Embodiment 1

[0042] Preparation can kill the biopesticide of ovum: the saponin (Taiyuan Ruihefeng Science and Trade Co., Ltd.) of mass percentage 0.1% emamectin (Sigma U.S.), mass percentage 3% % of Ghanaian seed oil (Ghanaian seed oil is obtained from the Griffonia simplicifolia produced in Ghana, Africa through an extrusion oil press), 1% by mass of sorbitan (Sigma USA), 2% by mass of hydroxymethyl Cellulose (Sigma U.S.) and 0.01% by mass percentage of sucralose (Sigma U.S.) are mixed, stirred at 8000 rev / min, add the water of 88.89% by mass percentage, form homogeneous slightly turbid emulsion, obtain the ability to kill insect eggs of biopesticides.

[0043] (2) Detect the prepared biological pesticide that can kill insect eggs:

[0044] 100 pairs of cockroaches (wild cockroaches in Guangzhou City, Guangdong Province) were raised in wooden boxes of 1×1×1 meter. Mix the biopesticide prepared in this example with water at a mass ratio of 1:10, spray 10 ml to evaluate the number of surv...

Embodiment 2

[0049] (1) prepare the biopesticide that can kill worm eggs: the saponin (Taiyuan Ruihefeng Science and Trade Co., Ltd.) of mass percent 0.08% emamectin (Sigma America), mass percent 8%, 3% Ghanaian seed oil by mass (Griffonia simplicifolia produced in Ghana, Africa, produced by Griffonia simplicifolia in Africa), 3% ethylene glycol by mass (Sigma USA) and 1% hydroxyl Methyl cellulose (Sigma USA) was mixed, stirred at 10,000 rpm, and 84.92% by mass of water was added to form a homogeneous slightly turbid emulsion to obtain a biopesticide capable of killing insect eggs.

[0050] (2) Detect the prepared biological pesticide that can kill insect eggs:

[0051] 100 pairs of cockroaches (wild cockroaches in Guangzhou City, Guangdong Province) were kept in wooden boxes of 1×1×1 meter. Mix the biopesticide prepared in this example with water at a mass ratio of 1:10, use the spray method to spray 10 ml to evaluate the number of surviving cockroaches 10 days later, and evaluate the nu...

Embodiment 3

[0056] (1) prepare the biopesticide that can kill worm eggs: with the emamectin of 0.3% by mass percentage, the saponin of 3% by mass percentage, the Gardner seed oil of 3% by mass percentage, the pentaerythritol of 0.8% by mass percentage , 3% by mass percentage of hydroxymethyl cellulose, stirred at 5000 rpm, added 89.9% by mass percentage of water to form a homogeneous slightly turbid emulsion to obtain a biopesticide capable of killing insect eggs.

[0057] (2) Detect the prepared biological pesticide that can kill insect eggs:

[0058] 100 pairs of cockroaches (wild cockroaches in Guangzhou City, Guangdong Province) were kept in wooden boxes of 1×1×1 meter. Mix the biopesticide prepared in this example with water at a mass ratio of 1:10, use the spray method to spray 10 ml to evaluate the number of surviving cockroaches 10 days later, and evaluate the number of cockroach larvae after 30 days. Mectin is used as a contrast (the quality of emamectin used is equivalent to th...

Abstract

The invention discloses a biological pesticide capable of killing ova and a preparation method and application thereof. The biological pesticide contains emamectin benzoate, escin and griffonia seed oil. The biological pesticide capable of killing the ova is prepared by mixing emamectin benzoate, escin, griffonia seed oil, a polyalcohol nonionic surfactant and carboxymethylcellulose, and adding water during stirring to form homogeneous and slight turbid emulsion. The biological pesticide has the effect of expelling mosquitoes and obvious effects of killing pests in the living environment of people, such as cockroaches, termites and ants, wherein the killing rate is over 95 percent; besides adult pests, the biological pesticide can also kill the ova to prevent the reproduction of the pestsso as to greatly improve the pest killing effect, and overcomes the limitation that the main active ingredient in the formula, namely emamectin benzoate cannot kill the ova; and simultaneously, the biological pesticide can spread toxin to pest populations because of mutual lick habits of the ants and cockroaches.

Description

technical field [0001] The invention relates to a biological pesticide, in particular to a biological pesticide capable of killing insect eggs, a preparation method and application thereof. Background technique [0002] In recent years, people are more and more concerned about the adverse effects of ecological environment damage, poisoning of humans and animals, and target biological resistance caused by the extensive use of chemical pesticides. A new type of high-efficiency pesticide that is "friendly" to the environment and people has been expected by people. Biopesticides have the advantages of little impact on humans, livestock and the ecological environment, no pollution to agricultural products, strong pertinence to target pests, good protection of natural enemies of pests and resistance of pests, and are the most effective way to control pests and weeds one. [0003] Emamectin is a commonly used biological pesticide, which has the characteristics of ultra-high effic...
