Mejoramiento de micoinsecticidas: un enfoque desde la interacción entre la cutícula de insectos y los hongos entomopatógenos [PDF]
, 2019 Los insecticidas de contacto, sean químicos, físicos o biológicos, encuentran en la cutícula del insecto hospedador la primera barrera a la penetración. La misma está formada por varias capas, de afuera hacia adentro: la epicutícula, la procutícula y la ...

Effect of the microbiome on pathogen susceptibility across four Drosophilidae species
Insect Science, EarlyView.Four Drosophilidae species were used to investigate how variation in the host microbiome influences susceptibility to infection. Microbial composition and abundance differed among species and treatments. The effects of microbiome manipulation on host survival were both species‐ and pathogen‐specific.

Insect Science, EarlyView.In this study, we examined whether realistic ozone concentrations can interfere with sexual communication in the insect pest Plutella xylostella, the diamondback moth. Ozone exposure caused a degradation of pheromone components, leading to significant changes in blend composition and component ratios.

Insect Science, EarlyView.Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived airborne semiochemicals. Egg‐borne bacterial symbionts, and Serratia marcescens in particular, produce odorants which attract gravid female flies and elicit oviposition.

Structure of Kalanchoë pumila Bak. leaves (Crassulaceae DC.)
Acta Agrobotanica, 2012 The structure of Kalanchoё pumila Bak. was studied with the use of stereoscopic, light, scanning and transmission electron microscopy. It was found that the chlorenchymatic tissue was divided into subepidermal small-celled mesophyll and large-celled ...

Extinction Debt Paid Off: The Demise of the European Polecat (Mustela putorius) in NE Iberia
Integrative Zoology, EarlyView.We studied a vanishing polecat population for a decade, until its ultimate demise, using camera trap and roadkill data, landscape descriptors and dietary and toxicological analyses.Polecat favoured farmland and avoided forests and water bodies occupied by the invasive American mink.

Matrine–Tea Saponin Synergism Involves Suppressed Detoxification and Digestion in a Leaf Beetle
Integrative Zoology, EarlyView.Tea saponin and matrine showed synergistic toxicity against Plagiodera versicolora. Combined exposure suppressed digestion‐ and detoxification‐related processes, while silencing the trypsin gene Pver105950 and chitinase gene Pver001190 increased larval susceptibility to tea saponin and matrine, respectively.
