Ecology and evolution of pyrazines in insects
Biological Reviews, EarlyView.ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

European Journal of Entomology, 2019 For biological control it is necessary to store mass-reared biological control agents when the demand is low. The objective of this study is to increase their shelf life without significantly reducing their fitness. The ladybird Hippodamia variegata is a

Maintenance of polymorphism in the orb weaving spider species Agalenatea redii (Araneae, Araneidae) [PDF]
, 2012 The maintenance of polymorphism within populations may be the consequence of several elements of species life history such as use of space, activity rhythms, predation, parasitism and reproduction.

Area‐restricted search under realistic constraints
Oikos, EarlyView.Abstract Area‐restricted search (ARS) is one of the most influential and widely used concepts in foraging theory, capturing a simple rule by which animals intensify local search following a resource encounter. Because ARS performs well in many spatially structured environments, it serves as a basic model for interpreting movement patterns across taxa ...

European Journal of Entomology, 2000 The aim of this work was to determine the impact of allelochemicals (glucosinolates/isothiocyanates) from Brassicaceae (Brassica napus and Sinapis alba) at two trophic levels in relation to biological control efficacy. The impact of these plants on aphid

Patterns of contribution to citizen science biodiversity projects increase understanding of volunteers’ recording behaviour [PDF]
, 2016 The often opportunistic nature of biological recording via citizen science leads to taxonomic, spatial and temporal biases which add uncertainty to biodiversity estimates.

Pest Management Science, EarlyView.Rhizobacterial inoculation of barley reduced Sitobion avenae populations by inducing plant resistance and modifying volatiles that attracted parasitoid wasps earlier, enhancing both bottom‐up and top‐down pest control. Abstract BACKGROUND Soil rhizobacteria can enhance crop resistance to insect herbivores and influence higher trophic interactions ...

Effects of autumn kaolin, pyrethrin, and ladybird larvae (Adalia bipunctata) applications on the spring populations of the rosy apple aphid (Dysaphis plantaginea) in an experimental apple orchard (cv. Glockenapfel) [PDF]
, 2003 Effects of different strategies (insecticide treatment, physical barrier, biocontrol) to control autumn forms of Dysaphis plantaginea. Question 1: Efficacy of pyrethrum, kaolin, and larvae of A.

Pest Management Science, EarlyView.Starvation stress significantly affected the growth and development of Hippodamia variegata. Combined transcriptome and metabolome analysis and RNA interference verification revealed that HvarAKR1B1 may be involved in the response of Hippodamia variegata to starvation stress.
