Geographical Range and Laboratory Studies on Apanteles opuntiarum (Hymenoptera: Braconidae) in Argentina, a Candidate for Biological Control of Cactoblastis cactorum (Lepidoptera: Pyralidae) in North America [PDF]

open access: yes, 2014
La polilla de la tuna, Cactoblastis cactorum (Berg) (Lepidoptera: Pyralidae), es una plaga que amenaza las Opuntia spp. nativas de América del Norte. Se han implementado varias estrategias para su control, erradicándola de México pero no de los Estados ...

The Intracellular Bacterium Wolbachia Uses Parasitoid Wasps as Phoretic Vectors for Efficient Horizontal Transmission

open access: yesPLoS Pathogens, 2015
Facultative bacterial endosymbionts are associated with many arthropods and are primarily transmitted vertically from mother to offspring. However, phylogenetic affiliations suggest that horizontal transmission must also occur.

Embryogenesis in Myrmicine Ants Combines Features of Short Germ‐Band Development With a Progressive Mode of Segmentation

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Different insect species exhibit remarkable diversity in the developmental trajectories from fertilized eggs to hatching larvae. For three myrmicine ant species, we observe a novel combination of a developmental features: small embryonic primordia, a mode of embryogenesis termed short/intermediate germ‐band development, and progressive establishment of

The puzzle of sub-maximal resource use by a parasitoid wasp [PDF]

open access: yesAmerican Naturalist, Volume 185, Number 4, April 2015, 2014
When there is conspicuous under-exploitation of a limited resource, it is worth asking what mechanisms allow presumably valuable resources to be left unused? Evolutionary biologists have generated a wide range of hypotheses to explain this, ranging from interdemic group selection to selfishly prudent individual restraint.

Eco control of agro pests using imaging, modelling & natural predators [PDF]

open access: yes, 2014
Caterpillars in their various forms: size, shape, and colour cause significant harm to crops and humans. This paper offers a solution for the detection and control of caterpillars through the use of a sustainable pest control system that does not require

Host and Habitat Use by Parasitoids (Hymenoptera: Pteromalidae) of House Fly and Stable Fly (Diptera: Muscidae) Pupae [PDF]

open access: yes, 2018
House fly and stable fly pupae were collected during the summer from a dairy farm in northern Illinois. Spalangia nigroaenea accounted for most of the parasitoids recovered from house flies. Spalangia nigra, S.

Concurrent DNA meta‐barcoding and plankton imaging reveal novel parasitic infection and competition in a diatom

open access: yesLimnology and Oceanography, EarlyView.
Abstract Little is known about diatom parasitism in marine systems. Guinardia delicatula, a biomass‐dominant diatom on the Northeast US Shelf (NES), is regularly parasitized by the protistan nanoflagellate, Cryothecomonas aestivalis in this region. While G.

Bacterial endosymbionts protect aphids in the field and alter parasitoid community composition.

open access: yesEcology, 2016
It has become increasingly evident that many organisms rely on microbial symbionts for defense against natural enemies, but the ecological importance of defensive symbionts for natural communities still needs to be investigated.

Multitrophic interactions: How plant defense is amplified by entomopathogenic nematode‐infected cadavers

open access: yesNew Plant Protection, EarlyView.
Entomopathogenic nematode‐infected cadavers trigger plants to release volatile organic compounds that deter herbivores, attract parasitic wasps, and boost defense responses, highlighting their potential for sustainable pest management. Abstract Grasping the dynamics between plants and herbivores, as well as the defenses triggered by insects, may hold ...
