Generating Compact Wasp Nest Structures via Minimal Complexity Algorithms.
… Three rules postulated to be functions of wasps' building behavior were developed. First is the random rule, in which there is no constraint per the choice of site to be initiated. The second is the 2-cell rule where only sites with at least two ready walls are initiated. Third, the maxWall …

Cooperation And Competition In Paper Wasp And Human Societies
… colonies. I focus on the primitively eusocial wasp Polistes dominulus, as individuals display behavioral flexibility and benefit from investing in both cooperation and conflict. In chapter 3, I use field and lab experiments test theoretical predictions that P. dominulus may not face a simple …

Why do wasp induced galls of Acacia longifolia photosynthesise?
… capacity of bud galls induced by the wasp, Trichilogaster acaciae longifoliae (Pteromalidae) in the invasive Acacia longifolia. The role of this photosynthetic activity was examined in terms of its ability to subsidise carbon budgets, as well as to provide O₂ to the larvae and consume …

Regulation of WASP in Actin Signaling: From Angstroms to Microns
Wiskott-Aldrich syndrome protein (WASP) regulates membrane-attached force generation by promoting actin polymerization, which is key to cell motility and immune responses. Mutations in WASP lead to Wiskott-Aldrich syndrome and neutropenia. My graduate research was focused on allosteric regulation …

Identification of genes from the poxvirus of a parasitoid wasp
… poison gland apparatus of a female parasitoid wasp, D. longicaudata. The wasp apparently injects DlEPV into host fly larvae along with the egg during oviposition. Although the effect of the presence of DlEPV on wasp larvae survival within the host is unknown, the virus does appear to disrupt …

Processive Acceleration of Actin Barbed End Assembly by N-WASP
… Neural Wiskott Aldrich syndrome protein (N-WASP) is involved in transduction of signals from receptors on the cell surface to the actin cytoskeleton. N-WASP activated actin polymerization drives extension of invadopodia and podosomes into the basement layer. In addition to activating Arp2/3 …

Transcriptional responses of Eucalyptus clones to the gall wasp, Leptocybe invasa
… is an Australian gall-inducing wasp that oviposits along immature midribs, petioles and stems. The larvae are endophytic herbivores that cause the development of coalescing galls (abnormal plant growths) and lead to a wide range of symptoms such as stunted growth, die-back and …

Patterns of association in a co-introduced insect herbivore and parasitoid wasp
Species within trophic networks that experience a range expansion can lead to populations of coevolved species re-associating in some areas, not associating in others, or creating novel associations with native species at one or more trophic level(s). Although most studies have focused …

The effects of urbanisation on bee and wasp communities in Cape Town, South Africa
Bees and wasps provide essential regulatory ecosystem services by pollinating urban plants. However, there are massive global declines in many insect groups, and little is known about the impacts of urbanisation on pollinators in rapidly developing areas of Africa. South Africa is one of the most …

Structural and biochemical insight into the interactions of Cdc42 with TOCA1 and N-WASP
… proteins of the Wiskott-Aldrich Syndrome (WASP) family and the Transducer of Cdc42-dependent Actin assembly (TOCA) family. The WASP family and their activation by Cdc42 have been thoroughly studied in vitro and are well understood. Conversely, understanding of the TOCA family remains …

The Effects of Wildfire Burn Severity on Bee and Wasp Communities Two Decades Post-Fire
… Disturbances like wildfire affect bee and wasp communities, but recent meta-analyses are conflicted about whether fire harms or benefits insect pollinators. We investigated the lasting effects of wildfire burn severity on wild bee communities and floral resource availability across …

"Molecular Analysis of Virulence Factors Unique to Leptopilina heterotoma-a Parasitic Wasp of Drosophila spp."
<p>Endoparasitioid wasps of Drosophila spp. frequently avoid or overcome the immune defense mechanisms of their fly hosts. Leptopilina heterotoma (Lh) is a generalist wasp species, successful on many Drosophila spp. world-wide. During oviposition, the female wasp introduces venom proteins and …

Hypersensitive Response in Live Oak: Characterization and Efficacy Against a Host of Specific Gall-Forming Wasp
… to oviposition by the host specific gall-forming wasp Belonocnema treatae to assess whether apparent HR functions in plateau live oak as a plant defense, and if so, to estimate its importance. To do this I examined the probability of gall establishment in the presence and absence of necrosis …
