Embodiment 1

[0022] Dilute the lily essential oil extracted by the above method with an appropriate amount of acetone and mix it evenly with the mouse feed, configure the feed with a lily essential oil content of 10% by weight, and take German cockroach nymphs of the same age that are growing well and place them in a fresh-keeping place. In the box, put 20 mice in each fresh-keeping box, divide them into two groups: blank control (only fed with mouse feed) and feed with feed containing 10% concentration of lily essential oil by mass fraction, each group has 3 repetitions, and is raised until all eclosions become adults Finally, the body weight and body length of Blattella germanica were measured.

[0023] Table 1 Effect of lily essential oil on growth and development of German cockroach

[0024]

[0025] The results are shown in Table 1. When the concentration of lily essential oil is 10% by mass fraction, the body weight and body length of cockroaches can be significantly reduced, and ...

Embodiment 2

[0027] According to the method of embodiment 1 configuration lily essential oil content is the lily essential oil feed of mass fraction 30%, 35%, 40%, 45%, 50%, 60% six kinds of concentrations of lily essential oil respectively by the method for embodiment 1, feeds German cockroach by the method for embodiment 1, Raise for 8 days, and count the lethality of six concentrations of lily essential oil to German cockroaches. Corrected mortality rate (%)=(treatment mortality rate-control mortality rate) / (1-control mortality rate)×100%.

[0028] The result is as figure 1 It shows that when the concentration of lily essential oil is greater than 30%, the death of the German cockroach can be caused, and when the concentration is more than 50%, it can be 100% lethal.

Embodiment 3

[0030] According to the method of Example 1, a lily essential oil feed with a lily essential oil content of 30% by mass fraction was prepared, fed to Blattella germanica for 9 days, and the effect of lily essential oil on the activity of acetylcholinesterase in Blattella germanica was detected. Mouse diet was used as blank control.

[0031] The result is as figure 2 As shown, lily essential oil has a significant inhibitory effect on the activity of acetylcholinesterase in the German cockroach, and has an impact on the nerve signal transmission process in the cockroach.

Abstract

The invention discloses application of lily essential oil to preparation of a cockroach killing preparation. The invention finds that the lily essential oil has the activity of killing cockroaches, mainly a stomach poisoning effect, and the essential oil has no repellent effect on the cockroaches. After the cockroaches eat the lily essential oil with the concentration of 10%, growth and development of the cockroaches are significantly affected and significant decrease in the body weight and significant shortening of the body length are caused; the lily essential oil with the concentration of 30% or above has the significant stomach poisoning effect on the cockroaches, the cockroaches die significantly, and the acetylcholinesterase activity is significantly reduced; the lily essential oil with the concentration of 50% can achieve the lethality of 100%.

Description

technical field [0001] The invention belongs to the field of cockroach control, and in particular relates to the application of lily essential oil in the preparation of cockroach-killing agents. Background technique: [0002] Plant essential oil (essential oil) is a kind of plant-derived secondary metabolites, with a small molecular weight and can be evaporated with water vapor. It is an oily liquid substance with certain volatility. It has the advantages of wide sources, environmental friendliness and low toxicity. The concept of research and development of pollution-free pesticides is consistent, especially its pleasant smell and good volatility, which are more suitable for the prevention and control of indoor sanitary pests. Scholars at home and abroad have done extensive research on the insecticidal activity of plant essential oils. Deng Yecheng, Li Ruiyu et al. found that the essential oil of Solidago canadensis and Wedelia essential oil have contact killing, fumigatio...
