Biophysical Properties of Yellow Pigment Granules in the Oriental Hornet (Vespa Orientalis) Cuticle Biophysical properties of yellow pigment granules in the Oriental hornet (Vespa orientalis) cuticle By Marian Plotkin Tel-Aviv University, Sackler Faculty of Medicine Department of Physiology Digging activity Correlation between insolation and hornet flight activity Model of a cuticle segment of a yellow stripe Yellow colored cuticle Brown colored cuticle Yellow pigment granules structure Absorption of brown cuticle Absorption of yellow cuticle Exo- Yellow Endocuticle Pigment Layer Granules Reflectance of hornet cuticle liver functions in the Oriental hornet Xanthopterin identified in the pigment granules Dye Sensitized Solar Cell (DSSC) model Exo-endocuticle Transparent Electrode & Antireflective coating - Light absorbing pigment in Photochemical? barrel shape housing that increase the effective I3- 3I- surface area available for Hemolymph? absorption + Voltage buildup across a yellow Stripe Dye Sensitized Solar Cell (DSSC) Dye = Xanthoptherin 0.335% < ~11% Discussion 1) The oriental hornet brown/yellow pattern serves the obvious purpose of warning other animals that the hornets are venomous. 2) The yellow stripes protect the hornet from the harmful solar radiation similar to the role of melanin in the brown cuticle. 3) The Oriental hornet cuticle bears yellow-colored stripes composed of yellow granules. The yellow granule contains xanthopterin. This array of yellow granules maximizes the ability of the extensively conjugated xanthopterin to absorb a wide range of visible light extending up to UV light. 4) The hornets leave the silk cap 3 days prior to its full maturation. The ontogenesis from ovum to pupa requires about 25–30 days. So this would mean that the reproductive rate of the nest can be increased by 10% or more if the hornets leave the silk cap 3 days prior to its full maturation (since the empty cell can be oviposited again more quickly). 5) Liver-like functions are present in the pigment layer those functions are UV dependent. Discussion 4) The exocuticle serves as an antireflective coating allowing the absorbance of almost 99% of the solar radiation throughout most of the visible range. 5) This work suggests that hornet cuticle may act as an organic solar cell. This process helps the hornets harness the solar radiation in order to conduct its rigorous digging activity..

  • Testing the Efficacy of Some Methods Recommended
    Glaiim & et al Bull. Iraq nat. Hist. Mus. (2008)10 (3): 21-27 TESTING THE EFFICACY OF SOME METHODS RECOMMENDED ABROAD FOR CONTROLLING THE ORIENTAL HORNET, VESPA ORIENTALIS L., ATTACKING HONEY BEE, APIS MELLIFERA L., COLONIES IN IRAQ Murtadh K. Glaiim* Huda A. Mahdi** Hassan A. Ibrahim** *Department of Plant Protection, College of Agriculture, Kerbala University, Iraq. **State Board for Agricultural Research, Ministry of Agriculture, Iraq. ABSTRACT Some methods recommended abroad to control the oriental hornet, Vespa orientalis L., attacking the honey bee, Apis mellifera L., colonies were tested, with some modifications, for the first time under the Iraqi conditions. One of these methods was carried out by covering the hive entrance with a piece of queen excluder to prevent the hornet from entering the hive. Also, the position of hive stand was reversed to deprive the hornet from using the flight board as a stage for waiting and creeping toward the defending bees. The second method was carried out by fixing a cardboard cone as a bee passage at the hive entrance to hinder the entry of the hornet into the hive. Both of these methods were found to be unsuccessful to control the hornet. Also, the use of vinegar traps had an adverse effect, for only worker honey bees and dipterous insects, rather than the hornets, were trapped in large numbers. INTRODUCTION The oriental hornet, Vespa orientalis L., is a key pest attacking honey bee colonies in many countries (Ishay et al. 1967; Klein and Adler, 1996; Gomaa and Abd El-Wahab, 2006; Haddad et al., 2006). Beekeepers in different countries including Iraq have practiced many measures invented by the beekeepers themselves to control all the species of the genus, Vespa.

