Spotted Cucumber Beetle

Spotted cucumber beetle is a major agricultural pest of North America. Another name for the spotted cucumber beetle is “southern corn rootworm”. Many Diabrotica species cause damage to field crops, especially corn, making these beetles a major agricultural concern. Because of the subterranean nature of their larvae, these insects are hard and expensive to control.

ABSTRACT The genome of Diabrotica undecimpunctata virus 2 (DuV2), a putative positive-sense, single-stranded RNA virus identified from the southern corn rootworm transcriptome, comprises 5,313 nucleotides, including a short poly(A) tail. The two open reading frames encode a nonstructural polyprotein (p156) and a putative capsid protein (p25).

AbstractA mixture of stereoisomers of the corn rootworm pheromones was synthesised via the Grignard coupling of protected bromohydrins with alkylcuprate as a key step. The synthesis of 8-methyldec-2- yl propanoate (I ), the northern corn rootworm Diabrotica longicornis Say pheromone, was achieved from pentane-1,5-diol in four steps with an overall yield of 35.1 % and 10-methyltridecan-2-one (II ), the southern corn rootworm Diabrotica undecimpunctata howardi Barber pheromone, was synthesised from octane-1,8-diol as commercially available starting material in five steps with an overall yield of 28.7 %.
