What are Thrips?

Thrips are small insects that commonly infest both indoor and outdoor plants. They cause harm to plants by feeding on their sap and chewing their tissues. These pests thrive in warm weather, and their population can grow rapidly if left unchecked. Due to their tiny size and quick multiplication, thrips can go unnoticed until they cause serious damage. Symptoms of a thrip infestation can be similar to those caused by other pests or diseases, so it’s essential to identify the source of the problem before attempting to treat affected plants. 

Lifecycle of Thrips

  • Thrips’ life cycle varies depending on the species and location.
  • Adults and larvae overwinter in plant debris, underground or inside bark.
  • In spring, females lay 25 to 80 eggs in plant tissue.
  • Thrips eggs hatch in 5 days and develop into adults in 2 to 3 weeks.
  • The average lifespan of thrips is 35 to 45 days.
  • During the growing season, 15 new generations can be produced.
  • Thrips can cause serious damage to plants, so early detection and proper management are essential to control their population.

Identification of Thrips in Home Garden

Identifying thrips in a home garden can be challenging due to their small size. One way to identify them is by shaking a plant over a blank sheet of white paper. Thrips will fall off, and their darker bodies will be visible on the white surface. Using a 10- to 15-power magnifying glass can help identify the pest. Sticky traps can also capture thrips for monitoring and identification in a home garden. It’s best to use blue traps as they are more effective for trapping thrips and can be easily seen against blue, a common color in most gardens.

Garden Plants which are affected by Thrips

Thrips can affect a wide range of plants in a home garden. Some commonly affected crops include beans, cabbage, carrots, cucumber, peas, peppers, potatoes, squash, strawberries, and tomatoes. Flowers in shades of white, yellow, and blue, such as begonias, chrysanthemums, gladiolus, and roses, are also susceptible to thrips.

Houseplants with broad, thin leaves, like alocasia, calathea, dracaena, and palms, are most at risk of thrip infestations. Woody shrubs and ornamentals like azaleas, hibiscus, magnolias, and viburnums can also be affected. Regular monitoring and early detection can help prevent and control thrips in a home garden.