  • Carriage of Coliform Bacilli by the Oriental Hornet ( Vespa Orientalis
    68 CARRIAGE OF COLIFORM BACILLI BY THE ORIENTAL HORNET {VESPA ORIENTALIS FABR.). BY P. A. BUXTON, M.A., F.E.S., M.R.C.S. Fellow of Trinity College, Cambridge. THE large red Oriental Hornet (Vespa orientalis Fabr.) must be extremely familiar to all who served in Mesopotamia. The Rev. F. D. Morice, who has been good enough to identify my specimens, tells me that it can barely be distinguished from Vespa crabfo L., the European hornet, except by its colour. It is widely distributed in the Mediterranean countries up to lat. 47° N. and occurs S. to Abyssinia and Madagascar, E. to India, and also as an introduced species in certain parts of S. America. In Mesopotamia the nests are made in hollows in mud walls, under old roofs, in the brick sides of wells and similar situations. The hybernated females appear in the early spring, and workers are first seen in mid-June. During August, September and October they are exceedingly abundant and sometimes conceal from view the joints of meat on which they are feeding in the butchers' shops. They also devour all sorts of fruit, particularly fresh dates in the bazaars. It is a matter of common knowledge that this insect feeds on all forms of household refuse, especially faeces of men and animals, and the dried carcases that one finds so frequently on the edge of Arab towns. I once observed hundreds of workers gorging themselves at a stream of blood and putrid offal which oozed from beneath the door of the Jewish slaughter house in Baghdad; this was in September 1917.

  • 3Rd HELLENIC SCIENTIFIC CONFERENCE in APICULTURE- SERICULTURE Thessaloniki 21-22 April 2007
    3rd HELLENIC SCIENTIFIC CONFERENCE IN APICULTURE- SERICULTURE Thessaloniki 21-22 April 2007 HELLENIC SCIENTIFIC SOCIETY OF APICULTURE- SERICULTURE NUMBER OF DRONE CELLS IN THE NATURAL-BUILT HONEYCOMBS OF A. M. MACEDONICA Goras G., Dislis S., Konstas N., Thrasyvoulou A. Laboratory of Apiculture – Sericulture, Faculty of Agriculture, Aristotle University of Thessaloniki, . [email protected] Beekeeping as a biological agriculture requires the replacement of all of the honeycombs. Using frames with foundation comb provides uniformity with minimal structure of dronecells but biological wax is limited and it is not always free of residues. As a solution it could be proposed to “force” bees to build the frames without using foundation combs, but in this case, the number of dronecells would be higher. This number depends on the bee race but there in no paper that it refers to this characteristic for the indigenous of Greece. In this paper present the first data concerns the production of dronecells in beecolonies with and without foundation comb. The experimental group provided with frames with foundation comb, produced less drone cells (0,03% per bee colony) in relation to the second group, which built natural honeycombs and so produced more dronecells (20,6% per bee colony). These average numbers present significant differences and this is also occurs after the comparison of the number of worker cells that the two experimental groups produced. First group produced mainly worker cells (99,97% per colony), while the second group produced 79,3% worker cells per colony. Finally we can establish that in each experimental group there is a great variance among the colonies that concerns the number of dronecells, regardless of the use (CV% : 316,7%) or not (CV% : 67%) foundation combs.

They are primarily predators of other in- sects, and some species are known to attack and feed on honeybees (Apis mellifera L.), which makes them a serious threat to apiculture. Hornet species identification can be sometimes difficult because of the amount of intraspecific color and size variation. This has resulted in many species-level synonyms, scattered literature, and taxonomic keys only useful for local populations. We present a key to the world species, information on each species, as well as those intercepted at United States Ports of Entry during the last decade. Images of all the species and some of the subspecies previously described are also included. Resumen Los avispones (Vespidae: Vespinae: Vespa) son avispas sociales, depredadoras de otros insectos y algunas de las especies muestran cierta preferencia por abejas, incluyendo las abejas melíferas (Apis mellifera L.) convirtiéndose en una amenaza para la apicultura.

