This study looked at regulated deficit irrigation (RDI) on leafhoppers in the genus Erythroneura (Erythroneura elegantula Osborn, or western grape leafhopper, and Erythroneura variabilis Beamer) (Hemiptera: Cicadellidae), which are serious pests of cultivated grape (Vitis vinifera L.) in California. RDI is an irrigation strategy that reduces irrigation during a critical point in the phenology o...

This study used a partial sequence of the mitochondrial cox1 gene for reconstruction interrelationship adult and larval stages Spirometra obtained from Cerdocyon thous, Leopardus munoai, Canis familiaris, Didelphis albiventris Philodryas patagoniensis in Uruguay. The phylogenetic analysis showed that they were grouped with decipiens Americas high bootstrap support. According to recent studies, ...

In recent years, a change in the spatiotemporal profile of leafhopper populations has been observed, resulting persistent infestations cotton parcels throughout crop cycle. The need to investigate various causes this led present study, which aimed at identifying leafhoppers found on Ivorian basin. Collections were made 12 localities identification these samples revealed existence least three sp...

A study of the time course of penetration of 3H2O into whole worms suggests that worms immersed in a hypo-osmotic environment (15% artificial sea water) reach full exchange equilibrium more slowly than worms in an iso-osmotic environment (40% artificial sea water). The apparent water content, determined by dry mass, matches that determined by 3H2O exchange when worms are immersed for 24 h in 40...
