Progressive Cellularization of Blastoderm and Extraembryonic Tissue Formation in the Ant Camponotus floridanus

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Illustration of the process of cellularization in Camponotus floridanus (top row) compared to Drosophila melanogaster (bottom row). Progressive direct formation of differentiating blastoderm mode is depicted using hexagons that represent energids (without borders) and cells (with borders). Colors of nuclei represent different cell types.

T(w)o Patch or Not T(w)o Patch: A Novel Biocontrol Model

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT A number of top‐down biocontrol models have been proposed where the introduced predators' efficacy is enhanced via the provision of additional food (AF). However, if the predator has a pest‐dependent monotone functional response, pest extinction is unattainable. In the current manuscript, we propose a model where a predator with pest‐dependent

Further contributions to the tritrophic plant-aphid-parasitoid associations in Malta with special reference to Aphis nerii (Hemiptera, Aphidoidea) as a prevalent refugium of Aphidiinae (Hymenoptera, Braconidae) [PDF]

, 2013
Four species of aphid parasitoids, namely Aphidius colemani, Binodoxys angelicae, Lysiphlebus fabarum and Lysiphlebus testaceipes were reared from Aphis nerii on Nerium oleander and/or Stephanotis floribunda in Malta.

Smelling the wood from the trees: non-linear parasitoid responses to volatile attractants produced by wild and cultivated cabbage [PDF]

, 2011
Despite a large number of studies on herbivore-induced plant volatiles (HIPVs), little is known about which specific compounds are used by natural enemies to locate prey- or host- infested plants.

Area‐restricted search under realistic constraints

Oikos, EarlyView.
Abstract Area‐restricted search (ARS) is one of the most influential and widely used concepts in foraging theory, capturing a simple rule by which animals intensify local search following a resource encounter. Because ARS performs well in many spatially structured environments, it serves as a basic model for interpreting movement patterns across taxa ...

Do age and mating status affect olfactory response of the parasitoid, Microplitis croceipes (Hymenoptera: Braconidae) to host-related plant odors? [version 2; referees: 2 approved]

F1000Research, 2018
Background: Parasitic wasps (parasitoids) use volatile organic compounds released by herbivore-infested plants to locate their hosts. Response of parasitoids to plant odors may be plastic and dependent on their physiological state.

The shared benefits of fallen fruits: A novel mechanism stabilizing a nursery pollination mutualism between Sambucus and kateretid beetles

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how cooperative interactions remain stable matters for biodiversity because many plants rely on specialist insects that can also impose reproductive costs. We studied the interaction between Sambucus sieboldiana and seed‐consuming Heterhelus beetles through detailed field observations and pollination experiments.

Differing success of defense strategies in two parasitoid wasps in protecting their pupae against a secondary hyperparasitoid

, 2011
During their larval development, endoparasitoids are known to dispose of host resources in several different ways. Some parasitoid wasps consume most or all tissues of the host, whereas others consume a small fraction of host resources and either ensure ...

SYN‐A, a naturally derived synergist, restores pyrethroid efficacy against cabbage stem flea beetle but negatively impacts its parasitoid Microctonus brassicae

Pest Management Science, EarlyView.
SYN‐A, a naturally derived synergist, inhibited key metabolic pathways associated with pyrethroid insecticide resistance in cabbage stem flea beetle (CSFB) and its parasitoid Microctonus brassicae. SYN‐A restored pyrethroid efficacy against resistant CSFB allowing up to 80% reduction in application rates.
