Frost Decreases Fruit Production in a Neotropical Savanna: Implications for Frugivorous Bird Abundances

open access: yesBiotropica, Volume 58, Issue 3, May 2026.
Severe frost events seem to be happening on average every 5 years, rather than 7 years, as previously reported in the southern limit of the Cerrado, a Neotropical savanna.

Chrysoperla externa (Neuroptera: Chrysopidae) as a Potential Biological Control Agent of Raoiella indica (Acari: Tenuipalpidae)

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 4, Page 335-342, April 2026.
First and third instar Chrysoperla externa showed efficient predatory capacity at low R. indica density, but second instar C. externa exhibits a density‐dependent predatory ability. The lacewing C. externa shows promise as a biocontrol agent for R. indica in coconut because it consumed 8362 R. indica females across all its larval instars.
