Control Methods for Mango Fruit-piercing Moth Pests and Diseases
I. Damage. The more serious pests include the fruit-piercing moth (Oraesia emarginata), the bird-beak fruit-piercing moth, the dead-leaf fruit-piercing moth, and the super-bridge fruit-piercing moth. The adult moths use their sharp mouthparts to pierce into the fruit and suck the juice of the flesh, causing the fruit to drop. Fruit pierced before harvest will rot during storage and transport. II. Morphological characteristics.

What are the control methods for the peach fruit borer on jujube trees?
Also known as the peach borer moth and peach spotted borer moth, it is an omnivorous pest distributed throughout the country. Its larvae damage the fruits or seeds of many plants such as winter jujube, peach, plum, persimmon, chestnut, apple, pear, pomegranate and hawthorn. When the fruit is damaged, it becomes filled with insect droppings, causing rot, and in severe

Important reasons why autumn shoots are the main fruiting mother branches of longan
Longan, like other subtropical evergreen fruit trees, grows new shoots throughout the year, and in the Fuzhou area it flushes 4-5 times a year: 1 spring flush, 1-2 summer flushes, 1 autumn flush, and winter shoots are less common, with large numbers of winter shoots emerging only under warm winter conditions. According to Huang Jinsong

How to increase the fruiting rate of loquat? Reduce humidity, cultivate fruiting mother branches, shape and prune, and apply additional fertilizer reasonably
Loquat is a fruit with high nutritional value. It is not only delicious and good in texture, but its leaves can also be combined with other medicines to make drugs. Therefore, loquat is welcomed by the market and people. In order to meet the needs of people and the market, the planting area of loquat is also becoming ⟦4 <p>Loquat is a fruit with high nutritional value. It is not only delicious and good in texture, but its leaves can also be combined with other medicines to make drugs. Therefore, loquat is welcomed by the market and people. In order to meet the needs of people and the market, the planting area of loquat is also becoming wider and wider. So how should the fruiting rate of loquat trees be increased? Next, I will share some methods for increasing the fruiting rate of loquat trees.</p><p></p><p><strong>Reduce humidity</strong></p><p>During the flower bud differentiation stage, loquat greatly needs a dry environment with high temperature and sufficient light. The flower branch bud differentiation stage of loquat occurs in summer, and there is more rain in summer, so drainage work must be done well at this time. In order to prevent water accumulation, drainage ditches must be made in low-lying areas with many pits. If the humidity in some orchards is too high, then when the leaves turn green, dig open the base of the loquat tree, expose the roots, and then cut about 80 percent of the branch roots into sections, thereby controlling nutrient dispersion, speeding up the greening of the leaves, and increasing the fruiting rate of loquat.</p><p></p><p><strong>Cultivate fruiting mother branches</strong></p><p>Because the fruiting branches of young loquat trees are all formed from summer shoots, the time, quantity, and growth capacity of summer branch bud sprouting are closely related to the fruiting rate of loquat. Therefore, a healthy and strong mother branch is the key to the number of fruits set, so in spring, after the new branches mature, fertilize in time to promote the sprouting of summer branch buds. During the fertilization stage, attention must also be paid to the amount, avoiding improper fertilization affecting the growth of loquat. Fertilization should be based on the growth stage of loquat, and the fertilizer is generally mainly phosphorus and potassium fertilizer.</p><p></p><p><strong>Shaping and pruning</strong></p><p>The pruning period of loquat is different from that of other fruit trees. Loquat is an evergreen fruit tree, so it cannot be pruned in winter like other fruit trees. Loquat pruning should be carried out in summer, immediately after the fruit is harvested. Because the summer branch bud sprouting is the most important one for loquat, it cannot be too late, otherwise it will affect the growth of flower buds. Autumn pruning of loquat is only an auxiliary pruning, carried out before the flower buds open in autumn. Fruit tree pruning can reduce the occurrence of pests and increase the nutritional development of the fruit tree, thereby improving the fruiting rate of loquat.</p><p></p><p><strong>Apply additional fertilizer reasonably</strong></p><p>Loquat needs sufficient nutrients, so during the fertilization process, the demand for phosphorus and potassium is relatively high. Therefore, the proportion of phosphorus and potassium fertilizer can be increased in fertilization, and the use of nitrogen fertilizer can be reduced. Because excessive use of nitrogen fertilizer will cause loquat to grow too fast and have excessive nutrients, seriously affecting the production volume of loquat. Therefore, use fertilizer reasonably, increase the proportion of phosphorus and potassium fertilizer, and improve the fruiting rate of the fruit tree.</p>

Identification and Control Methods for the Carambola Fruit Borer Moth
The carambola fruit borer moth is commonly known as the red-line worm. Its larvae occur in large numbers during the flowering period and invade the small flowers to feed on the stamens. The peak occurrence period is usually from late June to early August, and the damage is most severe in extremely hot weather. All the damaged small flowers drop off, often causing crop failure. During the summer full-bloom period, trichlorfon 1000x solution can be sprayed continuously every 5 to 7 days to kill the pests.

Control methods and key technical points for the peach fruit moth
(1) Manual and physical control. Scraping bark to destroy pupae: during the dormant season of winter jujube, manually scrape off the coarse bark and scaly bark on the trunk and branch forks; beforehand, spread plastic sheeting under the tree to collect the bark and cocoons, then pour boiling water over them in a centralized manner. Blacklight trapping of adults: during the adult emergence period, set up blacklight lamps (insect-killing lamps) to trap and kill adults. From May to June, remove the moth cocoons missed by chemical control. From early September, tie grass bundles at the trunk and branch forks to attract the insects for pupation, then take them down and burn them. (2) Chemical control. The key is
