The South American fruit fly : an important pest insect with RNAi-sensitive larval stages [PDF]

open access: yes, 2019
RNA interference (RNAi) technology has been used in the development of approaches for pest control. The presence of some essential genes, the so-called "core genes," in the RNAi machinery is crucial for its efficiency and robust response in gene ...

First Assessment of Genetic Damage in the Speckled Cockroach (Nauphoeta cinerea) After Consumption of Lettuce (Lactuca sativa) Cultivated and Commercialized in Northeastern, Brazil

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT This study reports, for the first time, the use of the speckled cockroach Nauphoeta cinerea as a promising bioindicator for genotoxic monitoring. It was validated through control groups (both positive and negative) in addition to testing lettuce (Lactuca sativa ) samples from public street markets consumed by N. cinerea specimens in Pernambuco,

Insights on the nutritional ecology of a nocturnal pollinating insect

open access: yesInsect Science, EarlyView.
Nutritional ecology examines the environmental effects on nutritional needs, food intake and foraging behaviors, and the use of nutrients ingested by animals. Among insects, Lepidoptera are often considered opportunistic foragers that visit a wide variety of available flowers, although with some preferences.

Isotopic N,N-Dimethyl Leucine-Based Mass Spectrometric Quantification of Metabolites Following Copper Exposure

open access: yesBiomolecules
Crustaceans are particularly sensitive to copper toxicity, and although the downstream effects of increased copper exposure on the metabolome are often postulated and observed, they are rarely measured.
