The Invasive Alien Leaf Miner Cameraria Ohridella and the Native Tree Acer Pseudoplatanus: a Fatal Attraction?
1 The invasive alien leaf miner Cameraria ohridella and the native tree Acer pseudoplatanus: a fatal attraction? Christelle Per´ e†,´ Sylvie Augustin∗, Ted C. J. Turlings† and Marc Kenis CABI Europe-Switzerland, 2800 Del´emont, Switzerland, ∗INRA, UR 633 Zoologie Foresti`ere, 45000 Orl´eans, France and †Institute of Zoology, University of Neuchˆatel, 2009 Neuchˆatel, Switzerland Abstract 1 The horse-chestnut leaf miner Cameraria ohridella is an invasive moth in Europe and a serious pest of horse-chestnut Aesculus hippocastanum. The moth also occasionally attacks sycamore maple Acer pseudoplatanus, when situated beside infested horse-chestnuts. 2 The main objective of the present study was to provide an overview of the relationship between C. ohridella and A. pseudoplatanus and to determine whether C. ohridella has the potential to shift to this native tree. 3 In the field, females oviposit on different deciduous tree species. Although less frequently attacked than A. hippocastanum, A. pseudoplatanus was clearly preferred for oviposition over 12 other woody species investigated. 4 Surveys in Europe demonstrated that the majority of A. pseudoplatanus trees found beside infested A. hippocastanum had mines of C. ohridella, even though more than 70% of the larvae died within the first two instars. Attack rates and development success greatly varied from site to site. Attack levels on A. pseudoplatanus were not always correlated with those on A. hippocastanum, and mines on A. pseudoplatanus were sometimes observed beside weakly-infested A. hippocastanum. 5 Field observations, experimental exposure of A. pseudoplatanus saplings and rearing trials in a common garden study showed that individual trees may vary in their susceptibility to C. -
Karyotype and Genome Size Determination of Jarilla Chocola, an Additional Sister Clade of Carica Papaya
POJ 14(01):50-56 (2021) ISSN:1836-3644 doi: 10.21475/POJ.14.01.21.p2944 Karyotype and genome size determination of Jarilla chocola, an additional sister clade of Carica papaya Dessireé Patricia Zerpa-Catanho1, Tahira Jatt2, Ray Ming1* 1Department of Plant Biology, University of Illinois at Urbana-Champaign, Urbana, IL 61801, USA 2Department of Botany, Shah Abdul Latif University, Khaipur, Sindh, 66020, Pakistan *Corresponding author: [email protected] Abstract Jarilla chocola is an herbaceous plant species that belongs to the Jarilla genus and the Caricaceae family. No information on chromosome number or genome size has been reported for J. chocola that confirms the occurrence of dysploidy events and explore the existence of heteromorphic sex chromosomes. Therefore, the total number of chromosomes of this species was determined by karyotyping and counting the number of chromosomes observed, and the genome size of female and male plants was estimated separately by flow cytometry. Results showed that J. chocola has eight pairs of chromosomes (2n = 2x = 16), and its chromosomes are classified as metacentric for five pairs, submetacentric for two pairs and telocentric for one pair. The nuclear DNA content (1C- value) in picograms and diploid genome size was estimated separately from female and male plants using two species as the standards, Phaseolus vulgaris (1C = 0.60 pg) and Carica papaya (1C = 0.325 pg), to look for the possible existence of heteromorphic sex chromosomes. C. papaya proved to be a better standard for the determination of J. chocola DNA content and diploid genome size. No significant difference on the DNA content was observed between female (1C = 1.02 ± 0.003 pg) and male (1C = 1.02 ± 0.008 pg) plants. -
The Use of Vasconcellea Wild Species in the Papaya Breeding (Carica Papaya L.- Caricaceae): a Cytological Evaluation
The use of Vasconcellea wild species in the papaya breeding (Carica papaya L.- Caricaceae): a cytological evaluation Telma N. S. Pereira, Monique F. Neto, Lyzia L. Freitas, Messias G. Pereira Universidade Estadual do Norte Fluminense Darcy Ribeiro - Campos dos Goytacazes - RJ -Brazil Introduction Papaya is a fruit species grown in tropical and subtropical regions. The cultivars of this species are all susceptible to ring spot mosaic virus; however, there is in the Caricaceae family wild species that exhibit resistance genes to the virus as Vasconcellea cauliflora, V. cundinamarcensis, V. quercifolia, and V. stipulata. But, interspecific/intergeneric hybrids are not obtained between the wild species and the cultivated one, thus preventing the introgression of important genes in the cultivated form. The objectives of this study were to generate cytogenetic knowledge by karyotype determination and species meiotic behavior.The study was conducted on C.papaya, V.quercifolia,V.cundinamarcensis, V.cauliflora,V.goudotiana, and V.monoica by routine laboratory methodology.

