What does the spider mite like? - briefly
Spider mites prefer warm, dry foliage and feed on the cell contents of new leaves, buds, and stems. Elevated humidity accelerates their reproduction, whereas low humidity limits their survival.
What does the spider mite like? - in detail
Spider mites are attracted to specific plant species, climatic settings, and micro‑environmental conditions that support rapid development and reproduction.
Common host plants include:
- Cucurbitaceae (cucumber, melon, squash)
- Solanaceae (tomato, pepper, eggplant)
- Brassicaceae (cabbage, broccoli, cauliflower)
- Ornamental species such as poinsettia, hibiscus, and geranium
- Fruit trees like apple, peach, and citrus
Optimal environmental parameters are:
- Temperature: 20 °C–30 °C (68 °F–86 °F); development slows below 15 °C and mortality rises above 35 °C
- Relative humidity: 30 %–50 %; low humidity accelerates population growth, whereas humidity above 70 % reduces egg viability
- Light: bright, indirect illumination; excessive shade discourages activity
Feeding habits focus on:
- Undersides of leaves where protective silk webs are produced
- Young, tender tissue rich in chlorophyll and soluble sugars
- Stomatal regions that facilitate sap extraction
Additional influences:
- Air circulation that limits leaf surface moisture promotes colonization
- Nutrient‑rich foliage, especially with high nitrogen content, enhances reproductive rates
- Absence of natural predators (e.g., predatory mites, lady beetles) allows unchecked expansion
Understanding these preferences assists in monitoring and managing infestations effectively.
