Evolution of Peripheral Visual System in the Apoidea: A Role for Food Item Mobility? [PDF]

Ecol Evol
Since larger compound eyes and ocelli altogether improve vision, one may expect that insects specialised in chasing very mobile resources possess such morphological optimisation. By analysing 77 species of bees and wasps, we have found that wasps had larger eyes, but not larger ocelli, than bees.

Contactless Acoustic Trapping of Hoverflies for Behavioral Studies. [PDF]

Ann N Y Acad Sci
We present a contactless tethering device based on acoustic levitation. Opposing ultrasonic transducers generate standing waves, creating stable pressure nodes that enable the sustained levitation of hoverflies (Episyrphus balteatus). We show that acoustic levitation does not appear to affect hoverfly behavior.

Multi-method approach to assessing the floral-visiting insect assemblage of rare, abophilous plant Baccharis vanessae in Southern California. [PDF]

Ecol Evol
In this study, we compare the accuracy of two different methods of monitoring to assess the insect assemblage of Encinitas Baccharis (Baccharis vanessae): focal observations and video recordings from camera traps. The insect vectors identified were as expected given B. vanessae pollination syndrome.

Seed Production and Pollinator Dependence in Native Wildflowers: Guiding Species Selection for Conservation Plantings. [PDF]

Ecol Evol
We investigated the pollination biology of eight native wildflower species in the southeastern U.S. to assess their dependence on insect pollinators and potential for self‐pollination. Most species showed significantly higher seed production and weight when open‐pollinated, indicating strong pollinator dependence, though some could reproduce without ...

Pathways for accidental biocontrol: The human-mediated dispersal of insect predators and parasitoids. [PDF]

Ecol Appl
Abstract Introductions of insect predators and parasitoids for biological control are a key method for pest management. Yet in recent decades, biological control has become more strictly regulated and less frequent. Conversely, the rate of unintentional insect introductions through human activities is rising.

The urban island: climatic suitability of Linepithema humile (Hymenoptera: Formicidae) and the role of cities in the invasion of the Western Palearctic. [PDF]

Integr Zool
Urban environments provide favorable conditions for the introduction and spread of nonnative and invasive species like the Argentine ant, which exploit ecological and climatic homogenization in cities to overcome natural barriers. Monitoring the expansion of such species can be achieved through potential distribution models, which in this study ...
