How to control the peach fruit borer? A detailed guide to practical control methods
The peach fruit borer, also known as the peach stem borer or peach spotted borer, is an omnivorous pest found throughout the country. Its larvae damage the fruit or seeds of many fruit trees, including winter jujube, peach, plum, persimmon, chestnut, apple, pear, pomegranate and hawthorn. When fruit is damaged, it becomes filled with insect droppings and rots; in severe cases, the impact on both yield and quality is very great. Control methods: 1. In early spring, scrape the bark and plug tree holes. Use black light traps to kill adult moths. 2. During the adult emergence period and peak egg-laying period, spray a 1000-fold dilution of 50% phoxim, or a 1200-fold dilution of 50% dichlorvos emulsion, or pyrethroid pesticides. In the early stage of hatching of the first-generation larvae, spray a 1200-fold dilution of 50% fenitrothion or 40% dimethoate emulsion, then spray once more after 7 days; the effect is good. 3. Use 50% phoxim, or 20% pyrethrin, or 90% trichlorfon 0.5 kg plus 100 parts soil and about 10 g water, mix into a medicinal paste, roll into balls and plug the calyx tube. This not only controls the first-generation larvae but also the second- and third-generation larvae, with a effective period of 70-80 days. 4. Taking advantage of the peach fruit borer's strong tendency to lay eggs on sunflower flower heads, plant some sunflowers in the orchard; after they bloom, attract the adult moths to lay eggs on them, and spray the sunflowers with pesticide at regular intervals to kill the peach fruit borer. At the same time, this can also trap and kill pests such as the brown marmorated stink bug and the white-spotted flower chafer.
