Abstract:
... Organophosphate resistant Typhlodromus pyri were exposed to deltamethrin in replicated orchard plots from 1986-90. Treatments of 6.3, 3.1, 1.7 and 0.8 g active ingredient (ai) ha-1 deltamethrin were applied 14 times over the 5-year period; a 12.5 g ai ha-1 treatment was discontinued in 1989 after eight applications. Few phytoseiids were found in the plots receiving the two highest rates of deltame ...

Abstract:
... The behavioural response of the predatory mite Phytoseiulus persimilis to volatiles from several host plants of its prey, spider mites in the genus Tetranychus, was investigated in a Y-tube olfactometer. A positive response to volatiles from tomato leaves and Lima bean leaves was recorded, whereas no response was observed to volatiles from cucumber leaves, or leaves of Solanum luteum and Solanum d ...

Abstract:
... Biological control of Thrips tabaci by the phytoseiid mites Amblyseius cucumeris and Amblyseius barkeri was investigated on glasshouse parthenocarpic cucumbers. The mite species were used in combination and singly. Successful thrips control was obtained with A. cucumeris alone, whereas control was not reliable with A. barkeri alone nor with the combination of A. cucumeris and A. barkeri. The estab ...

Abstract:
... Experiments conducted to evaluate the suitability of T. evansi as a source of food for P. persimilis revealed that the primary factor responsible for the low oviposition rate and survivorship of the predator when fed T. evansi was the low amount of food ingested. P. persimilis detected and initiated feeding on T. evansi equally as well as on T. urticae. However, a feeding depressant was apparently ...

Fresh cylinders with prey are placed at regular intervals on tops of older ones and predators will migrate upward. Empty cylinders at ...

The initial populations were established by mixing a variety of laboratory colonies, and adding a few individuals from recently collected field colonies. One population was treated alternately with azinphosmethyl ...

Abstract:
... Cases of developed resistance in apple arthropods in North America, including pests and natural enemies, are reviewed with emphasis on the past 20 years since organophosphate (O-P) insecticides were first widely employed. During this period, no key pest, including the codling moth, Laspeyresia pomonella L., has developed resistance to the O-P compound, azinphosmethyl, while a variety of secondary ...

Abstract:
... Most predatory mites of the family Phytoseiidae are considered, on karyological evidence, to reproduce by arrhenotoky. The haploid males are reported to have three or four and the diploid females six or eight chromosomes, respectively, according to the species. Evidence is presented which supports the hypothesis that males of Metaseiulus occidentalis (Nesbitt) develop from diploid (fertilized) egg ...

Abstract:
... The photoperiodic effect on diapause of Phytoseius finitimus and the resistance of mites to cold temperatures were studied in laboratory experiments. Short light periods (8-h light and 16-h darkness) at relatively low temperatures induce diapause, especially when such periods begin at the egg or early-larval stage. The ovaries of females which were induced to diapause in the laboratory were not de ...

Abstract:
... Metaseiulus occidentalis (Nesbitt), a predatory mite, is better able to regulate low densities of willamette mites, Eotetranychus willamettei Ewing, in more complex communities. Willamette mite populations fluctuate more widely in amplitude in simple communities or where monoculture is practiced. Weedy grasses associated with grapevines increase chances for reliable and stable spider mite populati ...

Interrelations among temperature, moisture, and viability of grain, and mites, insects, and fungi were studied from 8,135 samples collected at monthly intervals from two 13.6—ton wheat bulks stored in a granary at Winnipeg, Manitoba for 8 years during 1959—67. The bins were fumigated once with phospine (PH₃) in August 1965, to determine the effect of the chemical on the existing relationships in t ...

Abstract:
... The interaction between Tetranychus urticae and Phytoseiulus riegeli on cucumbers was studied in several different experiments at two centres. It was shown that if the predator is introduced at a low prey population, elimination of the mites occurred before leaf-injury became sufficiently high to cause a reduction in cucumber yield. A theoretical pattern of mite control and leaf-damage is discusse ...
