Agricultural Research Center, Dokki-Glza, Egypt.Journal Article20061103The present work aimed to study: I Effect of colors on aggressiveness of
honeybee races. 2. Hygienic behaviour in the laboratory tests and the colony as
indication of controlling of brood disease and varroa mite. 3. Relationship between
aggressiveness and hygienic behaviour. 4-Ggrooming behaviour, and experience of
the bees for removed disease brood as quickly by mixed some races to another
colony races wtiich the bees didn’t learn the behaviour.
The results obtained showed that, the Egyptian honeybee colonies showed the
severest aggressivcness and the Carniolan hybrid and Italian colonies show more
aggressiveness than the other colonies of pure races. The races of honeybee
colonies showed that, the severest aggressiveness to red and purple colors but the
inferior aggressiveness to wtìite and yellow colors. Highest value of hygienic
bahaviour was in Egyptian colonies followed by FI Italian and Fi Camiolan colonies
but the lowest value was in Carniolan colonies.
The relationship between aggressive behaviour and hygienic behaviour in the
honeybee colonies, showed that Egyptian honeybee colonies caused high aggressive
behaviour (93.61%) and hygienic behaviour (94.79%), on the contrary the Italian
honeybee colonies caused aggressive behaviour (17.23%) and hygienic behaviour
(47.52%$
There was a positive correlation between aggressive behaviour and hygienic
behaviour for the honeybee races in the expenments.
Highest grooming behaviour was found in Egyptian race, followed by Italian
hybrid, Cambian hybrid. On the contrary, the lowest grooming behaviour was found in
Camiolan and Italian race. While addition Egyptian sealed worker brood in the other
colony races, the debris mites maybe occurred as a result of attacking this mite by
mandibles of workers bees and this behaviour (grooming behaviour) is more of FI
Italian and FI Carniolan.
On the other hand addition Egyptian sealed worker brood in Cambian, Italian, Fi
Carniolan and FI Italian colonies caused increase of resistance mechanism to
Varroasis reached 1421, 27.3, 28.57 and 26.32%. respectively.https://jppp.journals.ekb.eg/article_235358_ba04a6cead8e843ae86438079a209099.pdfMansoura University, Faculty of AgricultureJournal of Plant Protection and Pathology2090-3677311220061201INFLUENCE OF PREY TYPES AND TEMPERATURES ON THE BIOLOGICAL ASPECTS OF THE PREDATORY MITES Cheyletus malaccensis OUDEMANS AND Neoseiulus Baken (HUGHES).7963797223536010.21608/jppp.2006.235360ENM.

Data showed that the predator mite Ch. malaccensis passed through one

consumption of certain vegetables for two species of land snails, Thebia pisana and

the two mentioned species. The results proved that the lettuce was the most
preferable for the two species fdlowed by cucumber and carrots. In addition, the
gained data cleared that the squash was the lowest preferable for the tested species.
The consumption as a percentages were (45.45% and 46.1%) for lettuce, (20.9% and
14.6%) for cucumber, (182% and 25.8%) for carrots and (15.5% and 13.5%) for
squash for the two tested species T. pisana and Eobania vemiiculata respectively. For
the effectiveness of the concentrations used 0.06% and 0.11% of vertimec (1.8% EC)
against the same mentioned species, the results revealed that the mortality went up to
100% for both species at 0.11% concentration. Meanwhile, the concentration 0.06%
gave 40% and 45% mortality for Thebia pisana and Eobania venniculata respectively.

farm of Sakha Agricultural Research Station (Katr El-Sheikh Governorate) which
occupies the northern pari of Delta. Bird damage was assessed once every five deys
just after sunflower anthesis until harvest. Damage chronology due to birds was
similar in both seasons1 concentrating within the first 25 days after anthesis when the
seeds were in the dough stage of development and amounted 75% of all damage.
However, bird accumulated damage was quite low (25%) during 20 days before
harvest. Peak bird damage occurred 15 days after anthesis. Type of damage in
periphery and interior plots in two seasons was similar. Bird monitoring using
binocular revealed that the house sparrow, Passer domesticus niloticus L. dominated
the crested lark, Galedda cristata L, with 87% and 13%. respectively. In both
seasons, 70% of damage occurred on sunflower heads with green and green-yellow
bowls, and 84% occurred when heads were halt-inverted.https://jppp.journals.ekb.eg/article_235379_1aa3cea6d83340a1cde13d47a5f48411.pdfMansoura University, Faculty of AgricultureJournal of Plant Protection and Pathology2090-3677311220061201FORMULATION AND EVALUATION OF METHOMYL AS MOLLUSCICID AGAINST Monacha cartusiana UNDER LABORATORY AND FIELD CONDITIONS.8027803323538210.21608/jppp.2006.235382ENM.

successes of honeybee virgin queens were studied, such as: type of receiver colony
race, introducing methods of virgin queen, presence of brood and their stages in
receiver colonies for acceptance and mating of honeybee virgin queens.
Results showed that carniolan bee colonies accepted the highest percentage
(96.67%) of the introduces virgin queens, followed by both the first carniolan hybrid
colonies and Italian colonies (93.33%), the lowest significant percentage of the
accepted queens was recorded for the Egyptian virgin queens (70.00%).
Concerning pre-mating periods of the introduced virgin queens, results
revealed that there were no significant differences among periods of pre-mating
required by the introduced virgin queens received by different bee colonies.
Results of mating ability of the introduced virgin queens, Italian bees
encouraged the highest percentage (78.88%). However queens introduced cambian
and Egyptian bees colonies mated by the lowest percentage 65.92, 5416%
respectively.
Recording postmating periods of the tested queens showed that queens
introduced to carniolan bees recorded a shortest penod (2.78 days), while the longest
penod (3.37 days) was recorded to the first Italian hybrid.
Results revealed that the highest percentage of acceptance (96.67%) was
noticed with using half comb cage, while applying direct introducing method resulted
in a lowest percentage (36.67%) of acceptance of the introduced queens.
Through two years revealed that introducing virgin queens to the colonies have
mixed brood resulted in acceptance of the introduced virgin queens was the highest
rate (86.67 and 90.00%, respectively). On the contrary introducing virgin queen to
colonies having only sealed brood resulted in the lowest acceptance percentage
(66.67 and 63.33). Pre-mating period of the introduced virgin queens showed that the
shortest period with introducing to the colonies of the colonies of the mixed brood , it
was 3.06 days while with queen introduced to colonies having no brood 3.73 days.
Mating success percentage should that although queens introduced to the colonies
having mixed brood mated by the highest percentage (84.72%). Also1 in this colonies
(mixed brood) helped in shorting the post mating periods of the introduced queens.
The highest acceptance percentages through two years study (96.67 and
93.33% respectIvely) were recorded with introducing virgin queens to colonies 3
combs. However introducing virgin queens to colonies of 10 combs resulted ¡n
decreasing acceptance level of these queens (53.33 and 56.76% for two years study).
Concerning pre-mating periods of introduced queen no significant difference were
found among different treatment. Recording mating success of the introduced queens,
showed that queens introduced to colonies of 5 combs mated by the highest rate
78.88%, while the lowest level mating success (62.22%) was associated with those
queens introduced to colonies of 10 combs.https://jppp.journals.ekb.eg/article_235388_58c2590a9131bc742e657a0d313dce63.pdf
