Two altemative strategies for spider egg parasitoids

, 2017
Regulation of intensity of parasitism in spider-egg parasitoids is more complex than in mast parasites, since spider eggs are tightly packed in sacs and factors controlling proportion of eggs parasitized per sac also regulate population densities. Both microhymenopterans Baeus achaearaneus (Scelionidae) and Tetrastichus sp.

Rainfall shapes the physiological condition, but not the body size, of an introduced dung beetle in Brazilian pastures

Ecological Entomology, Volume 51, Issue 2, Page 346-355, April 2026.
Understanding rainfall‐driven physiological shifts in dung beetles is crucial to predict how climate change may affect the fitness and persistence of key insect species in tropical pastures. We compared body size, dry, lipid and muscle masses of Digitonthophagus gazella collected during dry and rainy seasons in Brazilian pastures to assess the effects ...

The genome and stage‐specific transcriptomes of the carrot weevil, Listronotus oregonensis, reveal adaptive mechanisms for host specialisation and symbiotic interactions

Insect Molecular Biology, Volume 35, Issue 2, Page 126-138, April 2026.
Comprehensive genome and stage‐specific transcriptomes reveal 14,637 genes in Listronotus oregonensis, advancing genetic insights into a key agricultural pest. Compared with related species, L. oregonensis exhibits reduced chemoreceptor gene families but expanded detoxification gene clusters, reflecting its narrow host range and adaptability.

Kinship Analysis Confirms Tolerant Galapagos Mockingbirds Are a Source of Nest Flies That Threaten Darwin's Finches

Molecular Ecology, Volume 35, Issue 7, April 2026.
ABSTRACT Host species have evolved different strategies for dealing with parasites. ‘Vulnerable’ hosts, which suffer reduced fitness from parasites, are under selection to evolve defences. ‘Tolerant’ hosts, by contrast, avoid reductions in fitness by mitigating parasite damage.
