Embodiment 1

[0016] 1 Experimental materials and methods

[0017] 1.1 Source of test insects: The larvae of the tea looper were collected from the Bolanwan Base of the Tea Research Institute of Hangzhou Academy of Agricultural Sciences and raised in an intelligent artificial climate room at a temperature of (25±2)℃, a relative humidity of 60-80%, and a photoperiod of 12L: 12D, fed with fresh tea leaves. The 1-3 instar larvae were raised indoors for one generation and used for tea treatment after starving for 3 hours.

[0018] 1.2 Tested essential oils and pesticides: 95% of eucalyptus essential oil, atractylodes essential oil, bergamot essential oil, and mugwort essential oil were purchased from Junda Natural Perfume Oil Factory in Ji’an Jishui County, Jiangxi Province, and 2.5% cyhalothrin (Kongfu) was commercially available.

Abstract

The invention belongs to the technical field of tea garden plant protection, particularly relates to application of cajuput essential oil in preventing and controlling tea geometrid and further provides a synergistic pesticide composition containing the cajuput essential oil. The synergistic pesticide composition is composed of the cajuput essential oil and Kung Fu according to a proportion of 9-1:1-9. The inventor intensively studies activity of various plant essential oils to tea geometrid and effect of a compound of the essential oil and the pesticide Kung Fu on preventing and controlling tea geometrid, and experiment results find that the cajuput essential oil and a compound composition thereof have good prevention and control effect on tea geometrid. A theoretic basis is provided fordeveloping the cajuput essential oil into new pesticide.

Description

Technical field [0001] The invention belongs to the technical field of tea garden plant protection, and specifically relates to the use of eucalyptus essential oil in preventing and treating tea looper. Background technique [0002] Tea looper is a serious hazard in all major tea areas in my country. Due to its large food intake, it is prone to outbreaks. At present, the main tea areas are chemical control. With the development of society and the need to protect the ecological environment, low-residue pesticides and pesticides that do not pollute the environment have attracted great attention. The development and utilization of plant-derived pesticides has become a hot spot at home and abroad. Plant-derived pesticides are essentially chemical pesticides, but they are extracted from natural plants. They are environmentally friendly and are not easy to make pests resistant to pesticides. They can keep the pest population density under the allowable level of economic damage for a l...
