Research regarding biology of Western Maize Rootworm (Diabrotica virgifera virgifera Le Conte) in Satu Mare County.

Abstract

In Romania, the pest Diabrotica virgifera virgifera (Western Maize Rootworm) was spread, from the first recorded in the country (1996) from Arad Country, toward East and North-East, being recorded damages in maize fields. Experiments and surveys were conducted in maize field in Pir village, Satu Mare County, where the population of Diabrotica virgifera virgifera was increased during the last 3 years through adult attraction in maize monoculture field, following the globally used method. First the land was divided into 36 plots each plot was examined spread in field of Diabrotica virgifera larvae populations. Sowing was done on April 28, 2010. We followed the appearance of the pest, the larva and adult stage, in maize monoculture, to determinate the flight of adults, larvae hatch, registering the presence of larvae in the soil and then around plant roots, evolution of the number of adults/plant, as well as production data. Research which were done have the aims to give more knowledge about the biology of pest in North-Western Romanian conditions. There are no differencence between pest biology in Satu Mare County with data known from literature in Romania and any else in the world.
