Attractants for the green June beetle (Coleoptera: Scarabaeidae).

New replacement name for the species Scarabaeus (Scarabaeolus) nitidus Davis & Deschodt, 2015 (Coleoptera: Scarabaeidae: Scarabaeinae)--not an American pest.

In their review of the subgenus Scarabaeus (Scarabaeolus) Balthasar, 1965 (Coleoptera: Scarabaeidae: Scarabaeinae), Deschodt et al. (2015) described seven new species from Africa. One of these was Scarabaeus (Scarabaeolus) nitidus Davis & Deschodt, known by only twelve specimens from Botswana. This new name is preoccupied by Scarabaeus nitidus Linnaeus, 1758, a fact that was overlooked. The lat...

First Record of the Scarab Beetle, Phyllophaga lissopyge from South America, with Descriptions of Adult Seasonal Activity and Male Response to Sex Attractants

Phyllophaga lissopyge (Bates) (Coleoptera: Scarabaeidae: Melolonthinae) is reported for the first time from South America. Male sex pheromone response is described for P. lissopyge and two other co-occurring Phyllophaga species. Adults of P. lissopyge and P. menetriesi (Blanchard) flew to traps baited with methyl 2-(methylthio) benzoate whereas adults of P. obsoleta (Blanchard) flew irregularly...

Field evaluation of essential oils for reducing attraction by the Japanese beetle (Coleoptera: Scarabaeidae).

Forty-one plant essential oils were tested under field conditions for the ability to reduce the attraction of adult Japanese beetles, Popillia japonica Newman (Coleoptera: Scarabaeidae), to attractant-baited or nonbaited traps. Treatments applied to a yellow and green Japanese beetle trap included a nonbaited trap, essential oil alone, a Japanese beetle commercial attractant (phenethyl proprion...

Differential Susceptibility of Japanese Beetle, Oriental Beetle, and European Chafer (Coleoptera: Scarabaeidae) Larvae to Five Soil Insecticides

SPLAT-OrB reveals competitive attraction as a mechanism of mating disruption in oriental beetle (Coleoptera: Scarabaeidae).

This study compared the efficacy of SPLAT-OrB, a new pheromone formulation for oriental beetle mating disruption that can be mechanically applied, with hand-applied plastic dispensers in commercial blueberry fields. Both formulations were tested at 2.5 and 5 g of the major sex pheromone component (Z)-7-tetradecen-2-one per hectare, and evaluated by measuring trap shut-down, mating success of ca...
