Tipos de asociación entre ácaros e Hymenópteros; 1: Sennertia (A.) splendidulae Alzuet y Abrahamovich, 1988 (Acarina: Chaetodactylidae) comensal y forético de Xylocopa (S.) Splendidula splendidula Lepeletier, 1841 (Hymenoptera: Anthophoridae)
(IICA, San José (Costa Rica), 1990-07)
Se analizan el grado y los tipos de relación detectados en ácaros Chaetodactilidae que viven asociados con Xylocopa splendidula splendidula. Estos estudios se realizan con base en el conocimiento sobre el comportamiento y ...
Symbionts do not affect the mating incompatibility between the Brazilian-1 and Peruvian morphotypes of the Anastrepha fraterculus cryptic species complex
(Springer Nature, 2019-12)
The South American fruit fly, Anastrepha fraterculus, is clearly undergoing a speciation process. Among others, two of their morphotypes, the Brazilian-1 and Peruvian, have accumulated differences in pre- and post-zygotic ...
Phosphatidylinositol 3-kinase function at very early symbiont perception: a local nodulation control under stress conditions?
(Society for Experimental Biology, 2018-04)
Root hair curling is an early and essential morphological change required for the success of the symbiotic interaction between legumes and rhizobia. At this stage rhizobia grow as an infection thread within root hairs and ...
Behavioural response of the woodwasp Sirex noctilio to volatile emissions of its fungal symbiont
(2015-01)
The wood-boring wasp, Sirex noctilio, is a global invasive pest that infects and kills pine trees by inoculating spores of a symbiotic fungus (Amylostereum areolatum) at oviposition. Wasp larvae depend on fungal growth to ...
Host selection by Ibalia leucospoides based on temporal variations of volatiles from the hosts’ fungal symbiont
(2016-12)
Insect parasitoids locate hosts via reliable and predictable cues such as volatile emissions from hosts and/or host plants. For insects that depend on mutualistic organisms, such as many wood-boring insects, symbiont-derived ...
Stable symbiotic nitrogen fixation under water-deficit field conditions by a stress-tolerant alfalfa microsymbiont and its complete genome sequence : Short communication
(2017-12)
We here characterized the stress-tolerant alfalfa microsymbiont Sinorhizobium meliloti B401. B401-treated plants showed high nitrogen fixation rates under humid and semiarid environments. The production of glycine betaine ...
Coxiella endosymbiont of rhipicephalus microplus modulates tick physiology with a major impact in blood feeding capacity
(Frontiers Media, 2022-05)
In the past decade, metagenomics studies exploring tick microbiota have revealed widespread interactions between bacteria and arthropods, including symbiotic interactions. Functional studies showed that obligate endosymbionts ...
First identification of bacterial endosymbionts in three South-American spittlebug pests: Notozulia entreriana, Deois mourei and Deois knoblauchii
(Alma Mater Studiorum, Università di Bologna, 2022-06)
Spittlebugs cause major pasture damage in the Neotropics. As most xylem-feeders, they depend on microbial symbionts to supply essential amino acids to their diet. Here, the obligate nutritional endosymbiont ‘Candidatus ...
Polyamines and Legumes: Joint Stories of Stress, Nitrogen Fixation and Environment
(Frontiers Media, 2019-11-04)
Polyamines (PAs) are natural aliphatic amines involved in many physiological processes in almost all living organisms, including responses to abiotic stresses and microbial interactions. On other hand, the family Leguminosae ...
