Still on the same page: A gender comparison of the top 100 picture books from the UK and China published 2011–2020

Children &Society, EarlyView., 2023
Abstract As a primary source for the early ages, picture books guide preschool children's gender perception through stories and illustrations. However, previous studies have criticised an overall gender inequality in children's picture books. Compared to the increasing attention on gender diversity in the UK picture book industry, there has been little

Stage specific consumption and utilization of aphids, conspecific and heterospecific eggs by two species of Coccinella (Coleoptera: Coccinellidae)

European Journal of Entomology, 2014
The nutritive quality of aphids, conspecific and heterospecific eggs as food for ladybirds is a controversial issue. If ladybirds find aphids more palatable than eggs then they are more likely to efficiently exploit and be biocontrol agents of aphids. If

Temporal and climatic variation in the colour forms of Adalia bipunctata and Harmonia axyridis (Coleoptera: Coccinellidae) populations in the United Kingdom

European Journal of Entomology, 2022
Colour form polymorphism in Adalia bipunctata (Linnaeus, 1785) and Harmonia axyridis (Pallas, 1773) has been extensively studied in the past. Climate, season, and region are known to influence the colour form frequencies of these species, however, this ...

First report of nematodes Parasitylenchus bifurcatus Poinar & Steenberg, 2012 parasitizing multicolored Asian lady beetle Harmonia axyridis (Pallas, 1773) in Slovenia

Acta Agriculturae Slovenica, 2017
In years 2015 and 2016 around 200 specimens of ladybird species Harmonia axyridis were collected in Slovenia. Ladybirds were dissected and checked under stereomicroscope for presence of nematodes.

Ladybird communities in rural woodlands: Does an invader dominate?

Frontiers in Conservation Science, 2022
The invasive alien species Harmonia axyridis (Coleoptera: Coccinellidae) was first observed in the UK in 2004. Previous studies have demonstrated the adverse effects on other species of H. axyridis during its early stages of establishment.

Defence, oviposition and sex: semiochemical parsimony in two species of ladybird beetles (Coleoptera, Coccinellidae)? A short review.

European Journal of Entomology, 2000
Certain alkanes or their mixture present on the surface of ladybird elytra is important in the recognition of potential mates. Similar chemicals are present in the tracks of larvae, which deter conspecific female ladybirds from laying eggs in aphid ...

Diet and chemical defence in ladybird beetles (Coleoptera: Coccinellidae)

European Journal of Entomology, 2022
In this paper, I review the effects of the diet of ladybirds on chemical defence in this group of beetles. The tendency to reflex bleed and the diversity of autogenously produced alkaloids in different taxa may be evolutionarily related to diet and the ...

Rigorous Morphological Studies Confirm That the Classical Object of Pest Control Chilocorus kuwanae Is the Same Species as Ch. renipustulatus (Coleoptera: Coccinellidae)

Insects, 2020
The ladybug Chilocorus kuwanae, which was described in Japan, has been used for biological control of pests for 100 years. Chilocorus kuwanae was recently synonymized with Ch. renipustulatus described in Europe.
