The term "stem borer" refers to the larvae of various insects, primarily beetles and moths, that bore into the stems of plants. These pests can cause significant damage to crops, weakening the stems, reducing yields, and even killing the plant. There are many different species of stem borers, each with its own preferred host plants and life cycle.
- Type of Infestation: Pest
- Common Name: Stem Borer
- Causal Organism: Melittia eurytion
- Affected Parts Of the plant: Stem, Leaf, Flower and Fruit
Environmental favorable factors for pests/Diseases:
- Warm temperatures: Most stem borers thrive in warm climates, and their activity often peaks during hot summer months.
- High humidity: Humid environments favor egg hatching and larval survival
Symptoms of Pest/Disease:
- Wilting: This is the most common symptom, and it can occur suddenly. The entire vine may wilt, or just one or two branches.
- Holes in the stem: You may see small holes in the stem of the plant, where the larvae have entered.
- Sawdust-like frass: This is the waste material of the larvae, and it may be seen around the base of the plant or near the holes in the stem.
- Yellowing leaves: The leaves of the plant may turn yellow and start to die.
- Stunted growth: The plant may be smaller than usual and not produce any fruit.
