Nestmate Recognition in Social Insects: What Does It Mean to Be Chemically Insignificant?

Frontiers in Ecology and Evolution, 2020
Social insects use the blend of hydrocarbons present on their cuticle to efficiently distinguish nestmates from aliens. Intruders must therefore find a strategy to break the recognition code in order to exploit the colony resources. Twenty years ago, the

WASP-52b, WASP-58b, WASP-59b, and WASP-60b: Four new transiting close-in giant planets [PDF]

Astronomy & Astrophysics, 2013
We present the discovery of four new transiting hot jupiters, detected mainly from SuperWASP-North and SOPHIE observations. These new planets, WASP-52b, WASP-58b, WASP-59b, and WASP-60b, have orbital periods ranging from 1.7 to 7.9 days, masses between 0.46 and 0.94 M_Jup, and radii between 0.73 and 1.49 R_Jup.

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).

Climate change impact on Neotropical social wasps [PDF]

, 2011
Establishing a direct link between climate change and fluctuations in animal populations through long-term monitoring is difficult given the paucity of baseline data.

Anti-aphrodisiac compounds of male butterflies increase the risk of egg parasitoid attack by inducing plant synomone production [PDF]

, 2009
During mating in many butterfly species, males transfer spermatophores that contain anti-aphrodisiacs to females that repel conspecific males. For example, males of the large cabbage white, Pieris brassicae (Lepidoptera: Pieridae), transfer the anti ...

Post-embryonic Development in Brazilian Social Wasps

, 2020
This chapter presents a review of morphological studies of the immature stages of social Brazilian wasps, discussing aspects such as oviposition; instar larva, pre-pupa, and pupal stages; as well as duration times of the immature stages.

Differential Gene Expression and Protein Abundance Evince Ontogenetic Bias toward Castes in a Primitively Eusocial Wasp [PDF]

, 2010
Polistes paper wasps are models for understanding conditions that may have characterized the origin of worker and queen castes and, therefore, the origin of paper wasp sociality.

Host-natural enemy communities in a changing world: The impact of forest loss on cavity-nesting Hymenoptera and their natural enemies [PDF]

Brazilian Journal of Biology
Cavity-nesting bees and wasps provide important ecosystem services for humans. This study aimed to understand how the replacement of forests with non-forest habitats affects the structure and interaction network of cavity-nesting bees, wasps, and their ...

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

, 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 ...
