Hives from the Langstroth type containing equal strength of honeybee colonies from the species of hybrid Carniolan were used. The research aims to increase the honeybee colonies' activities and maintain the strength and quality production by mounting a simple warming system into the hive. This study included primary studies on three methods of warming (pushing hot air, using thermal coil, and using halogen lamp) to determine the best method adapted with bee colonies. The in-hive temperature was adjusted to a minimum of 21 ºC through a heat sensor. The secondary studies were conducted to study the effect of the best warming system on bee colonies' temperature, strength (sealed brood area and a number of occupied frames), and productivity (honey and pollen areas). Results showed that the system containing halogen lamps was the best method adapted with bee colonies. The minimum and maximum ambient temperatures were at 3.00 am and at 2.00 pm, respectively. The average temperatures outside and inside the nest were (19.17, 20.15, and 21.6 ºC) and (36.63, 36.76, and 36.65 ºC) for unwintering (control), normal wintering, and with warming system, respectively. The mean values of (honey, pollen, and sealed brood areas, cm 2); and a number of occupied frames on the end of March were (745,606 and1958 cm 2); and 5 frames for unwintered hives (control) and (1043, 914, and 3456cm 2); and 14 frames for halogen warming system, respectively. The total cost of the fabricated warming system was about 21.9 LE/season. Significant increase in hive products; (honey, pollen, and sealed brood areas); and a number of occupied frames were detected when using a halogen warming system comparing with unwintered and normal wintered groups. While the productivity was increased by about 19.51% and 30.38% respectively for honey and pollen areas compared with the normal warming system.

These varieties were G. 45 (P1), G. 70 (P2), G. 86 (P4), G. 88 (P5), G. 89 (P6); G. 90 (P7), G. 77 (P10) were Egyptian cotton varieties, Pima 62 (P3) and Pima S6 (P8) were American varieties, as well as, Kar. (P9) was Russian variety, all these varieties belonging to the species Gossypium barbadense L. In the growing season of 2006, the ten parental varieties were planted and crossed in a half diallel mating design to obtain 45 F1 single crosses. The all genetic materials used in this investigation included ten parental varieties and their 45 F1 single crosses were evaluated in the 2007 growing season at Sakha Agriculture Research Station at a randomized complete blocks design with three replications. Gene action, general and specific combining abilities and heritability in broad and narrow senses were estimated for boll weight, seed cotton yield per plant, lint cotton yield per plant, lint percentage, number of bolls per plant, seed index, lint index and number of seeds per boll. The results showed that highly significant differences among all evaluated genotypes for all the studied yield and yield component traits. The mean performances of genotypes revealed that G. 86 (P4) had the highest mean values for boll weight, seed cotton yield per plant, lint cotton yield per plant and lint percentage. While, the Kar. (P9) was the best and had the highest means for seed index, lint index and number of seeds per boll. The results also indicated that, the mean performances of most the 45 crosses were better than their both parents. Such as, the crosses G. 90 x Kar.

The aim of this study to detect the quantity income pollen collected from clover and maize crops. Survey of the area vegetation showed that clover was the dominated crop in winter and some viacia faba been fields, while rice, maize and may be some cotton fields in summer. Nine colonies with 10 combs were used in this study. In general, the mean of collected pollen was higher in clover season than those in maize (103.924 and 77.981g in 2011, however, in 2012 it was 47.232 and 45.425 g\ 9 colony\3 days), respectively. Air temperature and relative humidity were also registered. The highest collected quantity of pollen reached its maximum values between 70% and 78% of relative humidity and 23 0 C and 25 0 C. The number of pollen loads increased as relative humidity (r = 0.109; 0.151) and temperatures had a strong negative influence on the collected pollen (r =-0.193;-0.375) in clover season. The pollen loads decreased positively with temperature (rs =-0.375,0.463 and 0.127) , negatively correlated with relative humidity (rs = 0.151,-0.391 and 0.248) in maize season. The high values of loading pollen were in clover than those in maize, it may be related with the long flowering of clover as well as the effect of climatic influences .
