ANALYSIS OF THE DAMAGE CAUSED BY THE BLACK BEAN APHID ( APHIS FABAE SCOP.) TO FIELD BEANS ( VICIA FABA L.) BY JESUS ANTONIO SALAZAR, ING. AGR. ( VENEZUELA ) A THESIS SUBMITTED FOR THE DEGREE OF DOCTOR OF PHILOSOPHY IN THE UNIVERSITY OF LONDON OCTOBER 1976 IMPERIAL COLLEGE FIELD STATION, SILWOOD PARK, SUNNINGHILL, ASCOT, BERKSHIRE. 2 ABSTRACT The concept of the economic threshold and its importance in pest management programmes is analysed in Chapter I. The significance of plant responses or compensation in the insect-injury-yield relationship is also discussed. The amount of damage in terms of yield loss that results from aphid attack, is analysed by comparing the different components of yield in infested and uninfested plants. In the former, plants were infested at different stages of plant development. The results showed that seed weights, pod numbers and seed numbers in plants infested before the flowering period were significantly less than in plants infested during or after the period of flower setting. The growth pattern and growth analysis in infested and uninfested plants have shown that the rate of leaf production and dry matter production were also more affected when the infestations occurred at early stages of plant development. When field beans were infested during the flowering period and afterwards, the aphid feeding did not affect the rate of leaf and dry matter production. There is some evidence that the rate of leaf area production may increase following moderate aphid attack during this period. The relationship between timing of aphid migration from the wintering host and the stage of plant development are shown to be of considerable significance in determining the economic threshold for A.

Edge-Biased Distributions of Insects. a Review
Agronomy for Sustainable Development (2018) 38: 11 https://doi.org/10.1007/s13593-018-0488-4 REVIEW ARTICLE Edge-biased distributions of insects. A review Hoang Danh Derrick Nguyen1 & Christian Nansen 1,2 Accepted: 15 January 2018 /Published online: 5 February 2018 # The Author(s) 2018. This article is an open access publication Abstract Spatial ecology includes research into factors responsible for observed distribution patterns of organisms. Moreover, the spatial distribution of an animal at a given spatial scale and in a given landscape may provide valuable insight into its host preference, fitness, evolutionary adaptation potential, and response to resource limitations. In agro-ecology, in-depth understanding of spatial distributions of insects is of particular importance when the goals are to (1) promote establishment and persistence of certain food webs, (2) maximize performance of pollinators and natural enemies, and (3) develop precision-targeted monitoring and detection of emerging outbreaks of herbivorous pests. In this article, we review and discuss a spatial phenomenon that is widespread among insect species across agricultural systems and across spatial scales—they tend to show “edge-biased distributions” (spatial distribution patterns show distinct “edge effects”). In the conservation and biodiversity literature, this phenomenon has been studied and reviewed intensively in the context of how landscape fragmentation affects species diversity. However, possible explanations of, and also implications of, edge-biased distributions of insects in agricultural systems have not received the same attention. Our review suggests that (1) mathe- matical modeling approaches can partially explain edge-biased distributions and (2) abiotic factors, crop vegetation traits, and environmental parameters are factors that are likely responsible for this phenomenon.

Guide to the Euonymus of New York City
New York City EcoFlora Guide to the Euonymus (Euonymus) of New York City Euonymus is a genus of 130–140 species in the mostly tropical Celastraceae (Staff-Tree) family. The family comprises about 95 genera and 1,350 species. Only three genera occur in the northern hemisphere, Euonymus, Celastrus and Parnassia, all three found or once found in New York City. Euonymus species occur nearly worldwide with most species native to eastern Asia. They are trees, shrubs or woody vines, the stems often angled or winged, sometimes climbing by adventitious roots; leaves deciduous or evergreen, opposite, the blades simple, margins crenate or toothed; inflorescences terminal or axillary; flowers in small clusters, petals usually green, sometimes white or purple; fruit usually brightly colored, lobed capsules; seeds enveloped in brightly colored tissue (aril), often contrasting with the fruit wall. Euonymus (as well as most members of the Celastraceae family) can often be recognized by “gestalt”. The leaves and often the stems too have a distinctive, but somewhat variable yellow-green color that is hard to describe but nearly unlike any other plants. The leaves are usually leathery, and almost always have distinctively scalloped (crenate) margins (the margins rarely completely smooth or toothed). There are four species native to North America, one species endemic to California, Oregon and Washington (Euonymus occidentalis); a predominately Midwestern species (Euonymus obovatus); a widespread northeastern species (Euonymus atropurpureus) and a widespread southeastern species (Euonymus americanus). Two species are indigenous to New York City. The predominately southeastern US species, Euonymus americanus, American Strawberry Bush is endangered in New York State.

Comparison of Different Classifications on the Celastraceae
UNITED STATES DEPARTMENT OF AGRICLJLTURE AGRICULTURAL RESEARCH SERVICE NORTHEASTERN REGlON AGRICULTURAL RESEARCH CENTER BELTSVILLE. MARYLAND 20705 Novenber 7, 1974 / Subject: ConpadSon of Different Classifications on the Celastraceae in Africa with Discussions on the Status of Gymnosporia and Other Genera To : R. E. Perdue, Jr., Chief ,.. Medicinal Plant Resources ~aboratory Currently, the taxonomy of the Celastraceae is in a state of confusion. A few recent revisions limited mostly ,to political boundaries, have helped to clarify the systematics in a few genera; however, the continued disagreement among generic relationships seems to make it nore difficult for the non-specialist. Because of special efforts to procure plant samples in this family, frequent synonomy has led to confusion as well as duplica- tion, especially in Africa where a number of samples have been received from floristically related countries in which different authorities are recogcized for the Celastracean Flora. This report, primarily, will 'deal with the systematic problems of the African Celasrrtseae. Until recently, the Hippocrateaceae was treated as a separate family from the Celastraceae (Smith, 1940; Loesener, 1942; Wilczek, 1960; Hallee, 1962). L Robson (1965, 1966), Ding Hou (1963, 1964), Blakelock (1958), and Codd (1972) have united the Hippocrateaceae with the Celastraceae; but, their reasons for uniting the two families are not in agreement. The Celastraceae is believed by Codd and Kobson to comprise about 60 to 70 genera, but Ding Hou has indicated that there are about 90 genera. For the purpose of identifying two major complexes, which taxonomists are not in agreement, I will refer to the Celastraceae and Hippocrateaceae as two separate families.
