    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.

  • (Pentatomidae) DISSERTATION Presented
    Genome Evolution During Development of Symbiosis in Extracellular Mutualists of Stink Bugs (Pentatomidae) DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Alejandro Otero-Bravo Graduate Program in Evolution, Ecology and Organismal Biology The Ohio State University 2020 Dissertation Committee: Zakee L. Sabree, Advisor Rachelle Adams Norman Johnson Laura Kubatko Copyrighted by Alejandro Otero-Bravo 2020 Abstract Nutritional symbioses between bacteria and insects are prevalent, diverse, and have allowed insects to expand their feeding strategies and niches. It has been well characterized that long-term insect-bacterial mutualisms cause genome reduction resulting in extremely small genomes, some even approaching sizes more similar to organelles than bacteria. While several symbioses have been described, each provides a limited view of a single or few stages of the process of reduction and the minority of these are of extracellular symbionts. This dissertation aims to address the knowledge gap in the genome evolution of extracellular insect symbionts using the stink bug – Pantoea system. Specifically, how do these symbionts genomes evolve and differ from their free- living or intracellular counterparts? In the introduction, we review the literature on extracellular symbionts of stink bugs and explore the characteristics of this system that make it valuable for the study of symbiosis. We find that stink bug symbiont genomes are very valuable for the study of genome evolution due not only to their biphasic lifestyle, but also to the degree of coevolution with their hosts. i In Chapter 1 we investigate one of the traits associated with genome reduction, high mutation rates, for Candidatus ‘Pantoea carbekii’ the symbiont of the economically important pest insect Halyomorpha halys, the brown marmorated stink bug, and evaluate its potential for elucidating host distribution, an analysis which has been successfully used with other intracellular symbionts.

Acquisition and inoculation of Xf occur sometime during the process of stylet penetration into the plant. That process is most rigorously studied via electrical penetration graph (EPG) monitoring of insect feeding. This study provides part of the crucial biological meanings that define the waveforms of each new insect species recorded by EPG. By synchronizing AC EPG waveforms with high-magnification video of H. coagulata stylet penetration in artifical diet, we correlated stylet activities with three previously described EPG pathway waveforms, A1, B1 and B2, as well as one ingestion waveform, C. Waveform A1 occured at the beginning of stylet penetration. This waveform was correlated with salivary sheath trunk formation, repetitive stylet movements involving retraction of both maxillary stylets and one mandibular stylet, extension of the stylet fascicle, and the fluttering-like movements of the maxillary stylet tips.

  • Alfalfa Aphid and Leafhopper Management for the Low Deserts
    ALFALFA APHID AND LEAFHOPPER MANAGEMENT FOR THE LOW DESERTS Eric T. Natwick U.C. Cooperative Extension Farm Advisor, Imperial County, California APHIDS Spotted Alfalfa ~ The spotted alfalfa aphid (Therioaphis maculata) was introduced into New Mexico in 1953 and by 1954 had spread westward into California. This aphid is small pale yellow or grayish in color with 4 to 6 rows of black spots bearing small spines on its back. The adults mayor may not have wings. Spotted alfalfa aphid is smaller than blue alfalfa aphid or pea aphid arid will readily drop from plants when disturbed. The aphids are common on the underside of leaves where colonies start on the lower part of the plants, but also infest stems and leaves ~s colonies expand. These aphids produce great Quantities of honeydew. Severe infestations can develop on non-resistant varieties of alfalfa and reduce yield, stunt growth and even kill plants. Feed Quality and palatability are also reduced by sooty molds which grow on the honeydew excrement. In most desert growing areas introduction of resistant varieties (e.g., CUF101) along with the activity of predacious bugs, lady beetles, lacewings, syrphid fly larvae and introduced parasites has reduced this aphid to the status of a minor pest. If susceptible varieties are planted and beneficial insect populations are disrupted, then severe infestations can occur from late July through September. Because spotted alfalfa aphid has developed resistance to organophosphorus compounds, the best way to avoid aphid problems is the planting of a resistant variety. In fields where a susceptible variety is planted the field should be checked 2 to 3 times per week during July through September.

  • Aphids and Their Control on Orchids
    APHIDS AND THEIR CONTROL ON ORCHIDS Paul J. Johnson, Ph.D. Insect Research Collection, South Dakota State University, Brookings, SD 57007 Aphids are among the most obnoxious of orchid pests. These insects are global and orchid feeding species are problematic in tropical growing areas as well as in commercial and hobby greenhouses in temperate regions. Rabasse and Wyatt (1985) ranked aphids as one of three most serious greenhouse pests, along with spider mites and whiteflies. These pernicious insects can show themselves on orchids year-around in warm climates, but seem to be mostly autumn and winter problems in temperate regions. Like most other orchid pests the most common routes into plant collections is through either the acquisition of an infested plant or the movement of plants from outdoors to indoors. However, certain reproductive stages of pest species do fly and they will move to orchids from other plants quite readily. Because of their propensity for rapid reproduction any action against aphids should be completed quickly while their populations are still small. An aphid infestation is often detected by an accumulation of pale-tan colored “skins” that fall beneath the developing colony. These “skins” are the shed integument from the growing and molting immature aphids. All of the common pest species of aphid also secrete honeydew, a feeding by-product exuded by the aphid and composed of concentrated plant fluids, and is rich in carbohydrates. This honeydew drips and accumulates beneath the aphid colony. Because of the carbohydrates honeydew is attractive to ants, flies, bees, other insects including beneficial species, and sooty mold.

