This study focused on conservation biological control of pear psylla, Cacopsylla pyricola, in the Pacific Northwest, USA. We hypothesized that insecticides applied against the primary insect pest, codling moth Cydia pomonella, negatively impact natural enemies of pear psylla, thus causing outbreaks of this secondary pest. Hence, the objective of this study was to understand how codling moth man...
The common pistachio psylla, Agonoscena pistaciae (Homoptera: Psyllidae) is known as the key pest of pistachio trees in Iran. This study was carried out during three years to test the effect of dish washing detergent (Rika ® ) against this pest in a randomized complete block design with five treatments and four replicates. The treatments were including: 13500ml dish washing detergent per 1000 l...
High attraction is reported for yellow sticky traps to capture pistachio psylla. In pest management, it is important to forecast from the adult population density the density of other developmental stages in order to gain an estimate of the density in damaging stages. In 1998 and 1999, yellow sticky boards with 10150.15 cm were installed in two pistachio orchards in Borkhar district of Isfaha...

some oxime ether derivatives of α-ionone (4-(2,6,6-trimethyl-2-cyclohexen-1-yl)-3-buten-2-one) have been synthesized. reaction of 4-(2,6,6-trimethyl-2-cyclohexen-1-yl)-3-buten-2-ketoxime with various chloro and fluoro aromatic and hetero aromatic compounds gave the corresponding oxime ether derivatives via aromatic nucleophilic substitution (snar). the structures of these compounds were elucida...
In 1998 and 1999, adult population density of pistachio psylla and its sex ratio were determined weekly in two orchards with yellow sticky board traps and limb jarring. Also egg and nymphal population was determined on the leaves. By studying the seasonal population fluctuaions, the efficiencies of the two methods were compared. Meanwhile, using yellow sticky boards, diurnal activity of adults ...
Color sticky board traps are used in pest management for capture of adult insect, to estimate and predict population densities in later stages. Yellow sticky board traps showed high attraction for pistachio psylla. It is important to study these relationships for the right placement of traps. For each of three repetition in one year, four pistachio trees were selected randomly in one orchard. E...

functional response in natural enemies is affected not only by host and natural enemy characteristics but also, the application of pesticide to pest population can affected the parameters of functional response as well as efficiency of natural enemy. in this research, the side effects of two pesticides, hexaflumuron and pymetrozin and also acaricide spirodiclofen and plant extracts, caiotropis ...
