Red scale were reared in the laboratory on disks cut from lemon leaves floated on distilled water in plastic vials. Scales could be reared to maturity on the disks and females would produce crawlers. Rates of development measured at four temperatures using the leaf disk method were similar to data reported by earlier authors. Unfertilized females were found to remain alive and could be fertilized up to 16 weeks after the second moult. On the average, the longevity of unfertilized females was shown to be 3.5 weeks longer than that of fertilized females. The fecundity of females collected from the field was measured at a series of constant temperatures. Estimates of the capacity for increase (rc) and the innate capacity for increase (rm were obtained at four temperatures. Both these statistics were shown to be greatly influenced by temperature; rc was found to be an underestimate of rm at higher temperatures.

Discrepancies in the degree of biological control of insect pests where the food plant species of the host were the only known variants in the environment have been subjects of scattered observations in the literature by Morgan (1910), Compere (1936), Gilmore (I938), and others.A long period of speculation on the existence of strains of California red scale, Aonidiella aurantii (Mask.) immune to attack by parasites culminated in the discovery by Flanders (1939a, 1942a) that the hymenopterous parasite Habrolepis rouxi comp. reproduced satisfactorily on A. aurantii on Citrus spp. but that verv few emerged from the same species of scale on sago palm, Cycas revoluta Thunb. This was considered to be the reason for Compere's early failure to bring the hymenopterous parasite, Comperiella bifasciata How, from the Orient to California on scale-infested sago palm; Smith (1942) concluded: “Recognition must be given to the possibility that the host plant may confer on the host insect a kind of immunity to parasitization”.

Mutual Tolerance

The work which is described in this paper was undertaken owing to the conflicting results of standard fumigation practice in Palestine as it existed up to 1932, so that it became evident that the response of the Black Scale to Palestine conditions called for investigation.Owing to the difference in climate between the Northern Coastal Plain and the Jordan Valley a series of parallel investigations had to be initiated, with the interesting results which Dr. Schweig and Mr. Grunberg have set forth.There seems little doubt that the growers in the Jordan Valley will have to change from summer to winter fumigation and that in Acre Sub-District even if the double fumigation now under trial is not practicable (and there is no reason wh y it should not be) fumigation will have to be completed by the end of July—otherwise the fruit of the last fumigated groves will be infested before the gangs can reach them. With regard to biological control, this would be pf more value for keeping down the Black Scale population on alternative hosts, such as Eucalyptus groves and roadside trees. Negotiations for the importation of Comperiella bifasciata are in progress, and if this proves possible it will be given a trial in the Jordan Valley and the Coastal Plain.It is unfortunate that the pressure of other demands on the time of a small staff precluded the investigation of the behaviour of the Black Scale in Jaffa Sub-District, but general observations show that it tends to react more in the manner of the Jordan Valley race than of that of the Northern Coastal Plain.All the orange-groves between Jaffa and Haifa are heavily infested with Aonidiella aurantii, and it will be interesting to see, in view of the observations on mutual tolerance contained in this paper, whether Black Scale spreading from Jaffa will drive out the Red Scale or fail to make headway agaipst it.
