Abstract

Population dynamics of the different mites associated with different stored products. The first year (2010/2011): Roomy cheese. The most abundant astigmatid mites on roomy cheese were T. putrescentiae, A. siro and Carpoglyphus lactis (L.). The obtained results indicate that the highest population density of astigmatid mites on roomy cheese was occurred during October (181.6 mite/ 250 g ) where there were significant differences between this period and all other sampling dates. The least numbers of astigmatid mites was observed at January, February, March (3.5, 0.66, 0.46 mite /250 g), respectively without significant differences among them. Regarding the non-astigmatid mites associated with roomy cheese, It was noticed that the population density was less than that of astigmatid mites, except during June as it most abundant than astigmatid once and the highest population density of non-astigmatid mites on roomy cheese was occurred at July month (97.5 mite/ 250 g) where there were significant differences between this period and all other periods, followed by values of June and September with significant differences among all. Buckwheat. The obtained results indicate that the highest population density of astigmatid mites, which represented by T. putrescentiae and Acarus siro on Buckwheat was occurred at July (113.3 mite/ 250 g) where there were significant differences between this period of study and all other sampling dates, followed by September and June (31.3 and 24.6 individuals, respectively), with significant differences among all. The least numbers of astigmatid mites was observed at January, February, March 2010; December and November 2011 (0.0, 0.0, 0.16, 0.3, 1.3 mite /250 g), respectively without significant differences among them. Regarding to non-astigmatid mites associated with oilseed cake, the obtained results indicated hat that he population density of these group of mites which represented by some individuals of tarsonemid and euopodid mites was less than that of astigmatid mites (123. mite individuals). Furthermore, it was found that that the highest population density of non-astigmatid mites on Buckwheat was observed during July 2011 (58.1 mite/ 250 g ) where there were significant differences between this month and all other months of study, followed by August, June and September with significant differences among all, the least numbers was observed at November, December, January, February, March, October and April (0.0 , 0.0 ,0.0 ,0.0, 0.0, 1.1, 3.1 mite /250 g), respectively without significant differences among them. Wheat hay. The obtained results showed that the highest population density of astigmatid mites in wheat hay was occurred at August month (113 mite/ 250 g) where there were significant differences between this month and all other months, followed by values of July, September and October with significant differences among all. The least numbers of astigmatid mites was observed at February, March, January and December (0.0, 0.0, 0.3, 2.5 mite /250 g) respectively without significant differences among them. On the other hand, the population of non-astigmatids density was less than in the abundance than those of obtained astigmatid mites recording 269.3 mite indiduals.The study also indicate that the highest population density of this mites group was observed during August (156.48 mite/ 250 g ) where there were significant differences between this month and all other months, followed by values of July and September with significant differences among all. The least numbers of predacious mites was observed at February, January, March (0.0, 0.0, 0.0 mite /250 g), respectively without significant differences among them. Wheat bran. The current study indicate that the highest population density of astigmatid mites in wheat bran was occurred at August month (244.2 mite individuals / 250 g) where there were significant differences between this month and all other months, followed by values of July and September with significant differences among all. The least numbers of astigmatid mites was observed at February, January, March and December (0.0, 0.0, 0.8, 2 mite /250 g) respectively without significant differences among them. When taken the non-asigmatids associated with wheat bran in consideration, results showed that its population density was less abundant than that of non-astigmatid mites (349.8 mite members). The data also indicate that the highest population density of nonastigmatid mites in was observed during August (201.3 mite individuals / 250 g) where there were significant differences between this month and all other months, followed by values of July and September with significant differences among all. The least numbers of non-astigmatids was observed at February, January, March and December (0.0, 0.0, 0.0, 0.6 mite /250 g), respectively without significant differences among them Corn flour. The obtained results indicate that the highest population density of astigmatid mites on corn flour was occurred at August month (485.3 mite/ 250 g) where there were significant differences between this month and all other months, followed by values of July and September with significant differences among all. The least numbers of astigmatids was observed at February, January and March (0.0, 0.5, 0.8 mite /250 g) respectively without significant differences among them. Regarding to non-astigmatids associated with corn flour, the obtained results indicated that its population density was less than that of astigmatid mites i.e. (381.5, 1003.1 mite, respectively).The obtained data indicate also that the highest population density of non-astigmatid mites in was occurred at August month (130.6 mite/ 250 g) where there were significant differences between this month and all other months, followed by values of July and September with significant differences among all. The least numbers of non-astigmatid mites was observed at February, January, March and December (0.0, 0.0, 0.0, 0.76 mite /250 g), respectively without significant differences among them. The obtained results show the population density of astigmatid and non-asigmatid mites associated with biscuit along 12 months. Biscuit. The current stud indicate that the highest population density of astigmatid mites on biscuit was occurred at August month (301.9 mite/ 250 g ) where there were significant differences between this month and all other months, followed by values of July and September with significant differences among all. The least numbers of astigmatid mites was observed at February, January, March and December (0.0, 0.0, 1.1, 1.6 mite /250 g) respectively without significant differences among them. Regarding to non-astigmatid mites associated with biscuit, results indicated that its population density was less than that of astigmatid mites (238.8, 635.4 mite individuals, respectively). Furthermore, the study also indicate that the highest population density of non-asigmatid mites was recorded at August month (132.1 mite/ 250 g) where there were significant differences between this month and all other months, followed by values of July and September with significant differences among all. The least numbers of non-astigmatid mites was observed at February, January, December and March (0.0, 0.0, 0.16, 0.5 mite /250 g), respectively without significant differences among them. I-B-2- The second year (2011/2012) Roomy cheese The obtained results showed that the highest population of astigmatid mites on roomy cheese was recorded during August 2011 (959.5 mite individuals / 250 g) as, there were significant differences between different sampling dates of the current study, followed by July and June with significant differences among all. The least numbers of astigmatids mites was observed during February, January and March (0.3, 0.3, 0.5 mite /250 g), respectively without significant differences among them. Regarding to non-astigmatid mites associated with roomy cheese, results in same previously mentioned table indicated that the population density of this group of mites was less than that of astigmatids i.e. (415.68 mite’s members). Furthermore, the highest density of non-astigmatid mites in was occurred at August (246.8 mite/ 250 g) where there were significant differences between this month and all other months, followed by values of July and June with significant differences among all. The least population of non-astigmatid mites was recorded at February, January, March and December (0.0, 0.0, 0.16, 0.16 mite /250 g), respectively without significant differences among them. Buckwheat The highest abundance of astigmatids on buckwheat as determined in the current study was observed during August 2011 i.e. (266.6 mite/ 250 g) where there were significant differences between this month and all other months, followed by obtained during July and June with significant differences among all. The least abundance of astigmatids was observed at February, January, March 2012; December and November (0.0, 0.0, 0.0, 3.8, 4.9 mite /250 g), respectively without significant differences among them. Regarding to non-astigmatid mites associated with buckwheat, the population density was less than that of astigmatids (255.24 mite individuals).
