae and / or bemisia tabaci which are important pests for tobacco crops. The method provided by the invention guarantees the security production of green tobaccos or organic tobaccos, and obvious economic, social and ecological benefits are obtained.

Description

technical field [0001] The invention relates to the field of biological control of agricultural pests, in particular to a method for using anise aphids to reproduce ladybugs in the field to control tobacco pests. Background technique [0002] In recent years, with the rapid development of modern tobacco agriculture, Yunnan Province is making every effort to create a "ecological, characteristic, high-quality, safe" tobacco leaf brand based on its unique ecological environment advantages. In this new development period, the biological control of tobacco pests and diseases is increasingly popular Widespread attention. [0003] Biological control is an important part of the integrated management system of crop diseases and insect pests. Among them, pest biological control refers to the method of using organisms and their products to control pests; including the traditional use of natural enemies (that is, "using insects to control insects") and the use of insect sterility, inse...
