“…From data presented in this study it was clear that protein content in the haemolymph of drones was higher in those of Alexandria than those of Giza .The difference might be due to the presence of certain factors influencing the rearing and maturing of drones . These results agreed with those of Parker(1971).He reported that the low content of haemolymph proteins in newly emerged drones might be attributed to no feeding during pupation .He also found that feeding of the newly emerged adults helped to raise the haemolymph protein content. Also, this difference might have been caused by the supply of pollen by nurse bees in colony .…”

The present work aimed to study the effect of incubation type on protein contents of the ovaries of queens (different ages) and effect of locality on protein contents in drone stages . Protein contents of newly emerged queens (0-day old) which incubated in an incubator ( artificial incubation )were higher than in those incubated in a colony (natural incubation ), and decreased with age . But queens which kept in a colony, the protein contents increased according to queen age . Also , there were significant differences between protein content in the haemolymph of mature drones produced in two localities Giza and Alexandria . This difference might have been caused by the supply of pollen by nurse bee in the colony .

“…Because of the high toxin concentration in the “pupa” compared to that in the adult, De la Harpe et al (1983) suggested that diamphotoxin must have some functional role in this life stage, but it was unclear how autolysis was prevented. Diamphotoxin protein may be similar to toxic insect proteins found in tiger moths (Rothschild et al 1970; Hsiao et al 1980) and to leptinotarsin from the beetle, Leptinotarsa Chevrolat (Hsiao and Fraenkel 1969; Snyder 1971; Parker 1971, 1972; Satin et al 1978; Hsiao 1978; McClure et al 1980; Madeddu et al 1985a, b; Miljanich et al 1988). Leptinotarsa (subfamily Chrysomelinae) is phylogenetically distantly related to the galerucine Blepharida -group.…”

The use of archery to hunt appears relatively late in human history. It is poorly understood but the application of poisons to arrows to increase lethality must have occurred shortly after developing bow hunting methods; these early multi-stage transitions represent cognitive shifts in human evolution. This paper is a synthesis of widely-scattered literature in anthropology, entomology, and chemistry, dealing with San (“Bushmen”) arrow poisons. The term San (or Khoisan) covers many indigenous groups using so-called ‘click languages’ in southern Africa. Beetles are used for arrow poison by at least eight San groups and one non-San group. Fieldwork and interviews with Ju|’hoan and Hai||om hunters in Namibia revealed major differences in the nature and preparation of arrow poisons, bow and arrow construction, and poison antidote. Ju|’hoan hunters use leaf-beetle larvae of Diamphidia Gerstaecker and Polyclada Chevrolat (Chrysomelidae: Galerucinae: Alticini) collected from soil around the host plants Commiphora africana (A. Rich.) Engl. and Commiphora angolensis Engl. (Burseracaeae). In the Nyae Nyae area of Namibia, Ju|’hoan hunters use larvae of Diamphidia nigroornata Ståhl. Larvae and adults live above-ground on the plants and eat leaves, but the San collect the underground cocoons to extract the mature larvae. Larval hemolymph is mixed with saliva and applied to arrows. Hai||om hunters boil the milky plant sap of Adenium bohemianum Schinz (Apocynaceae) to reduce it to a thick paste that is applied to their arrows. The socio-cultural, historical, and ecological contexts of the various San groups may determine differences in the sources and preparation of poisons, bow and arrow technology, hunting behaviors, poison potency, and perhaps antidotes.

INFLUENCE DES NÉMATODES PARASITESsur l'hémolymphe des adultes d' 'Ips sexdentatus Boern.(COLEOPTERA : SCOLYTIDAE)RÉSUMÉ. Les modifications provoquées par les nématodes parasites sur le volume des prélève ments d'hémolymphe et la teneur en protéines et en acides aminés hémolymphatiques chez Ips sexdentatus sont suivies pendant la maturation de préessaimage et la préparation de la ponte des insectes, jusqu'au dépôt du premier oeuf. Le volume d'hémolymphe recueilli chez les insectes parasités est apparemment peu afïecté par les nématodes. Les Parasitaphelenchus provoquent une nette diminution de la concentration en acides aminés, mais la concentration protéique n'est que peu modifiée. L'hypothèse d'une action spolia trice directe des Parasitaphelenchus sur l'un ou l'autre des deux types de composés est avancée. Dans le cas d'un parasitisme par Contortylenchus diplogaster, la teneur en acides aminés et en protéines hémolymphatiques est fortement augmentée, sauf chez les insectes en essaimage et les femelles en maturation de ponte. Ces résultats sont expliqués en faisant intervenir une stimulation de la synthèse et de la sécrétion protéique par le tissu adipeux d sexdentatus sous l'action de la femelle parasite de C. diplogaster ; cette stimulation serait accompagnée d'une dégradation des protéines synthétisées. Influence of the parasitic Nematodes on the hemolymph of Ips sexdentatusBoern (Coleoptera : Scolytidae)SUMMARY. The changes produced by parasitic nematodes in the volume of the hemolymph collected and the hemolymph protein and amino acid level in Ips sexdentatus are observed through out pre-swarming maturation and ovarian maturation until the first oviposition. The volume of the hemolymph collected in infected insects is apparently little affected by the nematodes. Parasitaphelenchus induce a marked decrease in amino acid concentration, but the protein concentration remains little modified. The hypothesis that Parasitaphelenchus exert a direct spoliatory action on any of the two types of compounds is suggested. In the case of infection by Contortylenchus diplogaster the hemolymph protein and amino acid concentration increases significantly except in the swarming insects and females during ovarian maturation. These findings can be accounted for by a stimulation of the protein synthesis and secretion by the fat body of Ips sexdentatus under the influence of the parasitic female of C. diplogaster. This stimu lation would be accompanied by a degradation of the synthesized proteins.
