Water Balance Components in Adults of Terrestrial Red Mite <I>Balaustium</I> sp. (Acarina: Erythraeidae)

Use of an alarm pheromone against ants for gaining access to aphid/scale prey by the red velvet mite Balaustium sp. (Erythraeidae) in a honeydew-rich environment.

This study shows that honeydew prompts arrestment and reduced activity, but not attraction, by the mite Balaustium sp. nr. putmani. When presented with short-range, two-choice bioassays, mites ceased their characteristic rapid crawling activity when they encountered honeydew-treated surfaces, resulting in them clustering around the honeydew. Approximately 80% of mites were retained by honeydew,...

A new species of chigger mite, Hannemania hegeneri (Acarina; Trombiculidae).

Simulation of Water Balance Components Using a Distributed Hydrological Model in Taleghan Watershed

Water changes information in the hydrological system, in time and space, as an environmental issue takes heed of managers and decision makers in watershed management and river engineering, which can be addressed by using spatially distributed modeling. In this study simulation of water balance components in Taleghan mountainous watershed is performed using the spatially distributed hydrological...

Functional response of the predatory mite Chileseius camposi (Acarina: Phytoseiidae) on densities of it prey, Panonychus ulmi (Acarina: Tetranychidae).

The functional response of the phytoseiid predator Chileseius camposi González y Schuster, 1962 (Acarina:Phytoseiidae) on densities of its prey Panonychus ulmi (Koch, 1836) was evaluated under controlled temperature (20 +/- 2 degrees C), relative humidity (75 +/- 15%) and photoperiod (16:8h L:D). A functional type II response was displayed (Holling's disk). Holling, Wolf transformation and Roge...

Trends in water balance components across the Brazilian Cerrado

We assess the water balance of the Brazilian Cerrado based on remotely sensed estimates of precipitation (TRMM), evapotranspiration (MOD16), and terrestrial water storage (GRACE) for the period from 2003 to 2010. Uncertainties for each remotely sensed data set were computed, the budget closure was evaluated using measured discharge data for the three largest river basins in the Cerrado, and the...
