DISTRIBUTION AND SEASONAL ABUNDANCE OF THE FLOWERBUD WEEVIL ANTHONOMUS SANTACRUZI HUSTACHE (COLEOPTERA: CURCULIONIDAE) IN KWAZULU-NATAL AND ITS IMPACT ON THE INVASIVE WEED SOLANUM MAURITIANUM SCOPOLI (SOLANACEAE) Kelby Farrell English Submitted in fulfilment of the academic requirements for the degree of Master of Science in the Discipline of Entomology School of Life Sciences College of Agriculture, Engineering and Science University of KwaZulu-Natal Pietermaritzburg 2016 PREFACE The research described in this dissertation was carried out in the School of Life Sciences (Pietermaritzburg campus) from February 2014 to February 2016 under the supervision of Dr T.

Signed: ___________________________ Kelby Farrell English (Candidate) ___________________________ Dr Terence Olckers (Supervisor) i ABSTRACT Solanum mauritianum Scopoli (Solanaceae), native to South America, is an invasive weed of tropical, subtropical and warm temperate regions in many countries including South Africa. The seed-packed fruits are highly palatable to native birds which feed on them throughout the year, vastly aiding in the weed’s dispersal. Research into the biological control of the weed began in the 1980s after chemical and mechanical control efforts proved insufficient and resulted in the release of Gargaphia decoris Drake (Hemiptera: Tingidae), a leaf-sucking lace bug, in 1999. Anthonomus santacruzi Hustache (Coleoptera: Curculionidae), a flowerbud weevil, was later released in 2008 to reduce the excessive levels of fruiting by S.

Solanum Mauritianum (Woolly Nightshade)
ERMA New Zealand Evaluation and Review Report Application for approval to import for release of any New Organisms under section 34(1)(a) of the Hazardous Substances and New Organisms Act 1996 Application for approval to import for release Gargaphia decoris (Hemiptera, Tingidae), for the biological control of Solanum mauritianum (woolly nightshade). Application NOR08003 Prepared for the Environmental Risk Management Authority Summary This application is for the import and release of Gargaphia decoris (lace bug) for use as a biological control agent for the control of Solanum mauritianum (woolly nightshade). Woolly nightshade is a rapid growing small (10m) tree that grows in agricultural, coastal and forest areas. It flowers year round, and produces high numbers of seeds that are able to survive for long periods before germinating. It forms dense stands that inhibit the growth of other species through overcrowding, shading and production of inhibitory substances. It is an unwanted organism and is listed on the National Pest Plant Accord. The woolly nightshade lace bug (lace bug) is native to South America, and was introduced to South Africa as a biological control agent for woolly nightshade in 1995. Success of the control programme in South Africa has been limited to date. The lace bug has been selected as a biological control agent because of its high fecundity, high feeding rates, gregarious behaviours and preference for the target plant. Host range testing has indicated that the lace bug has a physiological host range limited to species within the genus Solanum, and that in choice tests woolly nightshade is the preferred host by a significant margin.

ECOLOGICAL FACTORS AFFECTING THE ESTABLISHMENT OF THE BIOLOGICAL CONTROL AGENT Gargaphia decoris DRAKE (HEMIPTERA: TINGIDAE) A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Plant Science at Massey University, Manawatu, New Zealand Cecilia María Falla 2017 ABSTRACT The Brazilian lace bug (Gargaphia decoris Drake (Hemiptera:Tingidae)) was released in New Zealand in 2010 for the biological control of the invasive weed woolly nightshade (Solanum mauritianum Scopoli (Solanaceae)). Currently there is scarce information about the potential effect of ecological factors on the establishment of this biological control agent. This study investigated: 1) the effect of maternal care and aggregation on nymphal survival and development; 2) the effect of temperature, photoperiod and humidity on G. decoris performance; and 3) the effect of light intensity on S. mauritianum and G. decoris performance. Maternal care and aggregation are characteristic behaviours of G. decoris. These behaviours have an adaptive significance for the offspring and are key determinants for the survival of the species under natural conditions. Maternal care is reported to increase the survival and development of offspring under field conditions, and higher aggregations to increase the survival of the offspring. However, in this study, maternal care negatively affected the survival and development of the offspring, and higher aggregations had no significant impact on offspring survival.

Research on Plants with Medicinal Properties in Suriname Dennis R.A
Clinical and Medical Investigations Review Article ISSN: 2398-5763 “Nature, green in leaf and stem”. Research on plants with medicinal properties in Suriname Dennis R.A. Mans* Department of Pharmacology, Faculty of Medical Sciences, Anton de Kom University of Suriname, USA Abstract The widely held layman’s perception of nature as a collection of animals operating against a static green background of plants is a serious misunderstanding of the complexity and dynamics of the plant biodiversity. Plants fulfill all functions that superficially only seem reserved for animals including movement, communication, and defense. For the latter purposes, plants have developed intricate and highly sophisticated chemical warning signals and defense systems to alarm friends and ward off foes. Many of these plant substances possess meaningful pharmacological properties, and some were found useful against human diseases. This paper briefly describes several aspects of plant communication and defense; gives a few examples of plant-derived therapeutics; and focuses on the potential contribution of Suriname (South America) to this scientific area. Background organs of the plant and transport seeds away from the parent plant, enabling its propagation and the colonization of new niches, receiving The view of the plant kingdom as a green and static background valuable sources of food in return [7]. for moving animals - particularly (higher) vertebrates - is far from the reality. Paraphrasing Alfred, Lord Tennyson’s (1809-1892) words “Tho’ Other means of plant communication are so-called semiochemicals, nature, red in tooth and claw” in his poem ‘In Memoriam A.H.H.’, plant substances involved in the transfer of information between plants the American author, physician, producer, director, and screenwriter and other organisms [8].

(Solanaceae) is one of the largest genera of angiosperms and presents difficulties in identifica- tion due to lack of regional keys to all groups. Here we provide keys to all 135 species of Solanum native and naturalised in Africa (as defined by World Geographical Scheme for Recording Plant Distributions): continental Africa, Madagascar (incl. the Indian Ocean islands of Mauritius, La Réunion, the Comoros and the Seychelles), Macaronesia and the Cape Verde Islands. Some of these have previously been pub- lished in the context of monographic works, but here we include all taxa.

Biological Control of Solanum Mauritianum: South African Experiences and Prospects for the Pacific Islands
Session 5 Prospects for Weed Biological Control in Pacific Islands 249 Biological Control of Solanum mauritianum: South African Experiences and Prospects for the Pacific Islands T. Olckers School of Biological & Conservation Sciences, University of KwaZulu-Natal, Private Bag X01, Scottsville 3209, South Africa [email protected] Abstract Solanum mauritianum Scop. (Solanaceae), a fast-growing tree with a high seed output, threatens commercial activities and natural habitats in several tropical, subtropical and warm temperate regions worldwide. The plant’s high reproductive output, long-distance seed dispersal by birds and short-lived seed banks, suggest that it is an appropriate target for biological control using agents that can reduce its rapid growth rates and high levels of fruiting. South Africa was the first country to explore this possibility and has pursued it for 26 years. The program was recently extended to New Zealand, and several other countries (e.g., Pacific Islands) also may be able to benefit from South African experiences. Although surveys in South America have revealed several promising candidate agents, there have been major difficulties in securing their release because of the conservative nature of host-specificity testing and several cultivated and native plant species in the genus Solanum. Despite these hurdles, two agents have been released and established in South Africa and are now pending release in New Zealand. Guidelines for countries wishing to target S. mauritianum for biological control include: (i) conducting
