Method for trapping and controlling bemisia tabaci in cotton field

Abstract

The invention relates to a method for trapping and controlling bemisia tabaci in a cotton field. The method comprises the steps: planting eggplant seedlings on rows of the cotton filed so as to trapping bemisia tabaci, and performing pesticide application control and biological control on bemisia tabaci of eggplants. Large-area pesticide application in the cotton field is reduced, so that prevention and control cost is reduced and the method is environment-friendly. The method has relatively strong practicability and operability and is simple and feasible; large-area pesticide application in the cotton field is reduced, so that prevention and control cost is reduced and the method is environment-friendly and is easy to promote. Meanwhile, eggplants can be used as vegetables, thus multiple things at one stroke are obtained.

Description

technical field

[0001] The invention relates to insect trapping and killing technology, in particular to a method for trapping and controlling Bemisia tabaci. Background technique

[0002] Bemisia tabaci (Gennadius) is widely distributed in all continents except Antarctica, and is an important pest in tropical, subtropical and adjacent temperate regions. Bemisia tabaci harms my country's grain, cotton, oil, vegetables, fruits, flowers and other cultivated plants as well as a variety of weeds. Its hosts are complex and diverse and widely distributed. It mainly breeds and harms in greenhouses in winter and early spring. After the temperature rises, summer and autumn The season is primarily a breeding hazard outdoors. Bemisia tabaci mainly damage plant leaves and feed and reproduce on the shady surface of leaves. The harm of Bemisia tabaci to cotton is mainly in the middle and late stages of cotton growth. After harming the leaves, the leaves will lose their chlorosis. produc...

Examples

Embodiment 1

[0034] This example provides a method for trapping and controlling Bemisia tabaci in cotton fields.

[0035] During the growth period of cotton, eggplants are planted on cotton rows to trap Bemisia tabaci and control Bemisia tabaci on eggplants.

Embodiment 2

[0037] This example provides a method for trapping and controlling Bemisia tabaci in cotton fields.

[0038] During the growth period of cotton, eggplants are planted on the cotton rows in the cotton field to trap Bemisia tabaci and control Bemisia tabaci on eggplants. Eggplant seedlings were planted on the cotton rows at intervals of 15 rows, and 1 eggplant was planted at intervals of 2m in the cotton rows for planting eggplants.

Embodiment 3

[0040] This example provides a method for trapping and controlling Bemisia tabaci in cotton fields. The method of planting eggplant on the cotton row in the cotton field is the same as embodiment 2, wherein after the emergence of cotton, plant three-leaf stage seedling eggplant seedlings on the cotton row at every interval of 10 rows, and plant 1 tree at intervals of 2.5m in the cotton row of planting eggplant eggplant. The method of controlling Bemisia tabaci on eggplant is once every 7 days during the occurrence period of Bemisia tabaci.
