Rice thrips are more serious pests during the dry season. It infests the rice plant during the seedling stage or two weeks after early sowing. In direct-seeded rice fields in Malaysia, losses can reach 100% when infestation is severe in the first 20 days, after sowing.

Thrips are often considered pests for gardens, vegetable patches, and houseplants. Knowing about their lifecycle deal with them better. Key thrips lifecycle facts. Thrips are very small insects that are nearly impossible to see with the naked eye. They start out as rice-like eggs laid in small cuts or wounds in leaves, fruits, or stems of plants.

Both larvae and adults feed on young rice plants. Thrips injure plants by using a scraping mouth part to tear the leaf tissue, and then extract the plant liquids. This injury causes desiccation and is typically not a problem, except during dry, windy conditions.

Stenchaetothrips biformis is a species of thrips sometimes called the "rice thrips", a crop pest, is often described in the literature under the synonyms Baliothrips biformis [1] and Thrips oryzae.

Flooding to submerge the infested field for 2 days as a cultural control practice is very effective against the rice thrips. There are identified cultivars with known resistance to the rice thrips. Use resistant/tolerant varieties.

Thrips have been recorded as pests of rice from most of the rice-growing countries of the world in all rice environments. The two most com- mon species associated with rice are Stenchaetothrips (=Baliothrips, =Thrips) biformis (Bagnall) (Thripidae) and Haplothrips aculeatus (Fabricius) (Phlaeothripidae).

Aug 1, 2018 · The adult thrips are active in the day moving to look for young rice plant and other hosts. The life cycle of thrips is 10- 20 days and most of them live on rice or corn or weeds. It can exist in two forms; winged or wingless.

Nov 16, 2021 · Flooding the field to submerge rice for 2 days is an effective control strategy for rice thrips (Reissig et al., 1986; Pathak and Khan, 1994). In the Philippines, a method was developed to evaluate rice cultivars for resistance to rice thrips in the greenhouse (Nugaliyadde and Heinrichs, 1984b).

A pest of young rice seedlings. Adult and nymphs suck the cell sap from leaf tissues. Damaged leaves roll inwards along the margins, feeding cause leaf drying and leads to a poor crop growth.
