Bee attractant, application thereof and method for attracting bees to pollinate tomato flowers

Abstract

The invention provides a bee attractant, application thereof and a method for attracting bees to pollinate tomato flowers. The bee attractant is selected from one or more of nonanal, 1-ethyl-4-isopropylbenzene and 4-ethylbenzaldehyde. Compared with common aromatic substances or flower juices or syrups of different plants, the bee attractant provided by the invention has stronger specificity for tomatoes and bees. The bee attractant is for smell learning training of a bee pollination swarm, the flower visiting rate of bees can be effectively increased, the tomato yield is increased, meanwhile,the labor intensity is reduced, and other diseases and pests caused by attractant spraying are avoided.

Description

technical field [0001] The invention relates to the technical field of bee pollination of crops, in particular to a bee attractant and its application and a method for luring bees to pollinate tomato flowers. Background technique [0002] Tomato is a large vegetable species with a wide planting area. In a relatively closed facility environment, it is necessary to artificially introduce pollinator species to pollinate tomatoes. In Europe, North America and other regions where the commercial bumblebee market is mature, bumblebee pollination has become an essential measure in the facility tomato planting industry. Although bumblebees have great advantages in pollinating facility tomatoes, there are still major problems in actual production: (1) It is difficult for a single pollinator bee species to satisfy the facility tomato markets around the world. In most countries and regions that cannot realize the commercial application of native bumblebees, they need to rely on import...

Problems solved by technology

Although bumblebees have great advantages in pollination of facility tomatoes, there are still major problems in actual production: (1) It is difficult for a single pollinator bee species to satisfy the facility tomato market around the world

However, in actual production, in the process of bees pollinating facility tomatoes, there are phenomena such as poor enthusiasm for nesting activities, low flower visiting efficiency, and unsatisfactory pollination effect, so bee attractants have emerged as the times require

[0004] In the prior art, the attractant formulations are mostly ordinary aromatic components, which are not targeted to different flower-visiting insects of different crops

Or the attractant formula is mostly flower juice or syrup of different plants, and the attractant is sprayed on the plant buds to be pollinated, but the attractant containing a large amount of sugar is sprayed on the plant, which is easy to cause various diseases of the plant. Also attracts other pests
