Host preference of pumpkin beetle to cucurbits under field conditions

Host Suitability of Red Pumpkin Beetle, Aulacophora Foveicollis (lucas) among Different Cucurbitaceous Hosts

The red pumpkin beetle, Aulacophora foveicollis (Lucas) is a common, serious and major pest of a wide range of cucurbitaceous vegetables. It is injurious to the crops and cause severe damage to almost all cucurbits. The present study was conducted to find out the host suitability of red pumpkin beetle, Aulacophora foveicollis (Lucas) among different cucurbit hosts in the Laboratory and Field La...

Confirmation of bean leaf beetle, Cerotoma trifurcata, feeding on cucurbits

The objective of these studies was to assess the degree to which bean leaf beetle, Cerotoma trifurcata (Forster), will feed on cucurbits. In 2003, we documented an infestation of C. trifurcata in a commercial pumpkin field near Rosemount, MN, USA. To evaluate C. trifurcata feeding on cucurbits, we conducted laboratory no-choice and choice test feeding studies. In the laboratory, C. trifurcata f...

Hyalomma ticks: bovine resistance under field conditions as related to host age and breed.

Field collection of ticks from two breeds of cattle [Native breed (local) and purebred [Friesian)], showed that the number of ticks was higher on purebred than on native cattle. The susceptibility seemed to increase with the age of the animals. Furthermore, breed appeared to exert more influence than age. There was no correlation between the number of ticks associated with each animal, the anti...

Response of typha latiffolia to cutting competition and glyphosate under field conditions

Applying imidacloprid via a precision banding system to control striped cucumber beetle (Coleoptera: Chrysomelidae) in cucurbits.

The striped cucumber beetle, Acalymma vittatum (F.) (Coleoptera: Chrysomelidae), is a key pest of cucurbit crops throughout its range. A novel precision band applicator was designed to inject a solid stream of imidacloprid solution in-furrow directly over the seed during planting to reduce beetle leaf feeding on pumpkin, zucchini, and cucumber crops. In 2004 and 2005, bioassays at the cotyledon...
