Abstract: This invention relates to transgenic turf grass having resistance to turf grass pest insects. Methods of producing such insect-resistant transgenic turf grass lines are disclosed. The invention further relates to the use of the insect-resistant transgenic turf grass to eliminate or reduce the usage of spray-on insecticides to protect the turf grass from insect damage.

Abstract: This invention is a method for constructing recombinant organisms that produce proteins lethal to the larvae of insects. Nucleotide sequences were isolated from Bacillus popilliae that encode two adjacent, putative genes; orf1 and cryhime1. The cryhime1 sequence was related to other Bacillus popilliae genes that encode proteins active against Scarabaeidae insect larvae. When these nucleotide sequences were transferred to Bacillus thuringiensis, a protein was produced that had a lethal effect on the larvae from Scarabaeidae insects. When the orf1 sequence was removed from the recombinant Bacillus thuringiensis strain, no protein active against Scarabaeidae insect larvae was produced, strongly suggesting that the orf1 sequences are required for expression of the cryhime1 gene.
