Passion fruit pests and control methods

Passion fruit pests and control methods

Passionflower Pests: Aphids

symptom

Aphids are the fastest reproducing insects, and can reproduce 10 to 30 generations a year. Female aphids can reproduce from birth and do not need males to reproduce.

Aphids use their mouth needles with sucking mouths to pierce the epidermis of plants and suck the juice from the tender leaves of the plants, causing the plants to grow slowly. The secretions of aphids also attract ants.

Prevention and treatment methods

When breeding, pay attention to regular ventilation and light transmission to prevent aphid infestation.

If the number is small, kill them manually and spray them with 1500 times diluted 80% DDT emulsion in the initial stage.

If diseased plants are found, they need to be removed and destroyed in a timely manner to prevent the pests from spreading further.

Passion fruit pests: Red spider mites

symptom

Red spider mites are relatively small and not easy to be found. They are reddish brown or orange in color. Once found, the damage they have caused is often already quite serious.

Red spider mites use their mouthparts to absorb nutrients from leaves, causing an imbalance in the plant's water metabolism and affecting its normal growth and development.

Red spider mites generally reproduce in an environment with higher temperature and lower humidity, and a single spider will do little harm to plants.

Prevention and treatment methods

Ideal prevention and control effects can be achieved by spraying 1000-1500 times diluted 40% dicofol emulsifiable concentrate, 2000 times diluted 20% acarb wettable powder, 2000 times diluted 15% cypermethrin emulsifiable concentrate, or 6000-8000 times diluted 1.8% cypermethrin emulsifiable concentrate.

Passion fruit pests: coffee borer

symptom

The larvae of the coffee wood borer will damage the trunks and branches, causing the parts above the damaged area to turn yellow and die, or be easily broken by strong winds, seriously affecting the growth and yield of the plants.

Prevention and treatment methods

Regular inspections should be carried out. When insect feces are found at the entrance of the column and below it, 100 times the concentration of DDT or omethoate should be injected with a syringe in time, and then the entrance should be sealed with cotton and sticky yellow mud to kill the pests.
