Chemical communication in Apis mellifera: Temporal modulation of alarm behaviors
(1996-01-01)
The effect of pheromones and their chemical analogues in honeybee alarm behaviors was studied in observation boxes. Defensive behaviors, as follows: a) attraction to scent source, b) elevation of wings in 'V', c) abdomen ...
Not all toxic butterflies are toxic: high intra- and interspecific variation in sequestration in subtropical swallowtails
(Ecological Society of America, 2017-12-11)
Many herbivorous insects make use of plant secondary metabolites by consuming and storing these toxic compounds in their body tissue or integument, thereby obtaining chemical defense against their natural enemies. Swallowtail ...
First Biosynthetic pathway of 1-hepten-3-one in Iporangaia pustulosa (Opiliones)
(Nature Publishing GroupLondonInglaterra, 2013)
Which variables influence the herbivory amount on Montrichardia spp. (Araceae) in aquatic ecosystems?
(Universidad de Costa Rica, 2022)
Behavioral analysis of the interaction between the spitting spider Scytodes globula (Araneae: Scytodidae) and the harvestman Discocyrtus invalidus (Opiliones: Gonyleptidae)
(American Arachnological SocietyCollege Park, 2012)
Spitting spiders (Scytodidae) have a distinct predatory strategy in which they eject a sticky secretion from their cheliceral fangs to immobilize prey. This behavior could potentially allow the spider not only to avoid ...
Harvest-ironman: heavy armature, and not its defensive secretions, protects a harvestman against a spider
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2011)
Natural selection has caused prey species to evolve distinct defensive mechanisms. One of such mechanisms was the evolution of noxious or distasteful chemicals, which have appeared independently in a number of vertebrates ...
Solar UV-B radiation modulates chemical defenses against Anticarsia gemmatalis larvae in leaves of field-grown soybean
(Pergamon-Elsevier Science Ltd, 2017-09)
Although it is well known that solar ultraviolet B (UV-B) radiation enhances plant defenses, there is less knowledge about traits that define insect resistance in field-grown soybean. Here we study the effects of solar ...
Dietary alkaloid sequestration in a poison frog: an experimental test of alkaloid uptake in Melanophryniscus stelzneri (Bufonidae)
(SpringerNew York, 2013-12)
Several lineages of brightly colored anurans independently evolved the ability to secrete alkaloid-containing defensive chemicals from granular glands in the skin. These species, collectively referred to as ‘poison frogs,’ ...
