, 2011
Very little is known about the incidence of egg parasitoids in odonates, perhaps because Odonata eggs are well protected in stems or leaves, sometimes below water.

Antennal chemoreceptors in the European ectoparasitoid Sclerodermus cereicollis (Hymenoptera: Bethylidae)

Microscopy Research and Technique, Volume 87, Issue 10, Page 2275-2291, October 2024.
An evident sexual dimorphism concerning antennae length, types, number, and distribution of chemosensilla is shown. Long sensilla basiconica are present in females and could play a role in the host location and/or maternal care. Multiporous sensilla chaetica, longer and mostly represented in males, could play a role in intraspecific relationships ...

A benefit–risk analysis for biological control introductions based on the protection of native biodiversity

Ecological Applications, Volume 34, Issue 6, September 2024.
Abstract The release of biological control agents has been an important means of controlling invasive species for over 150 years. While these releases have led to the sustainable control of over 250 invasive pest and weed species worldwide, a minority have caused environmental harm.

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

Insect 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.
