Insecticides outweigh rye cover crop in triggering secondary pest outbreaks

open access: yesPest Management Science, Volume 81, Issue 12, Page 7971-7984, December 2025.
Insecticides outweigh rye cover crop in triggering secondary pest outbreaks. Zeus Mateos‐Fierro*, Ashley Leach, Ian Kaplan. Spider mite and melon aphid outbreaks are enhanced with broad‐spectrum insecticides, while natural enemies are reduced. However, rye cover crop has little effect on either pest or natural enemy populations.

Bumble Bees and Honey Bees on Islands Harbour Reduced Viral Species Richness, Yet Honey Bee Populations Are Dominated by a Deformed Wing Virus Recombinant

open access: yesMolecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT Pollinators harbour diverse RNA viromes that play a vital role in their health. Yet, factors that shape viral communities are often unclear. The European honey bee (Apis mellifera) is experiencing a viral epidemic since the emergence of the parasitic mite Varroa destructor (varroa) introduced vector‐borne transmission, which has also been ...

Χωροταξική κατανομή του Aphis gossypii στο βαμβάκι

open access: yesENTOMOLOGIA HELLENICA, 1998
The spatial distribution of Aphis gossypii (Glover) on cotton was studied by using Taylor’s power law, the negative binomial parameter k and the iδ-index of aggregation. Both k and iδ were related to density with curvilinear relationships and indicated that aggregation decreases as density increases up to densities of, approximately, two individuals ...
