Effects of close cutting on ground cover and quality of a polystand of Manilagrass and cool season turfgrasses

open access: yesItalian Journal of Agronomy, 2019
Warm season turfgrasses can be grown successfully in the transition zone, but dormancy occurs to some extent during the winter. Overseeding with cool-season turfgrasses is necessary if winter dormancy of warm season turfgrasses is not tolerated.

Metabarcoding of Pollen Carried by Syrphids Reveals Novel Plant–Pollinator Interactions in a Protected Natural Area and Agricultural Sites

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.

Sources of resistance to stem nematode, Ditylenchus dipsaci (Kuhn) Filipjev, in species of Medicago and Trifolium

open access: yes, 1992
The putatively resistant lucerne cv. Euver was as susceptible to 11 English and 11 French populations of 'lucerne race' stem nematode, Ditylenchus dipsaci, as the susceptible cv. Europe. The 'resistant' cv.

Microbiological Contamination of Honeys from Different Sources in Turkey

open access: yesJournal of Apicultural Science, 2018
Honey samples obtained by beekeepers taken from thirty-five different apiaries in Turkey’s region of Marmara were investigated for the presence of microorganism. Each honey sample was examined for the number of total aerobic mesofilic bacteria, coliforms,

Natural Parasitism of Nezara viridula (Linnaeus) (Hemiptera: Pentatomidae) by Trichopoda pictipennis Bigot (Diptera: Tachinidae) in an Organic Strawberry Field in Germany

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Natural parasitism of the invasive southern green stinkbug was recorded in an organic strawberry cropping system in southwestern Germany. The tachinid fly Trichopoda pictipennis shows successful establishment and field activity, indicating ongoing range expansion.

Honeybees directly outcompete other flower visitors through interference competition on shared resource

open access: yesEcological Entomology, EarlyView.
The outcomes of encounters between honeybees and other flower visitors were observed on two plant species. Pollinators either win, lose or share a resource. Competitive interactions led to greater than expected ‘wins’ for honeybees. The honeybee displaced or gave chase when interacting with another pollinator in at least 20% of winning outcomes ...

Is urbanisation a barrier to genetic diversity in the solitary specialist bee, Melissodes druriellus?

open access: yesInsect Conservation and Diversity, EarlyView.
Bees are integral pollinators commonly found in and supported by urban green spaces; however, their eco‐evolutionary response to urbanisation varies interspecifically. While several studies have explored the population and landscape genetics of bees in response to urbanisation, few have examined solitary or specialist species which may be more ...

Clover (Trifolium spp.) Inclusion in Kentucky Bluegrass (Poa pratensis) Lawns

open access: yesHortScience
Historically, white clover (Trifolium repens) seed was included in turfgrass seed mixtures to provide biodiversity and nitrogen (N) to lawns. White clover dicultures have been studied recently for inclusion in both warm- and cool-season turfgrasses, with
