Primitive Angiosperm Flower – a Discussion*
Acta Bot. Neerl. 23(4), August 1974, p. 461-471. The structure and function of the primitive Angiosperm flower – a discussion* Gerhard Gottsberger Departamentode Botanica, Faculdade de Ciencias Medicas e Biologicas de Botucatu, Estado de Sao Paulo, Brazil SUMMARY Morphological and functional features of primitive entomophilous Angiosperm flowers are discussed and confronted with modem conceptions onearly Angiosperm differentiation. Evidence is put forward to show that large, solitary and terminally-borne flowers are not most primitive in the Angiosperms, but rather middle-sized ones, groupedinto lateral flower aggregates or inflorescences. It is believed that most primitive, still unspecialized Angiosperm flowers were pollinated casuallyby beetles. Only in a later phase did they graduallybecome adaptedto the more effective but more devastating type of beetle pollination. Together with this specialization, flower enlargment, reduction of inflorescences, numerical increase of stamens and carpels, and their more dense aggregationand flatteningmight have occurred. In have maintained the archaic condi- regard to pollination,many primitive Angiosperms tion of because beetles still dominant insect whereas in cantharophily, are a group, dispersal they have been largely forced to switch over from the archaic saurochory to the more modern modes of dispersal by birds and mammals,since duringthe later Mesozoic the dominance of reptiles had come to an end.

Efficacy of Entomopathogenic Nematodes and Entomopathogenic Fungi Against Masked Chafer White Grubs, Cyclocephala Spp

Youngman, Co-Chair Dr. Loke T. Kok, Co-Chair Dr. James M. Goatley Dr. Douglas G. Pfeiffer Dr. Sally L.

Under both laboratory and greenhouse conditions, additive interactions were found between EPN and EPF in their combined application against Cyclocephala spp., except a few observations that showed antagonism or synergism. Significantly greater control occurred from the combination of a nematode and a fungus compared with a fungus alone, but not compared with a nematode alone. The combined effect did not differ significantly for nematode and fungi applied simultaneously or at different times. EPF had no significant impact on EPN infection and production of infective juveniles (IJs) in grub carcasses. Nematodes alone or in combination with fungi were comparable to the insecticide Merit 75 WP (imidacloprid) against 3rd instar Cyclocephala spp in the greenhouse. -

Towards the Development of a Mycoinsecticide to Control White Grubs (Coleoptera: Scarabaeidae) in South African Sugarcane
Towards the development of a mycoinsecticide to control white grubs (Coleoptera: Scarabaeidae) in South African sugarcane A thesis submitted in fulfilment of the requirements for the degree of DOCTOR OF PHILOSOPHY IN SCIENCE of RHODES UNIVERSITY by Tarryn Anne Goble December 2012 ABSTRACT ABSTRACT In the KwaZulu-Natal (KZN) Midlands North region of South Africa, the importance and increased prevalence of endemic scarabaeids, particularly Hypopholis sommeri Burmeister and Schizonycha affinis Boheman (Coleoptera: Melolonthinae), as soil pests of sugarcane, and a need for their control was established. The development of a mycoinsecticide offers an environmentally friendly alternative to chemical insecticides. The identification of a diversity of white grub species, in two Scarabaeidae subfamilies, representing seven genera were collected in sugarcane as a pest complex. yH popholis sommeri and S. affinis were the most prevalent species. The increased seasonal abundances, diversity and highly aggregated nature of these scarabaeid species in summer months, suggested that targeting and control strategies for these pests should be considered in this season. Increased rainfall, relative humidity and soil temperatures were linked to the increased occurrence of scarab adults and neonate grubs. Beauveria brongniartii (Saccardo) Petch epizootics were recorded at two sites in the KZN Midlands North on H. sommeri. Seventeen different fluorescently-labelled microsatellite PCR primers were used to target 78 isolates of Beauveria sp. DNA. Microsatellite data resolved two distinct clusters of Beauveria isolates which represented the Beauveria bassiana senso stricto (Balsamo) Vuillemin and B. brongniartii species groups. These groupings were supported by two gene regions, the nucl ear ribosomal Internal Transcribed Spacer (ITS) and the nuc lear B locus (Bloc) gene of which 23 exemplar Beauveria isolates were represented and sequenced. -

La inmensa mayoría de las avispas bracónidos son parasitoides primarios de otros insectos holometábolos, razón por lo cual son utilizados en programas de control biológico de insectos plaga. Dada la importancia económica que poseen estas avispas, en el estado de Michoacán, a partir del año 2007 se realizan monitoreos constantes para conocer la fauna de avispas bracónidos que habitan en sus áreas forestales. Derivado de estos muestreos se detectó la presencia de cuatro especies del género Blacus, Blacus aulacis Van Achterberg, Blacus collaris (Ashmead), Blacus compressiventris Van Achterberg y Blacus cracentis Van Achterberg, que no habían sido reportados en el estado de Michoacán. El presente trabajo tiene como finalidad registrar por primera ocasión las cuatro especies del género encontradas en las áreas forestales Cerro de Garnica y Los Azufres, Michoacán. Palabras clave: avispas, bracónidos, parasitoides, áreas forestales, trampas amarillas. ABSTRACT. Most of the braconid wasps are primary parasitoids of other holometabolous insects, reason to be used in biological control programs for insect pests.
