Abstract

The invention provides an attractant for coccinella septempunctata. The attractant for the coccinella septempunctata consists of the following raw materials: 280 to 370 grams of triple superphosphate, 50 to 67 grams of diammonium and 21 to 30 grams of plant ash, wherein the ash rate of ramie root to tamarix to diversifolious poplar in the plant ash is 1:1:1. The attractant for the coccinella septempunctata is prepared by the following steps of: crushing the triple superphosphate and the diammonium into powder; mixing the power and the plant ash; and adding 18 to 35 kilograms of water to stir uniformly and spraying the mixture. The attractant for the coccinella septempunctata is sprayed for twice every year and aims to induce the coccinella septempunctata and kill aphids in the cotton field, wherein the first spraying time is from the twelfth day to the fifteenth day in June and germinated fruit branches of cotton is protected from being infringed by the aphids; the second spraying time is from the twenty-eighth day in July to the first day in August and cotton bolls are protected from being infringed by the aphids; and the spraying temperature is between 28 and 30 DEG C. By the attractant, the yield of the cotton can be increased by 60 to 80 kg/mu. When the attractant is sprayed on melon and fruit, vegetable, red date trees, walnut trees, Pyrus sinkiangensis trees and apple trees, the technical effect of inducing the coccinella septempunctata to kill the aphids is achieved.

Description

The attractant of a kind of coccinella septempunctata

Technical field

The present invention relates to kill the aphid technology, coccinella septempunctata is implemented to lure, the orientation is specified in arrival that can be punctual, kills aphid, need not to use other agricultural chemicals; Spraying apparatus adopts common instrument for pesticide to get final product.

Background technology

Coccinella septempunctata is known by people already as the natural enemy of aphid, but killing aphid often needs the agricultural chemicals cooperation, eliminates aphis to the infringement of cotton plant for anti-, and early stage practical agricultural chemicals is best selection, certainly will produce to the people harm of pesticide poisoning like this; For insect protected produces same technique effect with controlling worm, the present invention conceives the method that the attractant of employing induces coccinella septempunctata to kill aphid and has one's own knack, and discloses by literature search, does not produce identical similar fileinfo.

After deliberation with the land for growing field crops field observation, usually aphid is that cause disaster July in morbidity in June (the land for growing field crops cotton field of arid biogeographic zone), and at this moment coccinella septempunctata enters and comes too late, and attractant adopts lead to spray or locate to spray, coccinella septempunctata is in time called in, and owing to being smell, adult is called in by collaborative larva simultaneously, increased quantity, have and kill, do not prevent it, effect is splendid; The preparation cost of this agent is taken 3.5 yuan/mu, really can make 60 kg/acres-80 kg/acres of Yield Increase In Cottons.

The present invention is to wheat, vegetables; Once finding aphid, adopt this attractant to induce the coccinella septempunctata aphid of going out on walnut, red date, bergamot pear, apple tree, effect is very ideal also.

Summary of the invention

The object of the invention is to: the attractant of the coccinella septempunctata that provides, strengthening coccinella septempunctata is the effect of natural enemy of aphid, adopts simultaneously the technique effect of lead, not only can prevent but also can control, for frontier has been expanded in biological control.

The present invention seeks to realize like this: the attractant of a kind of coccinella septempunctata, raw material is comprised of double superphosphate 280-370g, two ammonium 50-67g, ash 21-30g, and wherein in ash, the ash rate of wild flax, red building, diversiform-leaved poplar is 1:1:1; During preparation: double superphosphate and two ammoniums are ground into powder mix with ash, and add 18-35kg water mix, mix evenly can spray; Spray every year 2 times, purpose is that ladybug is implemented to lure, and the cotton field aphid is implemented to kill; The time that sprays for the first time is on June-15 on the 12nd, and the protection cotton sprouts fruit branch and is not subjected to the infringement of aphid, and the time that sprays for the second time is 28-August 1 July, and the protection cotton boll is not subjected to the infringement of aphid; Spray temperature 28-30 ℃; Spraying of this agent can make Yield Increase In Cotton 60-80kg/ mu.

Described attractant, this agent are to melon and fruit, and vegetables and red date, walnut, bergamot pear, apple tree implement to spray, and same the generation lures coccinella septempunctata to kill the technique effect of aphid.

Attractant of the present invention is implemented to induce in the mode of smell, and data statistics and observation experiment show, after cotton plant sprays 10-30 minute, larva and the adult in 1-2 age can be called in simultaneously, has enlarged population norm amount, namely produces the effect of the aphid of going out; As edible without worm, coccinella septempunctata was left away naturally in 3-5 minute, and is minimum to its injury, is the effective ways of developing ecology cotton, shows technological progress.

Embodiment

Comparative examples of the present invention is described further.

Embodiment 1

Get double superphosphate 370g, two ammonium 67g, ash 30g, add water 35kg; Wherein the ash rate of the wild flax in ash, red building, diversiform-leaved poplar is 1:1:1; Mix evenly can spray;

Embodiment 2

Take the 17kg capacity of agricultural spraying barrel as example:

Get double superphosphate 280g, two ammonium 50g, ash 21g, add 17kg water mix, mix evenly can spray; Wherein in ash, the ash rate of wild flax, red building, diversiform-leaved poplar is 1:1:1;

The time that sprays of above-mentioned medicament: the cotton pearl in land for growing field crops sprays 2 times every year; Spray for the first time June 12, ladybug is implemented to induce, enter the cotton field aphid is implemented to kill, the protection cotton sprouts fruit branch and is not subjected to the infringement of aphid, for the second time August 1, protects the peach of binding not encroached on;

Above-mentioned medicament spray temperature: 29 ℃.

Production application: used continuously this agent to spray 3,5 of agriculture one teachers in 2006-2009, effect is splendid, makes Yield Increase In Cotton 80kg/ mu.
