Interactions of Opuntia ficus-indica with Dactylopius coccus and D. opuntiae (Hemiptera: Dactylopiidae) through the Study of Their Volatile Compounds [PDF]
PlantsOpuntia ficus-indica has always interacted with many phytophagous insects; two of them are Dactylopius coccus and D. opuntiae. Fine cochineal (D. coccus) is produced to extract carminic acid, and D.

Hiding in plain sight: Cryptic enemies are found on cochineal (Hemiptera: Dactylopiidae), a scale insect of economic and cultural significance. [PDF]
Ecol Evol, 2022 We characterize two cryptic enemies of the community of the scale insect cochineal in Tucson, Arizona, USA in the Sonoran Desert. A typically all black undescribed Hyperaspis sp. shares a niche with Hyperaspis trifurcata. We also show that a micropterous ant‐mimic wasp is a semi‐gregarious primary parasitoid of cochineal, to our knowledge the first ...

Seed and Color Preferences of Wild Carrion Crows From Cafeteria Experiments. [PDF]
Ecol EvolIn the context of significant damage caused by corvids to spring crops, there is a need for sustainable management strategies informed by a better understanding of their ecology. Our study addresses this gap by focusing on the seed and color preferences of wild carrion crows.

Zootherapy as traditional therapeutic strategy in the Cholistan desert of Bahawalpur‐Pakistan
Veterinary Medicine and Science, Volume 9, Issue 4, Page 1861-1868, July 2023., 2023 Based on this communication we could recommend that this type of abandoned knowledge should be considered for the management and conservation of faunistic resources. However, the advantageous role of animals and their products was reported but more extensive research is required to explore the bioactive constituents in the raw material of these animals

Wild herbivores enhance resistance to invasion by exotic cacti in an African savanna
Journal of Ecology, Volume 111, Issue 1, Page 33-44, January 2023., 2023 Our experimental and observational findings that wild herbivores confer resistance to invasion by exotic cacti add to evidence that conserving and restoring native herbivore assemblages (particularly megaherbivores) can increase community resistance to plant invasions. Photo credit: Gustavo Lozada (same for potential cover image). Abstract Whether wild
