Abstract

This study was carried out at Mit Ghamr city, Dakahliya Governorate and El-Amar region Qaliubiya Governorate. This work was conducted
during two successive years (2010-2011) to discuss some morphological
and physiological characteristics and the productivity of Italian strain (Apis
mellifera ligostica) isolated in Suez and Carniolan strain (Apis mellifera
carnica) isolated in Manzala and there first hybrids to see the best of these
strains and hybrids as shown below:
1. Biometrical characters and measurements:
1.1. Biometrical characters of virgin queens:
1.1.1. Queen weight measurements:
The results indicated that, the Italian queen had the heaviest body
weight (176.6mg) followed by F1 Italian (161.2mg), then Carniolan
(159.3mg), whereas the F1 Carniolan queen had the lightest body weight
(159.0mg). There were significant differences between Italian strain and the
others. While, there were no significant differences among Carniolan, F1
Carniolan and F1 Italian.
1.1.2. Length of right forewing:
Data indicated that, the Italian queen had the longest forewing
(10.274mm) followed by F1 Italian (10.184mm), then F1 Carniolan
(10.042mm), while the Carniolan queens had the shortest forewing
(10.038mm). There were no significant differences between F1 Italian and
the others. There were significant differences between the Italian and each
of Carniolan and F1 Carniolan.
1.1.3. Width of right forewing:
Results indicated that, the Italian queen had the widest forewing
(3.456mm) followed by F1 Italian (3.376mm), then F1 Carniolan
(3.331mm), while the Carniolan queen had the narrowest forewing
(3.313mm). There were no significant differences between F1 Italian and the

others. While there were significant differences between the Italian and
each of Carniolan and F1 Carniolan.
1.1.4. Right ovary weight:
Data indicated that, the Carniolan queen had the heaviest right ovary
followed (3.978mg) followed by Italian (3.928mg), then F1 Carniolan
(3.808mg), while the F1 Italian queen had the lightest right ovary
(3.733mg), with no significant differences between them.
1.1.5. Number of right ovarioles:
Results indicated that, the Italian queen with highly significant
possessed the highest number of right ovarioles (157.4) followed by F1
Italian (146.6), then Carniolan (142.3), while the F1 Carniolan possessed
the lowest number of right ovarioles (125.6). There were highly significant
differences between Italian and the others. While, there was no significant
difference between the F1 Italian and Carniolan.
1.1.6. Correlation and regression among virgin queen characters:
Data specified that, Positive correlation coefficients calculated among
length, width of forewing and queen weight, also between length and width
of forewing, and between length of forewing and number of right ovarioles.
1.2. biometrical characters of worker bees:
1.2.1. Length of Proboscis:
Data cleared that, the F1 Italian worker possessed the longest
Proboscis (6.517mm) followed by Italian (6.502mm), while the F1
Carniolan and Carniolan were the shortest with the same proboscis length
(6.267mm). There were highly significant differences between F1 Italian
and both of Carniolan and F1 Carniolan, while there was no significant
difference between Italian and F1 Italian.
1.2.2. Length of right forewing:
The results cleared that, the Italian worker forewing was the longest
one (9.959mm) followed by F1 Italian (9.5mm), then F1 Carniolan
101
Summary
(9.321mm), while the Carniolan worker forewing was the shortest one
(9.309). There were highly significant differences between Italian and both
of Carniolan, F1 Carniolan, also there was significant difference between
Italian and F1 Italian, while there was no significant difference between
Carniolan and F1 Carniolan.
