Reproductive aspects of the Purple-throated Euphonia, Euphonia chlorotica (Aves: Fringillidae) in southeastern Brazil, and first record of the species nesting inside a vespiary

Zoologia (Curitiba), 2017
Despite the fact that E. chlorotica (Linnaeus, 1766) is common and widely distributed in South America, the reproductive aspects of the species are poorly documented. Here we present data on 18 active nests found from August to February, between 2007 and

Life History and the Transitions to Eusociality in the Hymenoptera

Frontiers in Ecology and Evolution, 2021
Although indirect selection through relatives (kin selection) can explain the evolution of effectively sterile offspring that act as helpers at the nest (eusociality) in the ants, bees, and stinging wasps (aculeate Hymenoptera), the genetic, ecological ...

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).

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 ...

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.

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.

Parasitoid wasps from three Jamaican localities: A pilot study [PDF]

, 2014
"Parasitoid wasps are an extremely speciose, ecologically and economically crucial group of insects. Despite this, they have received disproportionally little attention from scientists, in particular in certain areas of the world.

Sternal Exocrine Glands in Neotropical Social Wasps

, 2020
A great diversity of exocrine glands is found in social insects. The main social function of exocrine glands is the production of pheromones, which are related to the maintenance of social organization of the colony, as interactions of dominance ...

The foraging behaviour of neotropical social wasps

, 2021
The evolution of eusociality among the Hymenoptera is related to the development of colonies with big populations, which in turn presented these social insects with the need for a constant intake of nutrients necessary for their collective survival ...

Rhizobacteria regulate colonising Sitobion avenae aphid populations through induced host resistance and alter plant volatiles promoting early parasitoid recruitment on barley (Hordeum vulgare). [PDF]

Pest Manag Sci
Rhizobacterial inoculation of barley reduced Sitobion avenae populations by inducing plant resistance and modifying volatiles that attracted parasitoid wasps earlier, enhancing both bottom‐up and top‐down pest control. Abstract BACKGROUND Soil rhizobacteria can enhance crop resistance to insect herbivores and influence higher trophic interactions ...
