Pink stem borer

Pink stem borer

Sesamia inferens

A species of Sesamia, Also known as Pink rice stem borer, Pink rice borer, Purplish stem borer, Purple borer, Ragi stem borer

Adorned with muted wing patterns that provide camouflage among the grasses and crops, pink stem borer is a creature of the dusk and dawn. This nocturnal insect's caterpillars are known for their voracious appetites, favoring the stems of cereal plants where they can cause extensive agricultural damage. Pink stem borer's biotic cycle encompasses remarkable transformation from larva burrower to an adult flier, subtly showcasing the complex relationship between an organism and its ecosystem.

Habitat Preferences of Pink stem borer Through Different Life Stages
The larvae of pink stem borer are primarily found in rice-growing regions, infesting and residing inside the stem of the rice plant. Pupation occurs within the stem or occasionally in the soil nearby. To search for eggs, inspect the upper and lower surfaces of young rice leaves. For searching larvae, look among the internal cavities of both damaged and undamaged stems, observing signs of frass. Pupae should be sought after in stems, just above the waterline, or within the soil at the base of the rice plants. Adults are nocturnal and may be encountered during the night around the rice fields or resting on foliage during the day.

When is the Best Time to Observe Pink stem borer
Most moths, including pink stem borer, are nocturnal, so the suitable time to find adults would be at night when they are most active.
Rectangle
What is the Best Weather to Observe Pink stem borer
Moths like pink stem borer prefer warm, humid nights without strong winds or rain, which can hinder their flight.

How and Where Can You Find Pink stem borer at Different Life Stages
Egg Pink stem borer eggs are typically laid on host plants. To locate them, inspect the underside of leaves on known host species for small clusters of eggs.
Larva Pink stem borer larvae can be found on or near their food source. In agricultural settings, look for them on or inside the stems of cereals or grasses, where they cause damage.
Pupal Pink stem borer pupae can be found in soil or leaf litter near the food source. Sifting through the top layer of soil or leaf debris can reveal the pupae.
Adult Pink stem borer adults can be trapped at night using a light trap, as they are attracted to light sources. Alternatively, a sweet bait trap can attract and capture them for observation or control.
