Arthropod Natural Enemies 2: Survival, Reproduction and Enhancement (ACTA JUTLANDICA) (v. 2)

This work includes contents: the influence of environmental factors and food on life cycle, ageing and survival of some carabid beetles; survival and reproduction in relation to habitat quality and food availability for Pterostichus oblongopunctatus; and can pitfall trap catches inform us about survival and mortality factors? It also contains: an analysis of pitfall trap data for Pterostichus cupreus (Coleoptera: Carabidae) in relation to crop rotation and crop specific husbandry practices; estimating the mortality rate of eggs and first free-living instar Lepthyphantes tenuis (Araneae: Linypiidae) from measurements of reproduction and development; assessment of survival and mortality factors in field populations of beneficial arthropods; reproduction and survival of linyphiid spiders, with special reference to Leptyphantes tenuis (Blackwell); the foraging efficiency of the parasitoid Diaeretiella rapae (Hymeoptera: Braconidae) in relation to the spatial distribution of aphids on plants; and indicators of prey quality for arthropod predators. It also contains: reproduction of beneficial predators and parasitoids in agroecosystems in relation to habitat quality and food Overwintering, oviposition and population dynamics of hoverflies (Diptera: Syrphidae) in Northern Germany in relation to small and large-scale landscape structure; phacelia tanacetifolia flower strips: their effect on beneficial invertebrates and gamebird chick food in an integrated farming system; management of arable crops and its effects on rove-beetles (Coleoptera: Staphylinidae), with special reference to the effects of insecticide treatments; and effects of reduced tillage systems in sugar beet on predatory and pest arthropods. It also contains topics such as: enhancement of non-target insects: indications about dimensions of unsprayed crop edges; comparison of the carabid fauna of a wheat field and its surrounding habitats; a review of the progress made to control the cabbage root fly (Delia radicum) using parasitoids; and can sustainable agricultural practices affect biodiversity in agricultural landscapes? It contains a case study concerning orchards in Italy; ground photo-eclector evaluation of the numbers of carabid beetles and spiders found in and around cereal fields is treated with either inorganic or compost fertilisers.
