First Report of a Migratory Pest, the Fall Armyworm, (JE Smith, 1797) (Lepidoptera, Noctuidae) from Bulgaria.

The first occurrence of an invasive pest species, the fall armyworm ( Lepidoptera: Noctuidae), in Bulgaria is reported. Different trapping methods (black light trap, traps baited with semiochemical lures, and food attractants) were used to study Noctuidae assemblages in Bulgaria in 2023. Two males of were caught with sex pheromone traps in maize fields in Knezha, northern Bulgaria, in early November 2023.

Biocontrol potential of entomopathogenic nematodes against the grey maize weevil Tanymecus dilaticollis (Coleoptera: Curculionidae) adults.

The grey maize weevil, Tanymecus dilaticollis, is a polyphagous species, which is among the most important pests of maize in Southeastern Europe. The efficacy of commercial products with two species of entomopathogenic nematodes (EPNs), Steinernema carpocapsae and Heterorhabditis bacteriophora, was investigated against adults of the grey maize weevil under laboratory conditions. Nemastar®, containing S.

The Addition of a Pheromone to a Floral Lure Increases Catches of Females of the Click Beetle Agriotes ustulatus (Schaller) (Coleoptera: Elateridae).

Agriotes ustulatus is an economically important click beetle in Europe. A female-produced pheromone, (E,E)-farnesyl acetate, has been identified and is used for monitoring and detecting males. More recently, a floral lure targeting females with modest, but significant, activity has been described.

European corn borer (Ostrinia nubilalis Hbn., Lepidoptera: Crambidae): comparing the performance of a new bisexual lure with that of synthetic sex pheromone in five countries.

Background: Phenylacetaldehyde is a flower volatile and attractant for among others the European corn borer Ostrinia nubilalis. The addition of 4-methoxyphenethyl alcohol has recently been reported to increase O. nubilalis catches four to five times, yielding a bisexual lure for the species.
