Abstract
C- The population density of C. ornatus has one peak of seasonal abundance in November during two successive years.
13-The population dynamics of three predator mites A. swirski; A. exsertus and C. ornatus on three grape varieties were positively correlated with average temperature while it were negatively correlated with the relative humidity during two successive years.
14-The population density of three predatory mites were positively correlated with the population density of five phytophagous mites during two successive years.
15-Population dynamics of fig bud mite, Aceria ficus cotte on two fig variety trees were carried out at Giza Governorate.
16-The population dynamics of A. ficus has two peak of seasonal abundance one in June and other in October on young leaves of Sultani and Adsi fig varieties during two successive years.
17-On old leaves of Sultani variety the eriophyid bud mite, A. ficus has two peaks of seasonal abundance one in July and other in November, while on the old leaves of Adsi variety it has two peaks in July and October. The individuals of A. ficus were appeared with little number in March and decreased in December. The eriophyid bud mite, A. ficus disappeared from January to March during two successive years.
18-The population density of A. ficus were significant positively correlated with average temperature while it
was negatively correlated with average relative humidity on young and old leaves of Sultani and Adsi fig varieties during two successive years.
19-Fig varieties exhibited considerable variability in their susceptibility to fig bud mite, A. ficus from which Sultani fig variety was the most susceptible to the infestation by fig bud mite, A. ficus than Adsi fig variety during two successive years.
20-Trees with mosaic symptoms, observed in almost all the fig growing areas in Egypt, which infested by mites were used to study:
I. Transmission of FMV by mites:
1-The fig bud mites (A. ficus) was succeeded to transmit the virus from diseased to healthy plants of Siltani and Adsi fig varieties. Results indicated that the percentage of transmission was higher in Sultani (60) than in Adsi plants (50).
2-The two spotted spider mite (T. urticae) was failed to transmit the virus.
3-The characteristic of FMV observed were light chlorotic spotting & mottling, mosaic & yellowing the leaves and malformation of the laminae.
II. Effect of number of viruliferous mites (A. ficus) per plant on virus transmission:
1- The number of infected plants were increased with the increase of the number of mites used.
2- Hundred percentage of Sultani and Adsi plant became infected when 20 viruliferous individuals of mites were used.
III. Development of mite population on healthy and virus-infected fig plants.
1-The numbers of mite, A. ficus were increased during the period from developed the first pair of infected leaves to complete the second one of Sultani and Adsi infected plants (5040 and 3884 individuals comparing with 4196 and 3506 individuals on healthy control plants, respectively) when 20 individuals were used.
2-The numbers of two-spotted spider mite were increased in healthy fig plants than in infected ones. On Sultani healthy leaves 6869 individuals were recorded, comparing with 7470 individuals on infected plants whereas on healthy Adsi plants 6181 individuals recorded comparing with 5386 individuals recorded on infected ones.
3-Transmission by grafting: the infectious nature of FMV was confirmed by graft-transmission test. Healthy and/or symptom less seedlings did not give any symptoms of mosaic when tested by bud-grafting.
21- Evaluation of some acaricide Challenger (chlorfenopyrol) 36% Sc at 40cc / 100 litres of water against the population of fig bud mite, A. ficus cotte under field condition at Giza Governorate revealed that the reduction in mite population after 28 days of spraying averaged 88.02%, while the percentage average was 81.05%,
78.46% and 69.21% for the recommended acaricides sumi mite (Ethoxazole) 10% FL; Tobas 10% EC (Penconazole) 10cc and sulphur 70% W.P. at concentration of 35cc; 10cc and 250 gr. 100 liter of water, respectively.
RECOMMENDATION
1-The final purpose of the present course of investigation is how to protect such fruit trees from the injurious attacks of the mite pests. For such purpose, detailed information about different pests must be any how, provided, which is, principally death with in the present work. Thus, we ought to start with the most dangerous and serious acarine pests, depending upon new concept about pest population management, instead of instantaneously killing of the pest individuals. The mites studied were chosen for such study, because of their serious and dangerous role in destroyed these fruit trees and their relation with virul diseases.
2-Recognizing the time of the annual peaks of seasonal abundance for each phytophagous spices, concerned in the time of starting the application of the suggested control program.
3-The recognized local predaceous mites, which is found in association with such phytophagous mite pests, are considered as the most successful natural enemies for these pests. Thus, it is recommended here to use them in control application programs.
4-The obtained data about the relationship between fig bud mite (A. ficus), two spotted spider mite (T. urticae) and FMV. So, several sources of resistance to mite and virus disease must be use.
5-Some acaricides and fungicides were used against A. ficus to determine the compound which more efficiency (Challenger 36% Sc).
