This study aimed to investigate some of the morphological and reproductive characteristics of the queen honey bees rearing from emergency queen cells and larvae grafting method. The weight at the emergence of queens reared from one-day larvae was found to be higher than other groups (P <0.05). Morphological characteristics of queens according to rearing method showed significant differences of head width, forewing length and forewing width (P <0.05), whereas other morphological characteristics were found similar in different queen groups. No significant difference was observed between the groups in terms of cell length and width (P > 0.05). Wet ovary weights of the queens were weighed at 45, 51, and 49 mg rearing from emergency cells, 1-day-old and 2-day-old larvae, respectively. The number of ovarioles and spermatheca diameter of queens were found to be 268 and 1.14 mm, 296 and 1.21 mm, 285, and 1.16 mm rearing from emergency cells, 1-day-old and 2-day-old larvae, respectively (P <0.05). Consequently, the morphological and reproductive characteristics of queens reared from one-day-old larvae have higher values. According to the results of the study, although some morphological and reproductive features of local queens have low values, their importance should not be ignored in the sustainable future of beekeeping.

Significant Difference

The parasite, Nosema apis, was found to be widespread among feral populations of honey bees (Apis mellifera) in the south-west of Western Australia. The location, month of collection and whether the feral colony was enclosed in an object or exposed to the environment, all affected the presence and severity of infection. There was no significant difference in the probability of infection between managed and feral bees. However, when infected by N. apis, managed bees appeared to have a greater severity of the infection.

This experiment was carried out to study the internal temperature regulation of a colony of Africanized honey bees (AFR), compared with hybrid Caucasian (CAU), Italian (ITA), and Carniolan (CAR) bees, during the period of one year and different size hives located in a sub-tropical region. The instant internal temperature, 33.7 ± 1.5° C for the AFR, 33.5 ± 1.4° C for the CAU, 33.7 ± 1.5° C for the ITA and 33.8 ± 1.4° C for the CAR, did not show any significant difference (P>0.05). The maximum temperature (36.1 ± 2.3° C) was statistically different (P<0.05) from the minimum (27.6 ± 5.3° C). There was no difference (P>0.05) in the mean internal temperature, between the nucleus (31.7 ± 6.3° C) and the brood nest (32.1 ± 5.3° C) measured between two and four o'clock in the afternoon.

Disorientated larvae of the three castes of honey bees rarely occur under natural conditions; correct orientation is essential for survival in the worker and drone castes. The distinctive cells of the three castes were simulated by gelatin capsules with their end walls modified to give combinations of shape, ventilation, and texture. The effect of cell length and gravity was also tested. The major factors controlling larval orientation in cells are: (a) worker: primarily texture of cell end walls (i.e. basal end smooth, capping end rough) and secondarily shape of cell end walls (i.e. basal end round, capping end flat), (b) drone: texture of cell end walls, (c) queen: gravity and possibly the rough texture (i.e. the cocoon) of the lower end wall. Larvae defecate with their anterior ends touching the rough-textured end walls.

Effects of the Age of Grafted Larvae and the Effects of Supplemental Feeding on Some Morphological Characteristics of Iranian Queen Honey Bees (Apis mellifera medaSkorikov, 1929)The research was conducted at the apiary of the Faculty of Agriculture, Zanjan University in Zanjan, Iran. Queens were reared in 24Apis mellifera medahoney bee rearing colonies. The colonies were assigned to 4 grafting larvae age groups; 1 day old larvae, 2 day old larvae, and 3 day old larvae, and the last group reared emergency queen cells. The groups were divided into the 2 feeding groups: fed additionally and no fed. The effects of the age of the grafted larvae and the effects of supplemental feeding on 9 morphological characteristics of queens were measured. The results showed that the age of the larvae significantly affected the morphological characteristics of reared queens, and thus, their quality. Queens reared from 1 day old larvae were of the highest quality. These queens were significantly heavier (158.83 mg) and had significantly larger spermatheca (0.99 mm3) than queens reared from larvae 2 and 3 days old. Queens from emergency queen cells were of lower quality than queens reared from 1 day old larvae. However, queens from emergency queen cells were of higher quality than queens reared from 3 day old larvae. The supplemental feeding significantly increased most morphological characteristics of the reared queens. The different ages of the larvae did not significantly affect the wing length nor did supplemental feeding affect the wing length.

Indigenous and exotic honey bee species were evaluated for their hygienic behavior in the climatic condition of Peshawar Khyber Pakhtunkhwa, Pakistan. Colonies of equal strength from indigenous (Apis cerana) and exotic (Apis mellifera) species were selected for the study. The same colonies were tested in two seasons. Sealed brood were killed with different methods i.e pin killed and freeze killed. The uncapping of cells and brood removal was recorded at different intervals. Significant differences were recorded between hygienic behavior of both species of honey bees. Apis cerana showed significantly superior hygienic behavior than Apis mellifera in both seasons. At different intervals in both species significant differences were recorded. A significant difference was recorded after 12 and 24 hours between the species in both seasons. No significant differences were recorded after 48hours in both species. From the study it is concluded that indigenous honey bee species has superior hygienic behavior than exotic species.

Elevation of tributyltin (TBT) concentration in marine environment could affect targeted and non-targeted organisms at any lifestage. The present study aimed to determine median lethal concentration (LC50) and morphological effects of tributyltin chloride (TBTCl) on adult males and females of brine shrimp (Artemia salina). The adult males and females of A. salina were exposed to different concentration of TBTCl. Morphological condition of every A. salina individuals were observed under a microscope. Results showed the LC50 of TBTCl among adult males of A. salina was 146.99 ng.L-1 and for the females was 94.72 ng.L-1, respectively. The LC50 of TBTCl was significantly different among different sexes. There was also a significant difference in some morphological characters of males and females exposed to different TBTCl concentrations. These morphological changes include their total length, head width, abdominal width, and tail width after the 24hr exposure to TBTCl. These results suggested that suspensions of the TBTCl were toxic to Artemia, most likely due to the formation of benign TBTCl aggregates in water. However, the mortality increased with extended exposure to 24hr. Highest mortality occurred at 200 ng.L-1 TBTCl; 43.33% for male and 90% for female (LC50<150 ng.L-1) for both. Depended on this the female was more sensitive for TBTCl toxicity test when compared to male. These effects were attributed to changes in morphological characteristics of the body A. salina.

Measuring morphological characteristics of honey bee, <em>Apis mellifera</em>, at different times is important to assess the degree of race purity, to predict colony productivity, and to understand environmental impacts on honey bees. The study aims to characterise current honey bees of Northwest Egypt, namely El-Behera governorate, and to track occurred changes to their morphological characteristics since 2007. Samples of honey bee workers were collected from four districts in El- Behera governorate. Nine body and six wing characteristics were measured. Morphological characteristics of honey bees belonging to these districts were previously measured during 2007. To track changes, a comparison between new (2014) and previous (2007) measurements of morphological characteristics was done. The current bees of El-Behera are slightly larger than those of 2007, emphasising no reduction in colonies productivity. There is evidence that environmental factors have not caused much stress on the colonies since 2007. The results of this study are useful in providing understanding of the current state of bees in Egypt, and the likely improvement of future beekeeping.
