A role of epigenetic mechanisms in regulating female reproductive responses to temperature in a pest beetle

open access: yesInsect Molecular Biology, Volume 33, Issue 5, Page 516-533, October 2024.
Temperature‐dependent, epigenetic impacts on life history components, after treatment with putatively epimutating drugs (3‐aminobenzamide [3AB] hypermethylating, and Zeb hypomethylating). Upward arrows depict increased fitness of treated females, whereas downward arrows depict fitness costs of treatment, relative to fitness of water‐treated controls ...

Fifty years of monitoring changes in the abundance of invertebrates in the cereal ecosystem of the Sussex Downs, England

open access: yesInsect Conservation and Diversity, Volume 17, Issue 5, Page 758-787, September 2024.
Monitoring invertebrates in cereal fields in southern England over 50 years (1970–2019) showed an overall decline in abundance. For taxa at the order/family level, 47% declined in abundance, 16% increased and 37% showed no change. Most functional groups declined, expect for pollinators—whose abundance did not change overall.

Exploring the contribution of the salivary gland and midgut to digestion in the swede midge (Contarinia nasturtii) through a genomics‐guided approach

open access: yesArchives of Insect Biochemistry and Physiology, Volume 116, Issue 3, July 2024.
The larvae of the swede midge, Contarinia nasturtii (Kieffer) (Diptera: Cecidomyiidae), feed on the meristem of brassica crops, resulting in galls that disrupt seed and vegetable production. The salivary gland and midgut transcriptomes of third instar larvae were examined, providing evidence for cooperative extra‐oral and gastrointestinal digestion ...

REVISION OF THE AUSTRALIAN TROPIDOCEPHALINI (HEMIPTERA: DELPHACIDAE: DELPHACINAE) [PDF]

open access: yesAustralian Journal of Entomology, 1991
AbstractAustralia has 2 genera and 4 species of Tropidocephalini: Pseudembolophora macleayi Muir, Tropidocephala dryas Kirkaldy, T. eximia (Kirkaldy) and T. neoamboinensis Muir; all are redescribed. T. hamadryas Kirkaldy is synonymised with T. dryas. A key to these genera and species is given.

Identification and functional analysis of the female determiner gene in the bean bug, Riptortus pedestris

open access: yesPest Management Science, Volume 80, Issue 3, Page 1240-1248, March 2024.
The gene Rpfmd, which determines female sex in Riptortus pedestris, was first identified. This gene is essential for the development of female‐specific characteristics during the embryonic, nymphal, and adult stages, but it has no effect on males. The Rpfmd gene is an ideal candidate for homing‐based gene driver genetic control.

Biology and population dynamics of the potential sugarcane Fiji disease vector Perkinsiella saccharicida (Homoptera: Delphacidae) in Réunion: evidence of its loss of biotic potential [PDF]

open access: yes, 2010
There is a risk that irrigation schemes that have been developed to enhance sugarcane, Saccharum spp, cropping on the island of Réunion could markedly broaden the distribution range in which outbreaks of the insect Persinkiella saccharicida Kirkaldy ...

Ecological and evolutionary consequences of temporal variation in dispersal

open access: yesEcography, Volume 2024, Issue 2, February 2024.
The importance of dispersal rates and distances has long been appreciated by ecologists and evolutionary biologists. An emerging field of research is revealing how temporal variation in dispersal can substantially influence ecological and evolutionary outcomes.
