Pests of Jasmine_Identification_Dr.UPR.pdf

Jasmine plants can also be affected by various pests, which can damage the leaves, flowers, and overall health of the plant. Here are some common pests that affect jasmine:

1. Aphids
Description: Small, soft-bodied insects that are typically green, yellow, or black.
Damage: Aphids suck sap from the plant, leading to distorted leaves, yellowing, and sticky honeydew that can attract ants and sooty mold.
Control: Use insecticidal soap, neem oil, or encourage natural predators like ladybugs.
2. Whiteflies
Description: Small, white, flying insects that resemble tiny moths.
Damage: Whiteflies feed on the sap of jasmine plants, causing yellowing and wilting of leaves. They also excrete honeydew, which encourages mold growth.
Control: Use yellow sticky traps, insecticidal soap, or neem oil.
3. Mealybugs
Description: Soft-bodied, wax-covered insects that are typically white or pink.
Damage: Mealybugs feed on plant sap and cause yellowing, stunted growth, and a sticky residue (honeydew).
Control: Use neem oil, insecticidal soap, or rubbing alcohol applied with a cotton swab to remove them.
4. Spider Mites
Description: Tiny arachnids that are usually red or green.
Damage: Spider mites suck sap from the leaves, causing yellowing, stippling, and webbing around the plant.
Control: Spray the plant with water to dislodge mites, or use miticides or neem oil.
5. Scale Insects
Description: Small, immobile insects covered with a hard, waxy shell.
Damage: Scale insects suck sap from the plant, weakening it, causing yellowing of leaves, and potentially leading to leaf drop.
Control: Manually remove scales with a soft brush or use horticultural oil to smother them.
6. Jasmine Mite
Description: A type of spider mite specific to jasmine plants.
Damage: These mites cause stippling, leaf curling, and yellowing of the leaves.
Control: Apply a miticide or neem oil to the affected areas, and ensure good air circulation around the plant.
7. Thrips
Description: Tiny, slender insects that are usually yellow, brown, or black.
Damage: Thrips feed on the flowers and leaves, causing scarring, deformed petals, and black specks on flowers.
Control: Use insecticidal soap, neem oil, or introduce natural predators like predatory mites.
8. Caterpillars
Description: Larvae of moths and butterflies.
Damage: Caterpillars feed on jasmine leaves, creating holes or consuming entire leaves, which weakens the plant.
Control: Handpick the caterpillars or use Bacillus thuringiensis (Bt) to control them.
9. Ants
Description: Though not directly feeding on the plant, ants are often attracted to the honeydew produced by aphids, mealybugs, or scale insects.
Damage: Ants protect aphids and other pests, encouraging their spread.
Control: Use ant bait, or manage aphid and scale infestations to reduce ant attraction.

Female is cylindrical vermiform with two pairs of legs. Measures about 150-160 μ long
and 44μthick. This is mainly seen in mullaijasmine.
Severe infestation results in hair-like outgrowth(white velvety “erinium”) on the surface of
the leaves, tender stem and flower buds.
