Insect Growth Regulators For Insect Pest Control*, Hasan Tunaz, Nedi̇m Uygun Jan 2004

Insect Growth Regulators For Insect Pest Control*, Hasan Tunaz, Nedi̇m Uygun

Turkish Journal of Agriculture and Forestry

Insecticides with growth regulating properties (IGR) may adversely affect insects by regulating or inhibiting specific biochemical pathways or processes essential for insect growth and development. Some insects exposed to such compounds may die due to abnormal regulation of hormone-mediated cell or organ development. Other insects may die either from a prolonged exposure at the developmental stage to other mortality factors (susceptibility to natural enemies, environmental conditions etc) or from an abnormal termination of a developmental stage itself. Insect growth regulators may come from a blend of synthetic chemicals or from other natural sources, such as plants. The chemical composition of …

Growth Trends And Water Use Efficiency Of Pinus Pinaster Ait. In Response To Historical Climate And Groundwater Trends On The Gnangara Mound, Western Australia, Lindsay Bourke

Theses : Honours

In Western Australia, groundwater accounts for about 57% of Perth's water supply. The majority of this is from the Gnangara Mound, the largest superficial aquifer on the Swan Coastal Plain. Prior to the mid 1970's groundwater of the superficial aquifer reached a semi-steady state, however since this period levels have been steadily falling. This decline coincides with a dramatic change in Perth's climate, groundwater abstraction and maturation of pine plantations. The influence of pine plantations upon groundwater recharge is well understood, however there is paucity of information about groundwater use, in particular whether pines directly access shallow groundwater resources. This …
