A stemborer (stem borer) is any insect larva, or arthropod, that bores into plant stems.

Stem borers can destroy rice at any stage of the plant from seedling to maturity. They feed upon tillers and causes deadhearts or drying of the central tiller, during vegetative stage; and causes whiteheads at reproductive stage.

The yellow stem borer is a pest of deepwater rice. It is found in aquatic environments where there is continuous flooding. Second instar larvae enclose themselves in body leaf wrappings to make tubes and detach themselves from the leaf and falls onto the water surface.

Stem borers in the genus Oberea are an Eastern United States pest of blueberries, blackberries, huckleberries, azalea, rhododendron, and laurel. The ½-5/8” long adults are slender long-horned beetles with yellowish brown heads and thorax.

ice stem borers are serious pests and of regular occurence infest the crop at all stages of crop growth. The rice plants can compensate the damage caused by the borers during the vegetative phase up to the stage of maximum tillering.

Scirpophaga incertulas, the yellow stem borer or rice yellow stem borer, is a species of moth of the family Crambidae. It was described by Francis Walker in 1863.

Use sex pheromone trap for the control of rice stem borer. Monitor through pheromone traps (@ 10 to 12/ha) for timely control measures. Change the lure at 15-20 days intervals.

Yield losses from rice stem borers depend on the nature of the rice variety, the timing of attack, and the composition of the stem borer species assemblage. This study uses a range of phenotyping methods to distinguish different categories of ...

Sep 26, 2024 · yellow stem borer is regarded as monophagous with exclusive host specificity to rice. The number of generations in a year can vary from 2 to 6, depending on the ecological conditions and the availability of rice plants. The life cycle of the yellow stem borer consists of four stages: egg, larva, pupa and adult.

Stem borers are difficult to control with insecticides because the larvae and pupae are inside the stem and they have overlapping populations in the field. Proper timing of insecticide application is critical to stem borer control.