Biota Neotropica 20(4): e20201045. https://doi.org/10.1590/1676-0611-BN-2020-1045 Abstract: Pentatomidae comprises a diverse group of stink bugs widely distributed in the Neotropical region. Many species are phytophagous and cause injuries to plants, and can thus be defined as agricultural pests. In this study, the anatomy of the female and male reproductive tracts of three important agricultural pests in Colombia is described: Piezodorus guildinii Westwood, 1837 and Chinavia ubica Rolston 1983, found on soybeans, and Oebalus insularis Stål, 1872, found in rice crops. For that, light microscopy techniques were used. The anatomy of the reproductive tract of sexually mature males of the three species studied consisted of a pair of testes, vas deferens, seminal vesicles, ejaculatory bulb, an ejaculatory duct that opens into an aedeagus, and paired accessory glands.

  • Aphid and Whitefly Management in Alfalfa in Imperial Valley, California
    APHID AND WHITEFLY MANAGEMENT IN ALFALFA IN IMPERIAL VALLEY, CALIFORNIA Eric T. Natwick and M. Lopez1 ABSTRACT In the low desert region of southern California and Arizona, spotted alfalfa aphid, Therioaphis maculata, pea aphid, Acyrthosiphon pisum, blue alfalfa aphid, Acyrthosiphon kondoi, and cowpea aphid, Aphis craccivora must be managed for successful alfalfa hay production. Considerable progress has been made toward the control of the aphid pests via host plant resistance, but insecticide applications are commonly needed to maintain population densities of aphids below damaging levels. Experiments were conducted at the University of California Desert Research and Extension Center in 1999, 2000 and 2004 to compare efficacy of registered and unregistered materials and combinations of materials for aphid control in alfalfa. The results of these three insecticide efficacy experiments indicate that cowpea aphid is susceptible to control by several different aphicides. Currently there are no cowpea aphid resistant alfalfa varieties. Therefore, cowpea aphid should be controlled using an insecticide registered for use on alfalfa when a damaging population builds up in an alfalfa stand. INTRODUCTION Although several resistant varieties have been developed and released, resistance levels have been low and variable (Lehman 1978). Insecticides still have a major role in the alfalfa insect pest management (Natwick 1987). The blue alfalfa aphid, cowpea aphid, pea aphid and spotted alfalfa aphid are commonly controlled in low desert alfalfa with chlorpyrifos or dimethoate when aphid populations reach damaging levels (Anonymous 2003, Anonymous 1985). Other insecticides used in alfalfa that provide aphid control include: carbofuran, several pyrethroid insecticides or malathion. Insecticides are applied to a large portion of the alfalfa acreage in the low desert region of the Southwestern United States each year for aphid control.

SAINI*** ABSTRACT - Two species of leafhoppers and four species of cereal aphids appear to be trans­ ported to Minnesota each spring on strong winds from the south or southwest. The aster leaf­ hopper, Macrosle/es fascifrons (Stall; the English grain aphid, Macrosiphum avenae (Fabr.l; the apple grain aphid, Rhopalosiphum fitchii (Sand.); and the greenbug, Schizaphis graminum (Rend.), usually arrive in Minnesota during late April or early May. Weather conditions favor­ able for northward movement of these insects consist of a high pressure area over the eastern states, a low pressure area over the western plains, and the resulting strong, persistent, south wind which is often called a low-level jet.

  • Cotton—Aphid and Whitefly Monitoring
    Cotton—Aphid and Whitefly Monitoring Supplement to UC IPM Pest Management Guidelines: Cotton www.ipm.ucdavis.edu Take a combined sample for aphids and whitefly at least once a week. Directions: 1. Beginning at least 50 paces into the field, pick a plant at random and turn over the 5th leaf from the terminal. Examine the underside of the leaf with a hand lens. 2. Count the aphids and record the number and color. 3. Check for whitefly adults. If 3 or more are present, note the leaf as infested on the form. 4. Note the presence (+) or absence (-) of large whitefly nymphs in the area defined by a leaf disc. 5. Move 20 paces further into the field and select another plant to examine. Repeat the steps above in 4 representative areas of the field for a total of 40 plants. 6. Compute average infestation levels and compare with treatment thresholds. 7. Check field edges for whitefly migration.
