  1. The importance of certain insects as pollinators of sunflower (<em>Helianthus annuus</em> L.)

    The importance of certain insects as pollinators of sunflower (<em>Helianthus annuus</em> L.)

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    This study reports the effects of Apis mellifera L. (honeybees), Astylus atromaculatus Blanchard (spotted maize beetles), Heliothis armigera Hübner (American bollworm larvae) and Musca domestica L. (house flies) on seed set in commercial sunflower. The pollination efficiency of these insects...
  2. Laboratory assay to determine efficacy of insecticides for control of the spotted maize beetle, <em>Astylus atromaculatus</em> Blanchard (Coleoptera: Melyridae), a pest of sorghum

    Laboratory assay to determine efficacy of insecticides for control of the spotted maize beetle, <em>Astylus atromaculatus</em> Blanchard (Coleoptera: Melyridae), a pest of sorghum

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Spotted maize beetle, (Astylus atromaculatus), African boll- worm, (Helicoverpa armigera) and various aphid species attack sorghum from flowering onwards. The possibility of simultaneous control of these pests with a single application of an insecticide exists. The efficacy of insecticides registered...
  3. Reproductive biology of <em>Corymbia citriodora</em> subsp. <em>variegata</em> and effective pollination across its native range in Queensland, Australia

    Reproductive biology of <em>Corymbia citriodora</em> subsp. <em>variegata</em> and effective pollination across its native range in Queensland, Australia

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    The spotted gum species complex represents a group of four eucalypt hardwood taxa that have a native range that spans the east coast of Australia, with a morphological cline from Victoria to northern Queensland. Of this group, Corymbia citriodora subsp...
  4. Genetic variation in growth and wood-quality traits of <em>Corymbia citriodora</em> subsp. <em>variegata</em> across three sites in south-east Queensland, Australia

    Genetic variation in growth and wood-quality traits of <em>Corymbia citriodora</em> subsp. <em>variegata</em> across three sites in south-east Queensland, Australia

    Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science
    Ten growth or wood-quality traits were assessed in three nearby Corymbia citriodora subsp. variegata (CCV) open-pollinated family-within-provenance trials (18 provenances represented by a total of 374 families) to provide information for the development of a breeding program targeting both pulp...
  5. Estimation of taper rates and volume of smaller-sized logs in spotted gum saw timber plantations in Southeast Queensland, Australia

    Item type: Journal Article • Journal: Southern Hemisphere Forestry Journal
    Spotted gum (Corymbia citriodora subsp. variegata) is a popular tree species for hardwood saw timber plantations in Southeast Queensland (SEQ), Australia. In many parts of the world, logs up to 10cm top diameter are considered to be merchantable logs and...
  6. Estuarine and coastal connectivity of an estuarine-dependent fishery species, <em>Pomadasys commersonnii</em> (Haemulidae)

    Estuarine and coastal connectivity of an estuarine-dependent fishery species, <em>Pomadasys commersonnii</em> (Haemulidae)

    Item type: Journal Article • Journal: African Journal of Marine Science
    Understanding the level of connectivity between estuarine and coastal waters is essential for appropriate management of estuarine-associated taxa. Most studies have focused on the role of a single estuary, while limited research exists on the importance of multiple estuaries to...
