Comparative analysis of Calanus finmarchicus demography at locations around the Northeast Atlantic [PDF]

, 2000
Standardized time-series sampling was carried out throughout 1997 at seven locations around the Northeast Atlantic to investigate regional variations in the seasonal demography of Calanus finmarchicus.

Water availability and land‐use shape the diversity of Odonata in the Middle East

Insect Conservation and Diversity, EarlyView.
Odonata diversity in the Middle East depends on the availability of long‐lasting waters, emphasizing the importance of preserving stable aquatic habitats for biodiversity conservation under climate change‐driven droughts. Agricultural expansion is associated with increased Odonata species richness, but overall trait diversity remains limited ...

Lab observations on prolonged chrysalis diapause of Brahmaea (Acanthobrahmaea) europaea Hartig (Lepidoptera: Brahmaeidae)

Fragmenta Entomologica, 2018
Brahmaea (Acanthobrahmaea) europaea Hartig, 1963, is an Italian endemic species exhibiting a very restricted geographic distribution (Basilicata and Campania regions, Grotticelle di Monticchio Nature Reserve and neighbouring areas), and developing as larvae on a few Oleaceae (Fraxinus angustifolia subsp.

Prolonged diapause in the ectoparasite Carnus hemapterus (Diptera: Cyclorrhapha, Acalyptratae) – how frequent is it in parasites?

Parasitology, 2006
Prolonged diapause is usually interpreted as an adaptation to unpredictable environmental conditions and resource availability. Many parasites usually face highly unpredictable environments, therefore prolonged diapause should be common among these organisms.

Conservation implications of shifting habitat use in migrating insects: Selection patterns in a threatened damselfly show that season‐specific actions are needed

Insect Conservation and Diversity, EarlyView.
Well‐preserved heathlands of NW Italy are the main overwintering habitat of Sympecma paedisca, while grassy margins in farmland are used only in summer and are avoided from autumn onwards. Grassy margins in farmland act as corridors during the species' migrations between its breeding (ricefields) and overwintering (lowland heathlands) grounds ...

A protracted phenology: Post‐diapause larval development of a threatened butterfly

Insect Conservation and Diversity, EarlyView.
Larval survival during diapause was high; hibernaculum webs were mostly located near Succisa pratensis plants, which often retained vital leaves through winter. Post‐diapause developmental time varied strongly depending on exposure to different microclimates, being reduced by litter cover, solar radiation and a higher heat load index.

Comparison of Reproductive and Flight Capacity of Loxostege sticticalis (Lepidoptera: Pyralidae), Developing From Diapause and Non-Diapause Larvae [PDF]

, 2012
The beet webworm, Loxostege sticticalis (L.) (Lepidoptera: Pyralidae), uses both diapause and migration as life history strategies. To determine the role of diapause plays in the population dynamics of L.

The Ecological Factors Associated With the Survival, Establishment, and Movement of Aedes aegypti and Ae. albopictus: A Scoping Review

Journal of Applied Entomology, EarlyView.
ABSTRACT Aedes aegypti and Ae. albopictus are mosquito species of public health significance and collectively responsible for the transmission of several arboviruses. Ongoing climatic changes are anticipated to have impacts on their survival, establishment, and movement.

Regulation of the development of flight muscles in long-winged adults of the flightless bug Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae)

European Journal of Entomology, 2008
We studied the development of the indirect flight muscles and reproductive organs in long-winged (macropterous) adults of the flightless bug Pyrrhocoris apterus (L.) and the factors involved in flight muscles histolysis by means of total protein analysis.

Population management of cone and seed insects in spruce seed orchards [PDF]

, 2011
Seed orchards have been established in order to produce high quality seeds for reforestation and forestation. However, seed production in spruce (Picea abies (L.) Karst.) seed orchards is severely hampered by cone- and seed-feeding insects.
