In this study, 12 morphological characteristics were measured on worker bee samples collected from seven different locations covering the territory of Republic Serbia. The measurement of 11 angles on the front wing and cubital index was done with stereo microscope Leica XTL-3400D, and software package IL 1009 in accordance with the standard method. The results showed significant differences between the groups of bees and investigation of angles on the forewing could be contributed to a clearer separation of groups of bees inside domestic population.

Abstract The spotted lanternfly, Lycorma delicatula, is an introduced plant hopper that causes significant damage to host plants in the United States. Because of its affinity for tree of heaven, Ailanthus altissima, control efforts have focused on the use of the systemic insecticide, dinotefuran, in designated trap trees. There is concern about exposure to this pesticide by non-target species, especially honey bees, Apis mellifera, via lanternfly honeydew. Therefore, honey bee colonies were established in areas of high densities of trap trees and samples of honey, bees, and beeswax were collected in May, July, and October of 2017 for analysis. Samples were extracted by the QuEChERS method and analyzed using high-performance liquid chromatography with tandem mass spectrometry to determine the presence and quantity of dinotefuran. Additionally, honeydew from lanternflies was analyzed for dinotefuran and informal observations of trap tree visitors were made. None of the worker bee, wax, or honey samples indicated detectable levels of dinotefuran; however, honeydew samples collected did contain dinotefuran above the detection limit with amounts ranging from 3 to 100 ng per sample. The lack of dinotefuran in honey bee products matches the general absence of honey bees at trap trees in informal observations.

Wohlfahrtia Magnifica

Introduction: The infestation of live humans and animals with dipterous larvae is called Myiasis. These larvae feed on the living or dead tissues, body fluids, and ingested foods of hosts at least for a certain period in myiasis cases. Case Presentation: During clinical examination, several larvae were detected in the perianal area of a goat at Selcuk University, Faculty of Veterinary Medicine, Internal Medicine Clinics. All visible larvae were cleaned by the clinician with the help of forceps. Ivermectin administered against larvae possibly penetrated deep into the wound. A topical antibiotic was also applied, and the wound was washed with an antiseptic solution. Several larvae were preserved in tubes including ethanol (70%) and transferred to parasitology laboratory. Firstly, the larvae were incised with a scalpel and cleared in potassium hydroxide (10%). Then, they were rinsed in distilled water, put into 70% ethanol for dehydration, and stored in 99% ethanol until dissection. The larvae were morphologically examined under a stereo microscope and dissected. The larvae were identified as third instar larvae of Wohlfahrtia magnifica according to the morphological characteristics of cephalo-pharyngeal skeleton, anterior spiracles, and peritremes. Conclusion: It should be kept in mind that in myiasis cases, early diagnosis is a very important factor in preventing deep tissue loss.

The paper presents a result of the simulation of the post-bending process of the pipe billet, using the MSC.Marc software package. It was shown that the use of a standard method for carrying out post-bending process leads to the formation of various defects, such as a variable gap between the edges along the pipe axis, vertical waves and bends at the edges, as well as a decrease in a sheet thickness on the edges.

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.

Royal jelly (RJ) is an acidic yellowish-white secretion of worker honey bee glands, used as food material of worker bee larvae for the first three days and queen bee larvae for the entire life. It is commercially used in cosmetics and medicinal industry in various parts of the world. This study determined the queen cell acceptance rate and RJ production difference among Italian and Carniolan bee races. Furthermore, the effect of plastic cup cell priming media, diets and seasons were tested on the larval cell acceptance rate and RJ yield of both races. The results indicated that average queen cell acceptance rate was significantly (p<0.001) higher in Italian race (75.53 ± 1.41%) than Carniolan race (58.20 ± 1.30%). Similarly, mean RJ yield per colony significantly (p<0.001) differed between both bee races, which were 13.10 ± 0.42 g and 9.66 ± 0.43 g, in Italian and Carniolan races, respectively. Moreover, priming media, diets and seasons significantly (p<0.001) affected queen cell acceptance rate and RJ production of both bee races. This study would help breeders to select the bees with higher-level of queen cell acceptance rate and RJ production in the future.

During a whole year (March 2003 to February 2004), several filters that capture airborne particles were collected from seven sampling sites spread throughout the Ptolemais-Kozani region (Western Macedonia), northern Greece. Environmental Scanning Electron Microscopy (ESEM), coupled with Energy Dispersive X-Ray analysis (EDX) was employed for the characterisation of the airborne particles. A classification of these airborne particles is attempted in this study. Aerosols with various morphological characteristics (angular, irregular, rounded, spherical, spheroidal, acicular), variable size (mostly between 5ßm and 20pm) and composition (aluminosilicates, oxides, carbonates, sulphates, metallic) were recognized. The airborne particulates were also categorized according to their origin. Geogenie, biogenic, anthropogenic (mainly fly ash released from lignite-fired power plants), carbonaceous and metalliferous (mainly iron and copper enriched) were the main categories. A database of characteristic airborne particles from Kozani area is being created using a simple software package, in order to help similar studies in the future.

Significant Difference

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.
