Comparing time‐lapse photography and traditional human observation in collecting crop pollinator visitation data Ajastetun valokuvauksen ja perinteisen suoran havainnoinnin vertailu kerättäessä tietoa pölyttäjien kukkakäynneistä viljelykasveilla

open access: yesAgricultural and Forest Entomology, EarlyView.
Time‐lapse photography with commercially available trail cameras provides a competitive alternative to direct human observations for documenting pollinator flower visits, but its performance varies between crops. In apple, the cameras recorded more diverse pollinator assemblages than the human observer due to larger temporal coverage of the camera ...

The influence of female oviposition strategy on sibling cannibalism in the ladybird beetle Harmonia axyridis (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2003
I hypothesized that sibling cannibalism is one of maternal investment in that a female controls sibling cannibalism. To test the hypothesis, I conducted a laboratory experiment and field observations to investigate sibling cannibalism in relation to ...

Histomorphology Structure of the Gastric Caecum, Midgut, and Malpighian Tubules in Adult Flatheaded Pine Borer Chalcophora mariana (Linnaeus, 1758) (Coleoptera: Buprestidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT The pine weevil is one of the largest species in the jewel beetle (Buprestidae) family found in Central Europe and Turkey. Chalcophora mariana is generally considered a secondary guest and primarily develops in weakened, decaying, or recently dead pine trees.

Persistence of deterrent larval tracks in Coccinella septempunctata, Cycloneda limbifer and Semiadalia undecimnotata (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2002
The persistence of oviposition-deterring effects of coccinellid and chrysopid larval tracks on females of three aphidophagous coccinellid species was compared.

Assessing Predator Activity on Clay Models in Response to Common Insecticides in Turfgrass

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Insecticides exhibited clear but time‐dependent effects on predatory activity, as reflected by impression types and density on clay models in turfgrass. Certain insecticides (bifenthrin, and in some cases acephate + imidacloprid, imidacloprid, chlorantraniliprole, and tetraniliprole) reduced total impressions shortly after application and again later ...

Demographic parameters of Diuraphis noxia (Hemiptera: Aphididae) and Hippodamia variegata (Coleoptera: Coccinellidae) recorded in the context of D. noxia infesting resistant and susceptible cultivars of wheat

open access: yesEuropean Journal of Entomology, 2015
The Russian wheat aphid (RWA), Diuraphis noxia (Kurdjumov), is a serious pest of small grains and can cause losses of about 80% in wheat yields. Chemical control is ineffective against this pest so the combined use of host plant resistance and biological

Parasitic wasp‐associated polydnavirus and venom affect arthropod community assembly on wild cabbage via the caterpillar host

open access: yesEcological Entomology, EarlyView.
Cotesia glomerata polydnavirus and venom, either alone or in combination, affect colonisation by members of the arthropod community in a natural field setting. Plants damaged by P. brassicae injected with both polydnavirus and venom were colonised more often by Mamestra brassicae caterpillars, Myzus persicae aphids and aphid parasitoids compared to ...
