Courtship Is a Major Factor of Mating-Shortened Male Lifespan in an Egg Parasitoid. [PDF]

Ecol Evol
Mating is vital for population survival but often leads to reduced post‐mating longevity in both sexes. In many insects, sperm‐related factors are thought to cut male longevity, while in Anastatus disparis, mating also affects male longevity, with courtship being the main cause. Transcriptomic analyses of A.

Seasonal occurrence of brown marmorated stink bug and its impact in organic and conventional kiwifruit orchards in north-western China. [PDF]

Pest Manag Sci
Higher populations of brown marmorated stink bug (BMSB) and increased kiwifruit damage were recorded in organic orchards, BMSB population exhibiting a consistent pattern of two generations annually over 3 years. Feeding damage peaked at 59% and 60% in October 2019 and 2021, respectively, with no significant differences in overall damage rates between ...

Microhymenoptera in roadside verges and the potential of arthropod‐friendly mowing for their preservation

Journal of Applied Entomology, Volume 147, Issue 10, Page 1035-1044, December 2023., 2023
Abstract The worldwide decline of insects is one of the major challenges for humankind. One of its main drivers is intensive farming, which reduces habitats and food resources for insect populations and causes direct mortality by pesticides. In addition, mowing of grassland poses another threat to insects, especially when it is done frequently, such as

Parasitoids and pathogens in a collapsing Lymantria dispar (Lepidoptera: Erebidae) population in Lower Austria

Journal of Applied Entomology, Volume 147, Issue 8, Page 676-687, September 2023., 2023
Abstract A local population outbreak of the spongy moth, Lymantria dispar L. (Lepidoptera: Erebidae), in Lower Austria, resulted in the defoliation of an oak forest in 2018 and 2019. In the study year 2020, the population density was still high but was expected to decline.

Age‐dependent changes in reproductive allocation in a facultative ectoparasite, the blowfly Lucilia sericata (Meigen) (Calliphoridae)

Physiological Entomology, Volume 48, Issue 2-3, Page 68-74, September 2023., 2023
Resource allocation to reproduction was measured in the blowfly Lucilia sericata. Lipid in the ovary, declined with age. This decline was associated with the production of fewer and smaller eggs per batch. Abstract Organisms trade‐off limited resources between life‐history traits to maximize fitness.

The usefulness of chromosomes of parasitic wasps of the subfamily Eupelminae (Hymenoptera: Chalcidoidea: Eupelmidae) for subfamily systematics

European Journal of Entomology, 2008
Karyotypes of 16 Eupelminae species were analyzed. The haploid chromosome number was found to be much more diverse than the n = 5 previously recorded for three studied species.
