Male behavior of Mischocyttarus cerberus (Hymenoptera, Vespidae) during attacks on the nest by ants
(2006-09-26)
The objectives of the present study were to verify if the males of the wasp Mischocyttarus cerberus participate in defense of the nest as they react to attack by ants, and to observe if they use chemical defense. First, ...

Characteristics of hydroxamic acid induction in wheat triggered by aphid infestation
(Springer New York LLC, 1997)
Hydroxamic acids (Hx) are natural products of Gramineae that are associated with cereal resistance to pests. We aimed at characterizing the induction of Hx accumulation in seedlings of wheat. Triticum aestivum, by short-term ...
Proteomic-components provide insights into the defensive secretion in termite workers of the soldierless genus Ruptitermes
(2020-02-20)
Termite soldiers constitute the defensive frontline of the colonies, despite workers also perform such tasks, especially within the Neotropical Apicotermitinae, in which all species are soldierless. Workers of the genus ...
Methyl Jasmonate Increases the Tropane Alkaloid Scopolamine and Reduces Natural Herbivory in Brugmansia suaveolens: Is Scopolamine Responsible for Plant Resistance?

Activation of early defense signals in seedlings of nicotiana benthamiana treated with chitin nanoparticles
(MDPI, 2020)
Chitin is an excellent material for the synthesis of nanoparticles because it is an elicitor and can form nanostructured materials. The application of chitin nanoparticles (CNPs) in plants can activate early defense responses ...
Dietary zinc deficiency predisposes mice to the development of preneoplastic lesions in chemically-induced hepatocarcinogenesis
(2016-10-01)
Although there is a concomitance of zinc deficiency and high incidence/mortality for hepatocellular carcinoma in certain human populations, there are no experimental studies investigating the modifying effects of zinc on ...
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 ...
