The subject invention concerns new classes of insecticidally-active proteins and the polynucleotide sequences which encode these proteins. More specifically, insecticidal proteins of approximately 12-24 kDa and of approximately 12-14 kDa are used for controlling corn rootworms. The subject invention includes methods and transgenic plants for controlling Western Corn Rootworm and other coleopteran insects.

The present invention relates to a time-resolved fluorescent immunochromatographic assay rapid test kit for quantitative determination of the level of type I pyrethroid, which has the advantages of simple operation, rapid detection, and with high accuracy. The kit has a quantitative detection limit of 9.12 ng/mL for a type I pyrethroid sample. When the kit is applied to the detection of an actual sample of type I pyrethroid and by comparing the detection result obtained by HPLC, the kit has a coefficient of correlation of 0.986 (R.sup.2). Hence, the kit is applicable to the detection by using the actual samples of type I pyrethroid.
