Characterization and Identification of Temperature and Humidity Properties of Varied Winter Covering Techniques for Wine Grapes in the North Foothills of the Tianshan Region

open access: yesApplied Sciences
Overwintering frost damage is a major challenge for the wine grape industry in northern China. This study investigates overwintering treatments to improve survival rates and mitigate frost damage in the wine grape production area of the northern ...

Mating Status Influences Cold Tolerance and Subsequent Reproduction in the Invasive Ladybird Harmonia axyridis

open access: yesFrontiers in Ecology and Evolution, 2017
Among arthropods, ability to survive cold conditions may be instrumental for species invading temperate or colder climatic zones. Cold tolerance can be influenced by multiple environmental and physiological factors.

Seasonal morphotypes of Drosophila suzukii differ in key life‐history traits during and after a prolonged period of cold exposure

open access: yesEcology and Evolution, 2020
Seasonal polyphenism in Drosophila suzukii manifests itself in two discrete adult morphotypes, the “winter morph” (WM) and the “summer morph” (SM). These morphotypes are known to differ in thermal stress tolerance, and they co‐occur during parts of the ...

Overwintering sites of Chrysophtharta bimaculata (Olivier) (Coleoptera: Chrysomelidae) in commercially managed Eucalyptus obliqua forests

open access: yes, 1998
Chrysophtharta bimaculata is a serious pest of eucalypt forests in Tasmania. The beetle overwinters as a diapausing adult, but it is poorly documented whether it forms overwintering aggregations or where it shelters.

Post-Epidemic Distribution of Schmallenberg Virus in Culicoides Arbovirus Vectors in Poland

open access: yesViruses, 2019
Pooled samples of female and male Culicoides midges (5146 and 332 pools, respectively) that corresponded to a total number of 124,957 specimens were collected between 2013–2017 in the vicinity of cattle barns that were distributed throughout Poland

The overwintering and abundance of cereal aphids

open access: yesAnnals of Applied Biology, 1974
SUMMARYThe longevity of Sitobion avenae varied inversely with temperature from 25 to over 100 days when reared outdoors on barley under lantern jars, being longest between December and April–May. This was due mainly to changes in the length of the pre‐ and post‐reproductive periods rather than the length of the period of reproduction.

Effects of pre-overwintering conditions on eupyrene and apyrene spermatogenesis after overwintering in Polygonia c-aureum (Lepidoptera: Nymphalidae) [PDF]

open access: yes, 2017
Sperm polymorphism is widely known in invertebrates. In insects, Lepidoptera has two types of sperm: nucleated eupyrene (fertile) sperm and anucleated apyrene (unfertile) sperm.

Distracted by a plant: movement of two invasive pentatomids, Halyomorpha halys and Nezara viridula, between companion plants and berry crops

open access: yesPest Management Science, EarlyView.
Adult Halyomorpha halys and Nezara viridula rapidly moved between berry crops and companion plants. Habitat use varied across environmental contexts, demonstrating that companion plantings function as dynamic elements in diversified cropping systems. Abstract BACKGROUND The brown marmorated stink bug Halyomorpha halys and the southern green stink bug ...

Population dynamics of Coccinella septempunctata (Coleoptera: Coccinellidae) in the region of Edremit Gulf in West Anatolia (Mount Ida)

open access: yesEuropean Journal of Entomology, 2018
This study reports seasonal presence of Coccinella septempunctata L. (Coleoptera: Coccinellidae) in Southeast Turkey, in 2008, 2009 and 2010. Samples were collected from crops in agricultural areas at altitudes of 10 m, 800 m and 1400 m from stands of ...
