What pests need to be controlled when growing dragon fruit? How should dragon fruit pests be controlled? We ask experienced netizens to help explainDragon fruit is a tropical and subtropical fruit that likes light and tolerates shade, tolerates heat and drought, likes fertilizer and tolerates poor soil, and has few pests and diseases, so it is widely grown in Hainan, Guangxi, Guangdong, Fujian, Yunnan and other places. Zhongdi Network has compiled several control methods for the pests that are relatively likely to occur on dragon fruit. They are listed in detail below for netizens' reference.
The harm caused by termites and control methods:
If the dragon fruit plantation was previously planted with pine, termites may be more serious. Termites will directly gnaw through the stems of dragon fruit plants or eat the root mass, causing the injured tissue to yellow and rot upward. To control termites, 40% trichlorfon at 600 times can be sprayed on the plant roots, or termite medicine can be sprayed on the ant trails to kill the colony.
The harm caused by underground pests of dragon fruit and control methods:
Common underground pests in dragon fruit orchards include snails, slugs, ants, etc., which gnaw on the young branches of the plants. Ducks can be released in the orchard to eat the pests, or lime can be spread on the ground or at the tree base, or poison bait can be used to trap and kill them.

Control methods for pests during the flowering and fruiting stages of dragon fruit:
Aphids and scarab beetles will occur during the flowering or fruiting stage of dragon fruit. Biological control such as hoverflies can be used, or soapy water can be used with a writing brush to wipe them off, or chemical control can be used, such as spraying 10% imidacloprid wettable powder at 2000 times; spraying 1.8% abamectin at 3000 times; spraying 10% nicotine EC at 500~1000 times; spraying 50% pirimicarb wettable powder at 2500 times.

At the peak of scarab beetle reproduction, tea seed bran can be poured on the bed surface to drive their larvae out to the surface, and then let ducks eat them. Or Bacillus thuringiensis pesticide can be used for control.
If red and yellow spiders, scale insects, caterpillars, black cutworms, fruit flies, corn borers, etc. are found causing damage, when flower buds and new shoots have grown 3 cm, spray 90% trichlorfon, or 80% dichlorvos plus 40% omethoate each at 1000 times, spraying 2~3 times in a row, with an interval of 7~10 days.
The harm caused by fruit flies to dragon fruit and control methods:
When the fruit matures and the peel turns red, fruit flies will lay eggs inside the skin of the nearly ripe fruit, and the hatched larvae feed on the flesh, causing fruit cracking and fruit rot.
Fruit fly control methods:In winter or early spring, loosen and turn the orchard soil to reduce the insect population base; during the peak outbreak period, at night spray the tree canopy with pyrethroid pesticides at 2000 times, or 90% trichlorfon at 800 times plus 3%~5% brown sugar, spraying 3 times in a row with an interval of 7 days; small pieces of paper soaked in 97% methyl eugenol plus 3% naled solution (mixed at a ratio of 95:5) can also be hung on the trees to trap and kill adults, hanging 50 pieces per square meter, 2 times per month. Bag the fruit in the middle stage of fruit development to prevent adults from laying eggs.
