“…Smith, 1953;van Rooyen, 1966). It is presumed to be native to the Orient, where citrus also originated (Fleschner, 1952;Ebeling, 1959). It is currently con sidered the most important pest of citrus in California (Ebeling, 1959;Munger, 1963).…”

The literature pertalOlOg to the bionomics of some of the mos t important tetranychids is r~viewed. Considerable attention is paid to the possihiliries of spider mites reaching pest le~els /as a 'resu lt of environmental factors. It is concluded that more infor--m ation is needed on economic injury levels of various species on d ifferent crops and under various climatic conditions. The in-I fluences of cultural practices and their interactions as related to population development of tetranychids also need more i tu dy. Furthermore, work is need~d on the influence of climatic conditions on development of retranychid mite populations together with possible predictability 'of outbreak situations. Finally; we need to know more about ·th)e fundamental relations between the host-planr-qualiry and spider mite development, and the, impact of spider mites on the development .of their .host p lants.

“…Peaks were relatively low in 1984 and even lower in 1986, but in 1985 they were high on both citrus varieties, except where E. stipulatus was established and was the dominant phytoseiid species. We do not know whether the very low CRM numbers in 1986 were the result of conditions unfavorable to increase of this mite, such as a slight alteration in chemical composition in the tree foliage (Fleschner, 1952(Fleschner, , 1958a, or whether predation by phytoseiids could have been the major factor responsible. Other possible biotic mortality factors not critically studied include CRM virus disease and Stethorus picipes.…”

“…The possibility must be considered that the malathion itself led to increased CRM levels, higher than those observed in the untreated plots, either by changing the chemistry of the leaf (Fleschner, 1952(Fleschner, , 1958aSaini and Cutkomp, 1966;White, 1984) or by hormoligosis (Luckey, 1968) -a direct stimulation of the reproductive potential of the mites. A stimulating effect of malathion on CRM populations was shown by Jones (1983 ) and on citrus thrips by Morse and Zareh ( 1991 ).…”

McMurtry, J.A., Morse, J.G. and Johnson, H.G., 1992. Studies of the impact of Euseius species (Acari: Phytoseiidae) on citrus mites using predator exclusion and predator release experiments. Exp. Appl. Acarol., 15: 233-248.To create plots with differential levels of Euseius, malathion sprays, highly toxic to phytoseiids but of low toxicity to citrus red mite, Panonychus citH (CRM), and citrus thrips, Scirtothrips citri, were applied to blocks of "Valencia" oranges for three seasons ( 1984, 1985 and 1986) and "Eureka" lemons for one season ( 1985 ). Releases ofEuseius spp. were made in plots within the treated blocks. In 1984, CRM populations were highest in the treated/no release plot, lowest in the untreated and intermediate in the treated/Euseius stipulatus-release plot. In 1985, CRM populations were high in all plots in the oranges (including the E. tularensis release) except the E. stipulatus-release plot, and in all plots in the lemons except the untreated. Euseius releases in the lemons had no effect, apparently because they were followed by very hot weather. In 1986, CRM was very low in all plots. Euseius stipulatus became the dominant phytoseiid species even in the E. tularensis-release plots after a few weeks, indicating that this species colonized more readily and spread to other trees more rapidly than did E. tularensis. The results support the hypothesis that E. stipulatus is an important mortality factor contributing to CRM control at low levels. Euseius stipulatus also may have a negative impact on the citrus rust mite, Phylloeoptruta oleivora. Citrus thrips populations were low during the entire study period and did not differ significantly between plots.

“…Although this seems to be the principal reason, other insecticide-related factors as well as poor weed control could also be involved. A major factor in some instances may be a stimulation of T. urticae reproduction by the insecticides, acting either directly on the mite or indirectly by altering host plant physiology (Fleschner, 1952;Jones & Parrella, 1984). Laboratory investigations with dichlorfos and a pyrethroid on T. urticae under controlled conditions failed to validate the above hypothesis (data not shown).…”
