Cotton bollworm and tobacco budworm are among the most important insect pests of cotton. Timely identification of the insects is critical for efficient management of the pests to reduce cotton yield losses. Hel-ID developed by Agdia and Mississippi State University, can accurately identify both the bollworm and budworm in the egg stage. The ELISA kit based on monoclonal antibodies is simple to use and requires no special laboratory equipment or measuring devices. A large amount of egg samples can be tested in a relatively short time. Two-year results indicate that Hel-ID is 99-100% accurate in laboratory tests and 95-100% accurate in field trials. Therefore, Hel-ID can be a convenient tool for cotton producers and consultants allowing them to make bollworm and budworm management decisions precisely within hours.
