Embodiment 1

[0017] Embodiment 1 Hydroxycitronellal propionate is to the test of cockroach repelling effect

[0018] Hydroxycitronellal propionate was diluted with absolute ethanol to a series of concentrations for activity testing, and the method was modified according to the method of Chris et al.

[0019] Cut the filter paper with a diameter of 15 cm in half into two pieces, one half piece of filter paper is used as a reagent carrier, and a mark is set on the filter paper; the other half piece of filter paper is used as a control carrier, without a mark.

[0020] Soak half of the filter paper as the reagent carrier with the prepared reagent, and soak the other half of the filter paper as the control carrier with the absolute ethanol solvent without reagent.

[0021] Dry the two half-sheets of filter paper, and after 5 minutes, smear the edges with solid glue, and paste them symmetrically on the inner bottom of the 18cm-diameter petri dish to prevent German cockroaches from drilling into...

Embodiment 2

[0034] Embodiment 2 Hydroxycitronellal propionate is used as the repellent of Tribulus chinensis

[0035] Hydroxycitronellal propionate was prepared into solutions with different concentrations of 0.5, 1, 2, 4, 8 (mg / ml) with absolute ethanol. The filter paper with a diameter of 9 cm was cut in half into two pieces, and half of the filter paper was used as a reagent carrier and soaked with a certain concentration of hydroxycitronellal propionate solution. Another half piece of filter paper was used as a control carrier, soaked with absolute ethanol. After drying, place in a petri dish with a diameter of 12 cm, and drop 20 Tribulus reds from the center of the petri dish according to the method of Example 1, and observe the number of Tribulus reds that stay on the treatment and contrast filter paper at different times. Each concentration was repeated 3 times. The test is carried out in a laboratory with a temperature of 25±2°C, a relative humidity of 60%, and a light of 13h / 24...

Embodiment 3

[0044] The test of the antifeedant activity of embodiment 3 hydroxycitronellal propionate to diamondback moth larvae

[0045] Hydroxycitronellal propionate was prepared into a 100 mg / ml stock solution with absolute ethanol, and then diluted with 5% Tween-20 water to a 10 mg / ml solution for testing.

[0046] A circular leaf disc with a diameter of 15 mm was made on several cabbage leaves with a manual puncher. The leaf discs were divided into a reagent group and a control group. The two groups of leaf discs were respectively treated with hydroxycitronellal propionate reagent solution and anhydrous Immerse in ethanol solution for 5s and dry on absorbent paper. In a petri dish with a diameter of 9 cm, wet filter paper was placed at the bottom, and 4 leaf discs of the reagent group and the control group were placed in each, arranged in a cross shape. The center of each Petri dish is a blank area. Put 10 pre-4th instar larvae of Plutella xylostella xylostella starved for 2 hours ...

Abstract

The invention relates to a kind of hydroxycitronellal propionate applied in insect repellent agent and antifeedant, including hydroxycitronellal propionate used as repellent agent of cockroach and red flour beetle, and hydroxycitronellal propionate used as antifeedant of diamondback moth larva. The bioassay result shows that, the repellent activity of 20 mg / ml hydroxycitronellal propionate against male Blattella germanica is up to 62%, the repellent activity of 100 mg / ml hydroxycitronellal propionate against female Blattella germanica is up to 65%. In field experiments, the hydroxycitronellal propionate also shows good effective. The repellent activity of hydroxycitronellal propionate against red flour beetle is also high, at 8mg / ml, after 12, 24, 72 hours, the repellent rate is above 90%; the antifeedant activity of the compound against diamondback moth larva is high, at 10 mg / ml, after 24, 48, 72 hours, the antifeedant rate is 86%, 77%, 67% respectively.

Description

technical field [0001] The invention relates to the application of a compound hydroxycitronellal propionate as an insect repellent and an antifeedant, and belongs to the field of pest control. technical background [0002] Since the emergence of organic insecticides, insecticides targeting the nervous system of insects have played an important role in pest control and have become the leading agents for pest control. Due to the neurophysiological similarities between vertebrates and insects, the targets of most pesticides also exist in humans and other vertebrates. Security is a threat. [0003] The long-term and large-scale use of insecticides has led to the rapid development of insect resistance. By 1988, nearly 500 pest species had become resistant to insecticides (Brattsten, 1989); by 2000, nearly 550 were resistant (Denholm et al., 2002). The rapid development of pesticide resistance not only makes pest control work difficult, but also causes more serious environmenta...
