Taxonomy of the Crematogaster degeeri-species-assemblage in the Malagasy region (Hymenoptera: Formicidae) [PDF]

open access: yes, 2013
We revise the species-level taxonomy of the Crematogaster (Crematogaster) degeerispecies-assemblage, a group of related ants occuring in Madagascar and the wider Malagasy region, and further provide an identification key to all species-groups of the ...

Soybean plant architecture influences the capacity of Telenomus podisi to parasitize Euschistus heros eggs: implications for field releases

open access: yesPest Management Science, EarlyView.
Increasing soybean plant architectural complexity reduces the ability of Telenomus podisi to parasitize Euschistus heros eggs, highlighting the need to adjust parasitoid release rates in the field according to plant complexity (arrow direction and thickness correspond to the increasing strength of the variable) . Abstract BACKGROUND Plant architectural

Improved impact from the use of beneficial natural enemy species in Australian canola systems: challenges and required tools

open access: yesPest Management Science, EarlyView.
In canola production systems in Australia, practices for the use of beneficials (arthropod predators and parasitoids) as part of an Integrated Pest Management (IPM) strategy, have not been widely adopted. We outline how canola growers and their advisors can be supported with incremental steps, from passive to active management, to help shift them from ...

Slit in a Nest Site Influences the Nest Site Selection in Cavity Nesting Ant Colonies

open access: yesInsects
For ants, nests provide a refuge against predators and protection from environmental factors. Thus, choosing a good nest site is important for an ant colony, but nest sites are limited resources. Ants of the genus Temnothorax inhabit small cavities in, e.

Spiders in a hostile world (Arachnoidea, Araneae) [PDF]

open access: yes, 2011
Spiders are powerful predators, but the threats confronting them are numerous. A survey is presented of the many different arthropods which waylay spiders in various ways. Some food-specialists among spiders feed exclusively on spiders.

Effects of timed LED regimes on tomato plant traits, performance of two‐spotted spider mites, and predatory mites (Phytoseiulus persimilis)

open access: yesPest Management Science, Volume 81, Issue 4, Page 2300-2311, April 2025.
Light‐emitting diode (LED)‐based treatments for enhancing crop production and pest management have primarily focused on continuous treatments. This study, using Tetranychus urticae and Phytoseiulus persimilis, demonstrates that the timing of LED supplementation is crucial for designing integrated pest management strategies that improve both plant ...

Go High or Go Low? Adaptive Evolution of High and Low Relatedness Societies in Social Hymenoptera

open access: yesFrontiers in Ecology and Evolution, 2017
Cooperative groups can increase fitness either by helping kin or interacting with unlike individuals to produce social heterosis. They cannot, however, simultaneously maximize both benefits.
