Environmental monitoring of economically important invertebrate pests in Bramley apple orchards in Northern Ireland
Journal Title: International Journal of Environmental Science and Technology - Year 2006, Vol 3, Issue 1
Abstract
Apple orchards are host to many species of both pest and beneficial invertebrates. Many of the pest species can cause severe economic damage if populations are left unchecked. Within Northern Irish Bramley apple orchards only four species are deemed to be of economic importance; Panonychus ulmi, Aculus schlechtendali, Rhopalosiphum insertum and Archips podana. Little information exists on the current population status and economic damage potential of these four pests. The population levels of these species and their potential to cause economic damage on the Bramley fruit is therefore discussed in regard to current economic spray thresholds.

Production of biosurfactant from Iranian oil fields by isolated Bacilli
Crude oil and water samples were collected from selected Iranian oil reservoirs. Experimental works were carried out in laboratory conditions. The samples have been grown on PYG medium and incubated at 30-80 0C. Thirty-s...
Preliminary assessment of heavy metals levels of soils of an oil field in the Niger Delta, Nigeria
This communication presents the results of preliminary investigation of the characteristic levels of heavy metals in surface soils of an oilfield in the Niger Delta. The results indicate higher concentration of the follo...
Toxic effect of Pb, Cd, Ni and Zn on Azolla filiculoides in the International Anzali Wetland
The limitation of plant growth in the polluted mediums can be used as a factor to determine of plant tolerance and the toxic effect of these mediums. In this work, the effect of Pb2+, Cd2+, Ni2+and Zn2+ (individually) on...
Estimation of number of deaths associated with exposure to excess ambient PM10 air pollution
The respirable particle matter (PM10) concentration in urban areas has been a chronic cause concern and principal reason for increased morbidity rate among resident population. The present study aimed at estimating a dis...
Comparison of the biological NH3 removal characteristics of a three stage biofilter with a one stage biofilter
A three stage and a one-stage bench-scale biofilter with effective heights of 129 cm filled with same type of packing material were operated at different influent concentrations of ammonia in order to investigate their p...
