Embodiment Construction

[0019] The present invention will be further described below in conjunction with specific examples, but it is not intended to limit the present invention.

[0020] The following is the recipe table for Examples 1-4.

[0021]

[0022]

[0023] The preparation method is: uniformly mix the active ingredient with the carrier, adsorbent, excipient, and preservative, pass through a 100-mesh sieve, and use the direct compression method to prepare tablets. The compression pressure is 10MPa-30MPa, and the diameter of the tablet is 15-25mm. , thickness 5-10mm, made into sustained-release tablets with good shape.

[0024] Take 2 of the above tablets and the sweet and sour liquid and put them into the lure cores of the traps, hang them randomly in the fields (orange orchards, vegetable gardens) and continue to lure them for one month without changing the lure cores. At the same time, the position of the trap was changed, and the investigation results are as follows:

Abstract

The invention discloses a long-acting tablet with high attractiveness to citrus fruit flies. The tablet is composed of the following components in percentages by weight: 30-50% of an active ingredient, 30-50% of a carrier, 10-20% of an adsorbent, 1-10% of an excipient, and 0.5-1% of a preservative. The tablet provided by the invention has better attracting effects on different types of male and female fruit flies, the attracting effect on bactrocera dorsalis, bactrocera tau, and bactrocera citri is better than that of a sugar vinegar liquid, and the tablet has the characteristic of a long effect-lasting period, wherein the attracting effect can last for 4 weeks or more, thereby greatly reducing the costs and labor intensity of field attraction prevention and treatment.

Description

technical field [0001] The invention relates to pest control medicaments, in particular to a long-acting tablet with strong attractiveness to fruit fly pests and a preparation method thereof. [0002] technical background [0003] Bactrocera (Tetradacus) citri (Chen), B. dorsalis (Hende1), and B. tau (Walker) are serious pests to fruits and vegetables. Citrus: In addition to citrus, Bactrocera citrus can harm more than 250 other hosts; Bactrocera can harm loofah, pumpkin, bitter gourd and other melon crops, and can also harm more than 70 crops such as citrus, nightshade, and mango. The adult fruit fly has strong flying ability and fast reproduction. It lays eggs under the skin of fresh melons and fruits. After hatching, the larvae sneak in the fruit and develop to maturity by feeding on the pulp, thereby eating the fruit or causing the fruit to be unripe. It turns yellow and gradually rots and falls off, losing its commodity and edible value. [0004] It is difficult to con...
