The costs and benefits of multiple mating in a mostly monandrous wasp [PDF]

, 2015
Funding: NERC DTGThe taxonomically widespread nature of polyandry remains a puzzle. Much of the empirical work regarding the costs and benefits of multiple mating to females has, for obvious reasons, relied on species that are already highly polyandrous.

Sublethal herbicide exposure alters cotton susceptibility to aphid infestation

Pest Management Science, EarlyView.
Sublethal herbicide exposure altered cotton susceptibility to aphids. Aphid severity was highest when applications occurred at early vegetative stages and declined as the crop matured. In glasshouse, herbicide effects were dose‐dependent. Abstract BACKGROUND Herbicides remain vital tools for weed control, yet their effects can extend beyond weeds to ...

Social Wasp-Flower Visiting Guild Interactions in Less Structurally Complex Habitats are More Susceptible to Local Extinction

Sociobiology, 2013
Several studies have shown that habitat complexity is an important factor for the dynamic and stability of interacting species. However, it is not known how the habitat complexity may affect the tolerance of wasp-flower interactions to local extinction ...

Castes and Polymorphisms in Neotropical Social Wasps

, 2020
Neotropical social wasps have a set of chimeric characteristics that make them unique and difficult to fit into current theories on the evolution of social behavior (Noll and Wenzel, Biol J Linn Soc 93: 509–22, 2008). Among them, the presence of more than one functional queen (polygyny), absence of strong morphological differentiation, and flexibility ...

Spin–orbit alignment for three transiting hot jupiters: WASP-103b, WASP-87b, and WASP-66b [PDF]

, 2016
We have measured the sky-projected spin–orbit alignments for three transiting hot Jupiters, WASP-103b, WASP-87b, and WASP-66b, using spectroscopic measurements of the Rossiter–McLaughlin effect, with the CYCLOPS2 optical fiber bundle system feeding the ...

Insect pests in Brassica napus crops: toward ecologically optimized integrated pest management

Pest Management Science, EarlyView.
Ecologically optimized IPM: Integrating landscape, biological, and chemical strategies for enhanced pest management. Key findings: Optimizing canola IPM requires the deliberate alignment of habitat diversification, behavioral conditioning, and evolutionary processes.

Mating history shapes Wolbachia‐induced cytoplasmic incompatibility and female fitness in an insect pest

Pest Management Science, EarlyView.
Mating order and remating of females by males with different endosymbiont associations strongly shape Wolbachia‐induced cytoplasmic incompatibility, female fitness and offspring sex ratio. An incompatible first mating was weakly affected if followed by a compatible mating and vice versa, indicating strong first‐male sperm precedence with consequences ...

WASP-South hot Jupiters: WASP-178b, WASP-184b, WASP-185b & WASP-192b [PDF]

, 2019
We report on four new transiting hot Jupiters discovered by the WASP-South survey. WASP-178b transits a V = 9.9, A1V star with Teff = 9350 ± 150 K, the second-hottest transit host known.

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

Pest 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 ...
