Screening of natural products in the laboratory and the field for control of pollen beetles

Journal of Applied Entomology, 2013
AbstractPollen beetles, Meligethes spp. (Coleoptera: Nitidulidae), are among the most damaging pests of oilseed rape (Brassica napus L.). Increasing populations of pyrethroid‐resistant pollen beetles coupled with the prohibition of synthetic pest control products in organic farming means that other direct control methods are needed.

Impact of flower rewards on phytophagous insects: importance of pollen and nectar for the development of the pollen beetle (Brassicogethes aeneus)

Arthropod-Plant Interactions, 2018
Entomophilous plants reward pollinators with provision of nutrient-rich foods such as pollen and nectar. These rewards contain compounds that are essential to insect development and can be used by pollinators as well as herbivorous insects. The pollen beetle (Brassicogethes aeneus, syn.

Resistance of pollen beetle to pyrethroids and organophosphorus insecticides

2015
Prva pojava rezistentnosti repičina sjajnika na piretroide u Republici Hrvatskoj zabilježena je tijekom 2008. i 2009. godine (Gotlin Čuljak et al., 2012., Gotlin Čuljak et al., 2014). Od tada do danas, broj rezistentnih populacija repičina sjajnika povećava se na području cijele Europe.

Orientation and Feeding Responses of the Pollen Beetle, Meligethes aeneus, to Candytuft, Iberis amara

Journal of Chemical Ecology, 2004
The pollen beetle, Meligethes aeneus, which is an important pest of oilseed rape, Brassica napus, and turnip rape, B. rapa var. campestris, does not oviposit in all species of the Brassicaceae. The relationship between M. aeneus and candytuft, Iberis amara (Brassicacae), was investigated as part of chemical ecological studies into the development of ...

New species and records of pollen and sap beetles for Iran (Coleoptera: Kateretidae, Nitidulidae)

Zootaxa, 2017
During recent expeditions in North and Southwest Iran, 10 species of Kateretidae and Nitidulidae (Coleoptera) were found. One species of Kateretidae, Brachyleptus bicoloratus Reitter, 1896, and three nitidulid species, Afrogethes schilskyi (Reitter, 1897), Stachygethes khnzoriani (Kirejtshuk, 1979), and S. nigerrimus (Rosenhauer, 1856) are recorded for

Diversity of Beauveria spp. isolates from pollen beetles Meligethes aeneus in Switzerland

Journal of Invertebrate Pathology, 2012
Pollen beetles Meligethes aeneus were collected in oilseed rape fields at different sites in Switzerland in spring 2004-2005 and 32 isolates of the fungal genus Beauveria occurring as latent infections in the beetles were obtained and molecularly characterized. Three major clades, Beauveria bassiana sensu stricto (Clade A: n=13), Beauveriabrongniartii (

Laboratory and field response of the pollen beetle, Meligethes aeneus, to the odour of oilseed rape

Physiological Entomology, 1994
Abstract. The behavioural response of adults of the pollen beetle, Meligethes aeneus F. (Coleoptera: Nitidulidae), to the odour of one of their host‐plants, oilseed rape ( Brassica napus L.), was observed in the laboratory using a ...

Impact of ploughing on emergence of pollen beetle parasitoids after hibernation

Zeitschrift für Angewandte Entomologie, 1985
AbstractEmergence of Meligethes parasitoids from previous year's rape plots were recorded using emergence boxes. Three species were collected: Phradis interstitialis, P. morionellus and Tersilochus heterocerus. Catches from ploughed and fallow plots were compared.

Summary of findings from a participant country pollen beetle questionnaire

EPPO Bulletin, 2008
A questionnaire was sent to all participating countries to gain some background information on rape growing and on pollen beetle (Meligethes aeneus). Information was sought on the use of thresholds, the availability of active substances and on the year in which resistance, if present, had been observed.
