Agriculture, Forestry and Fisheries . Vol. 9, No. 4, 2020, pp. 113-121. doi: 10.11648/j.aff.20200904.13 Received : June 5, 2020; Accepted : June 19, 2020; Published : July 28, 2020 Abstract: The experiment was conducted to evaluating the effects of fertilizer and harvesting age on agronomic performance, chemical composition and economic feasibility of Desho (Pennisetum Pedicellatum) grass under irrigation, in Ethiopia. A factorial arrangement with four fertilizer types (control, urea, compost and urea + compost), and three harvesting ages (90, 120 and 150) with three replications were used. Data on morphological characteristics of the grass were recorded. Based on the data collected, harvesting age was significantly affected the agronomic parameters of the grass. Plant height (PH), number of tillers per plant (NTPP), number of leaves per plant (NLPP), number of leaves per tiller (NLPT), dry matter yield (DMY), leaf length (LL) and leaf area (LA) were increased with increasing harvesting age, while leaf to stem ratio (LSR) showed a decreasing trend. -
Traits-Based and Perception Approaches for Management of Invasive Exotic Species from Tropical Botanic Gardens
TRAITS-BASED AND PERCEPTION APPROACHES FOR MANAGEMENT OF INVASIVE EXOTIC SPECIES FROM TROPICAL BOTANIC GARDENS DECKY INDRAWAN JUNAEDI Submitted in the total fulfillment of the requirements of the degree of Doctor of Philosophy June 2018 School of Biosciences University of Melbourne 1 Abstract ABSTRACT The factors driving plant invasion are key questions in invasion ecology. Traits also can act as indicators of plant invasion processes. If traits are proven to be a significant proxy for plant invasiveness, then invasiveness of exotic species may be efficiently predicted by measuring traits. Botanic gardens have consistently supported ex-situ plant conservation, research, and environmental education. However, botanic gardens can also be pathways of exotic invasive species introduction. Botanic gardens should become a strategic stakeholder for exotic invasive plant species management. For exotic invasive species management, we cannot solely rely on ecological approaches. Social perception is an important component of invasive species management. Social perception may become either a problem or a solution for invasive species management. These perceptions should be clarified among relevant stakeholders to minimize conflicts of interest among relevant stakeholders of invasive species management. This study focuses on invasive plant species in tropical environments and the aim of this study is to answer the following questions: (1) Focusing on the relationship between exotic species abundance and traits in the tropical ecosystem, what traits -
Homoptera: Psyllidae) in Hawaii
Vol. 31, December 31,1992 177 Taxonomic Status and Host Range of Three HeteropsyUa spp. (Homoptera: Psyllidae) in Hawaii WALTER T. NAGAMINE, BERNARR R. KUMASH1RO, and LARRY M. NAKAHARA1 ABSTRACT. The laxonomic status of two species of Hftrrvpsytla in Hawaii was clarified after confusion arose because of inadequate identification keys and the collection of mixed popu lations from a common host plant. A third species of llrtrmfisylla was also discovered for the first time in Hawaii (hiring January 1986. Most range tests were conducted with nine leguminous plants, lletemfisylla rubana Crawford, a senior synonym of //. inetia (Sulc), completed its development on leucaena (Ijnuarna UucocephaUt (l.am.) de Wit) and monkeypod (Samanea saman (Jacq.) Mem); //. huasachae Caldwell on koa (Acacia koa Gray), monkeypcxl, and slender mimosa (Desmanlhus virgatus (I.) Willd.); and //. fusca Crawford on klu {Acacia farnesiana (1..) Willcl.). Clarification of the taxonomic status of two HeteropsyUa spp. present in Hawaii was made recently. The close resemblance of the species within this genus, in addition to the collection of mixed populations from a common host plant, led to some early confusion. At that time, the need for revision of the HeteropsyUa group precluded their identifications. Later, with the revision work completed (Brown 1985, Burckhardt 1986, 1987) and with assistance of collaborators R. Brown and I. Hodkinson2, D. Burckhardt3, D. Hollis4, and D. Miller and L. Russell5, the determinations of two HeteropsyUa spp., H. cubana Crawford and H. huasachae Caldwell, were made. A third species, H. fusca Crawford, was later identified by I. Hodkinson, R. Brown, and D. Hollis. A summary of the three psyllids in Hawaii is presented below. -

A new species of the genus Tramaforda Manheim, 2007 (Hemiptera, Aphididae, Eriosomatinae, Fordini). Spixiana 43 (1): 93-104. Tramaforda wooli Manheim belongs to a monotypic genus that induces galls on Pistacia atlantica Desf. in Israel. Based on distinct gall characteristics, differences in morphometrics and molecular markers (CO I, CO II and microsatellite analysis), we recognized a new species in this genus, Tramaforda koachi sp. nov. which is cur- rently endemic to north-central Israel and the Golan Heights. Fall migrants of Tramaforda koachi sp. nov. are smaller (1.62-2.02 mm) than the same form of T. wooli (> 2.14 mm). However, no distinct qualitative morphological differences were found between fall migrants of these two species.

Identification of Invasive Alien Species Using DNA Barcodes
Identification of Invasive Alien Species using DNA barcodes Royal Belgian Institute of Natural Sciences Royal Museum for Central Africa Rue Vautier 29, Leuvensesteenweg 13, 1000 Brussels , Belgium 3080 Tervuren, Belgium +32 (0)2 627 41 23 +32 (0)2 769 58 54 General introduction to this factsheet The Barcoding Facility for Organisms and Tissues of Policy Concern (BopCo) aims at developing an expertise forum to facilitate the identification of biological samples of policy concern in Belgium and Europe. The project represents part of the Belgian federal contribution to the European Research Infrastructure Consortium LifeWatch. Non-native species which are being introduced into Europe, whether by accident or deliberately, can be of policy concern since some of them can reproduce and disperse rapidly in a new territory, establish viable populations and even outcompete native species. As a consequence of their presence, natural and managed ecosystems can be disrupted, crops and livestock affected, and vector-borne diseases or parasites might be introduced, impacting human health and socio-economic activities. Non-native species causing such adverse effects are called Invasive Alien Species (IAS). In order to protect native biodiversity and ecosystems, and to mitigate the potential impact on human health and socio-economic activities, the issue of IAS is tackled in Europe by EU Regulation 1143/2014 of the European Parliament and Council. The IAS Regulation provides for a set of measures to be taken across all member states. The list of Invasive Alien Species of Union Concern is regularly updated. In order to implement the proposed actions, however, methods for accurate species identification are required when suspicious biological material is encountered.
