Embodiment 1

[0034] Embodiment 1: Straw is laid in the citrus orchard to lure and kill nymphs.

[0035] 1. Selection of citrus orchards In the sandy red-yellow soil mountainous area, 50 citrus trees aged 16 years were selected.

[0036] 2. Laying straw In November, lay 15kg of straw at the base of each tree trunk within a diameter of 2m.

[0037] 3. The method of catching nymphs In late June, stick a piece of scotch tape about 6 cm wide on the trunk of each tree 20 cm above the ground.

[0038] 4. When to capture: From late June to late August, from 6:30 to 8:30 every night, catch the nymphs crawling under the tape, and then put them into a plastic bucket filled with water to kill the nymphs and prevent them from emerging.

[0039] 5. Cultivation and management of citrus orchards In case of drought and long sunny weather, in order to facilitate the nymphs to unearth and climb trees, especially during the period from late June to July 15, they need to be watered every few days. Other cu...

Embodiment 2

[0041] Embodiment 2: Huyou garden ditch fertilization to lure and kill nymphs.

[0042] 1. Garden site selection In Jinqu red-yellow soil area, with sandy mountainous areas, choose a place where the black cicada has caused serious damage over the years, and 100 pomelo trees with a fruit tree age of 18 years.

[0043] 2. Digging ditches and fertilizing fences In December, dig a circular ditch about 30 cm deep around each pomelo tree 1m away from the trunk, apply 30kg of fence fertilizer, and cover it with soil.

[0044] 3. Catch nymph method with embodiment one.

[0045] 4. The timing of capture is the same as that in Embodiment 1.

[0046] 5. Cultivate and manage with embodiment one.

[0047]The implementation results show that the effect of applying fence fertilizer to attract and kill nymphs in Huyou orchard is significant. An average of 153 nymphs were caught per Huyou tree per year, which was 566% of the control (27). The fruit yield per mu in the Huyou orchard incre...

Abstract

The invention discloses a method for luring, catching and killing citrus black cicadas. A feasible method for luring, catching and killing nymphs does not exist at present. The method comprises the steps of laying straws and applying barnyard manure in furrows around citrus trees or pomelo trees according to life habits of black cicada larvas and nymphs, creating appropriate soil conditions and living environments and then luring, catching and killing the nymphs. The luring rate is improved by more than double through comparison. Simultaneously, the catching and killing time and measures of lured nymphs are limited and stipulated strictly. The yield of citrus orchards (or pomelo orchards) and nearby citrus orchards is improved by 19%-28.5% through comparison after the nymphs are lured, caught and killed. Furthermore, the income gained by selling the nymphs can be increased, and the economic benefit is obvious.

Description

technical field [0001] The invention relates to a method for luring and killing citrus pests Cryptotympana atrata Pabricius, in particular to a method for luring and killing nymphs of Cryptotympana atrata Pabricius, reducing the degree of damage and increasing the yield of citrus. Background technique [0002] Black Grasshopper Cicada (Cryptotympana atrata Pabricius), also known as Grasshopper Cicada, Cicada, etc., belongs to Homoptera, Cicadae. Adults in summer feed on the sap of citrus twigs, often causing a large number of fruit drop and twig death. In orange orchards where black grasshopper cicada re-emerged, the plant damage rate reached 100%, causing large losses. [0003] Adults are black or dark brown, shiny, with a lifespan of 60 to 70 days. It appears from May to August every year, and when the average temperature reaches 22°C, the chirping of cicadas begins. Females lay eggs in the xylem of branch shoots from June to August (usually in the summer and autumn sho...
