Subject:
Chrysoperla; biological control; chronic exposure; cryptic species; egg hatchability; egg production; longevity; mass rearing; oviposition; population dynamics; progeny; reproductive performance; sex ratio; Europe
Abstract:
... Chrysoperla agilis Henry et al. is one of the five cryptic species of the carnea group found in Europe. They are known to widely occur in agricultural fields and survive and reproduce in a wide range of temperatures. The reproductive biology of the cryptic species is poorly known, especially regarding the number of matings required for the females’ maximum reproductive output. We recorded the egg ...

Tetranychus; arthropods; colonizing ability; egg production; entomology; international trade; longevity; pests; prediction; resource allocation; Europe
Abstract:
... With significant surge of international trade in recent decades, increasingly more arthropod species have become established outside their natural range of distribution, causing enormous damage in their novel habitats. However, whether a species can colonize its new environment depends on its ability to overcome various barriers which may result in establishment failure, such as inbreeding depress ...

Abstract:
... Although conventional battery hen cages are still prevalent in the global market, the movement towards greener methods is gaining momentum beyond Europe. However, egg quality and the degree to which it is affected by the different systems of production remains a controversial subject and there is still no consensus among researchers. Using PRISMA guidelines the literature reporting the housing sys ...

... Keel bone damage (KBD) in laying hens is an important welfare problem in both conventional and organic egg production systems. We aimed to identify possible risk factors for KBD in organic hens by analysing cross-sectional data of 107 flocks assessed in eight European countries. Due to partly missing data, the final multiple regression model was based on data from 50 flocks. Keel bone damage inclu ...

Abstract:
... Spotted wing drosophila (SWD) has emerged as a major invasive insect pest of small berry fruits in the Americas and Europe since the late 2000s. Thus, phytosanitary treatment of commodities for export is imperative to prevent the movement of viable SWD to newer areas. In the present study, all developmental stages of SWD were irradiated with different doses of gamma and electron beam radiation to ...

Abstract:
... In Kuwait, poultry meat is popular and a major source of dietary protein. Despite the increase in local production, importation to Kuwait has increased, to cover the high local demand for poultry meat. Self-sufficiency has, however, reached 20% of the local demand for poultry meat. This is mainly due to the continuous rise in human population and an increased demand for poultry meat with an averag ...