  • Oriental Hornet (Vespa Orientalis) As AFB Disease Vector to Honeybee (Apis Mellifera L.) Colonies
    Middle East Journal of Applied Volume : 06 | Issue :04 | Oct.-Dec.| 2016 Sciences Pages: 934-940 ISSN 2077-4613 Oriental Hornet (Vespa orientalis) as AFB Disease Vector to Honeybee (Apis mellifera L.) Colonies Elhoseny, E. Nowar Plant protection Dept., Fac. of Agric., Benha Univ., Moshtohor, Toukh, Qalubia, 13736, Egypt. Received: 30 Oct. 2016 / Accepted: 05 December 2016 / Publication date: 10 December 2016 ABSTRACT The present study was carried out in the honey bee laboratory of Faculty of Agriculture, Benha University, Egypt during two successive years 2014 and 2015 at the period from October to December to prove that the oriental hornet (Vespa orientalis L.) was considered as AFB disease vector to honeybee (Apis mellifera L.) colonies. Firstly, the number of oriental wasps in two Egyptian governorates (Qalubia and Menofia) were surveyed, then these nests were checked for AFB disease infestation. Results indicated that the mean number of collected oriental wasp nests was 13.5 and 13.0 nests in 2014 and 2015, respectively. And from the collected nests, 66 and 53.4 % were infected and showed typically symptoms of AFB during 2014 and 2015, respectivelly. Additionally, the mean ratio of infected oriental wasp larvae with AFB was 16.7 and 21.7% in the years 2014 and 2015, respectively. The mean number of oriental wasp combs per nest was higher in 2014 with 4.3 comb/nest than 2015 with and 3.8 comb/nest. After that, four bacterial isolates were isolated from the infected larvae and identified as Paenibacillus larvae using the molecular techniques. Key words: Vespa orientalis, Apis mellifera, AFB Introduction The Oriental hornet (Vespa orientalis L.) is a social insect belongs to the Vespidae family, it is a member of genus Vespa which constitutes true hornets, their nests were build underground and consisting of caste system dominated by the queen, nests contain multiple combs in which the colony lives (Ebrahimi and Carpenter, 2012).

Awad² 1Plant Protection Department, Faculty of Agriculture, Assiut University, Assiut, Egypt 2Zoology & Entomology Department, Faculty of Science, Assiut University, Assiut, Egypt [email protected]. Abstract: In the apiary of Assiut University, the oriental hornets, Vespa orientalis L., were trapped and collecting every three days by using modified wooden traps to know their fluctuation and population during their active season. Also, detect the differences on the morphology, ultra-structure, and behavior between the different casts (queen, daughter worker and male) of V. orientalis. In the present study, the fluctuation showed that hornet population began with a slight increase number during September which comprised about (12.3%). In October, a big jump occurred (52.5 %) in their number. By the first week of November, the number started to decrease (26.7%) and then disappeared at the second fortnight of November. Antenna plays an important and vital role during host finding and acceptance behavior in insect life. Like many insects, oriental hornet Vespa orientalis L., use antennal chemo- receptors to detect the hosts during its active seasons. Scanning electron microscope (SEM) studies showed five types of sensilla (Chaetica, trichoidea, basiconica, placodea and coeloconica) were distributed on the antenna of the three different casts of the hornet. These function of sensillae possibly as chemo-, and tactile receptors, responding to movements of the antennae. [Mohamed M. Khodairy and Azza A.

  • HUNTING BEHAVIOR of the ORIENTAL HORNET, Vespa Orientalis L., and DEFENSE BEHAVIOR of the HONEY BEE, Apis Mellifera L., in IRAQ
    M. K. Glaiim Bull. Iraq nat. Hist. Mus. (2009)10(4): 17-30 HUNTING BEHAVIOR OF THE ORIENTAL HORNET, Vespa orientalis L., AND DEFENSE BEHAVIOR OF THE HONEY BEE, Apis mellifera L., IN IRAQ Murtadha K. Glaiim Department of Plant Protection, College of Agriculture, Kerbala University, Karbala, Iraq E-mail: [email protected] ABSTRACT When the guard honey bees, Apis mellifera L., form a clump at the hive entrance or on the flight board, the oriental hornet, Vespa orientails L., either creeps toward the clump or hovers over it in order to take a bee. Once the hornet creeps, only few bees facing the hornet become alert, rock their heads and antennae, open their wings, and take a posture of defense. The rest of the clump stays listless without any signal of concern. However, the clump stays dense and the defending bees do not detach themselves neither from the rest of the clump nor from each other. For this reason, it is very difficult for the hornet to grab a bee unless the latter makes a “mistake” by detaching herself from other adjacent bees. If the hornet grabs such a bee, the other defending bees will not attack the hornet to free that bee even when the latter is one centimeter from the others. The defending bees can capture the hornet only when the latter grabs one of them which stands very close to the others. The hornet seems very “aware” of such a situation; hence she seldom becomes a captive. On the other hand, hovering over the clump makes it easier for the hornet to grab a bee.
