The effect of irrigation on the abundance of Empoasca vitis (Göthe) populations was investigated in four vineyards located in northeastern Italy. In two experiments, we compared leafhopper population densities in plots irrigated (micro-spray irrigation system) or nonirrigated. In another experiment, we studied the effect of various irrigation systems on E. vitis populations over two successive ...

The Montagne d'Ambre mountain range in northern Madagascar was surveyed for amphibians, reptiles, and small mammals. The rainforest of this region is geographically isolated from the continuous rainforest belt of northern and eastern Madagascar. A total of 24 amphibian, 46 reptile, and 12 mammal species was recorded over two months, by direct sampling and pitfall trapping. Despite previous coll...

The effects of treated and untreated water inlets with macrophytes on the improvement of water quality and zooplankton community were evaluated in a fish pond with continuous water flow. Water and zooplankton samples were retrieved at four sites during nine months. There were differences (p<0.01) between inlet water from fish pond and inlet water from canal with macrophytes, featuring higher co...

We describe two new species of Ctenocerinae (Pompilidae) from Asia, i.e., Ctenocerus srilankae Shimizu sp. nov. Sri Lanka and Paraclavelia arabiae Oman. These represent the first records Dahlbom, 1845 Haupt, 1930 in Asia. Two combinations a synonymy are proposed: fasciatus (Smith, 1851) (= Micropteryx fasciata Smith, 1851); decipiens (Arnold, 1932) Clavelia Arnold, 1932); Euclavelia 1932). disc...

In this study, four specimens belonging to Karaj mycoflora were examined. According to the results, two form – species; Diplosporonema delastrei, on Silene latifolia subsp. persica and Piggotia ulmi, on Ulmus sp. are reported with new names. For some of the identified fungal specimens, new hosts (matrix nova) are introduced. Moreover, many taxa such as , Marssonina kriegeriana on Salix sp.,  Se...

Systemic insecticides and application methods were evaluated in two trials that began in 2005 and 2006 for control of potato leafhopper (Empoasca fabae [Harris]) on four red maple (Acer rubrum L.) cultivars and rated annually through 2007. Treatments evaluated in this study included surface drenches of imidacloprid plus cyfl uthrin (Discus) or imidacloprid plus bifenthrin (Allectus SC), clothia...

The Asteraceae is a large family, rich in ornamental, economical, and medicinally valuable plants. current study involves the analytical pharmacological assessment of methanolic extracts three less investigated plants, namely Echinops ritro, Centaurea deflexa, Tripleurospermum decipiens, obtained by different extraction methodologies viz. maceration (MAC), ultrasound-assisted (UAE), homogenizer...