Packauskas1 Abstract Forty eight species of Pentatomidae are listed as occurring in the state of Kansas, nine of these are new state records. A key to all species known from the state of Kansas is given, along with some notes on new state records. ____________________ The family Pentatomidae, comprised of mainly phytophagous and a few predaceous species, is one of the largest families of Heteroptera. Some of the phytophagous species have a wide host range and this ability may make them the most economically important family among the Heteroptera (Panizzi et al. 2000). As a group, they have been found feeding on cotton, nuts, fruits, veg- etables, legumes, and grain crops (McPherson 1982, McPherson and McPherson 2000, Panizzi et al 2000). -

A New Species of Ceratosolen from the Philippines (Hymenoptera: Agaonidae)
Genus Vol. 19(2): 307-312 Wrocław, 31 VII 2008 A new species of Ceratosolen from the Philippines (Hymenoptera: Agaonidae) STEVEN R. DAVIS1 & MICHAEL S. ENGEL2 Division of Entomology, Natural History Museum, and Department of Ecology & Evolutionary Biology, 1501 Crestline Drive – Suite 140, University of Kansas, Lawrence, Kansas 66049-2811, United States, e-mails: [email protected], [email protected] ABSTRACT. A new species of fig wasp, Ceratosolen (Ceratosolen) polyodontos n. sp., is described from females captured at Los Baños, Luzon, Philippines. The species can be distinguished from its congeners by the possession of a much greater number of ventral mandibular lamellae (22–23), divided into an anterior and posterior area, and posterior metasomal structures associated with the ovipositor. Key words: entomology, taxonomy, Chalcidoidea, fig wasp, Philippines, Southeast Asia, new species, Agaoninae. INTRODUCTION The obligate mutualism between Ficus trees and fig wasps (Chalcidoidea: Agao- nidae) has existed for million years (GRIMALDI & ENGEL 2005; PEÑALVER et al. 2006). While approximately 640 agaonid species are presently described worldwide, estimates indicate that this is likely merely one-half of the total fig wasp diversity. W IEBES (1994) provided the most comprehensive treatment of the Indo-Malayan agaonid fauna. Despite the various inadequacies of this work it is nonetheless a very valuable entry point into the fauna and a necessary foundational stone for building more rigorous revisionary work, comparative studies, and biological investigations. One of the more notable genera occurring in the Indo-Malayan fauna is the genus Ceratosolen. Ceratosolen is divided into three subgenera – Rothropus, Strepitus, and Ceratosolen proper – distributed across Africa, India, Australia, Malagasy, Malaysia, Indonesia, Melanesia, Polynesia, and the Philippines. -

We explore the influence of each gene region on the support given to each node of the most parsimonious tree derived from a combined analysis of all three genes using Partitioned Bremer Support. We also explore the influence of assuming equal weights for all characters in the combined analysis by investigating the stability of clades to different transition/transversion weighting schemes. We find many strongly supported and stable clades in the Nymphalinae. We are also able to identify ‘rogue’ -
Descriptions of Two New Chlosyne (Nymphalid~) from Mexico, with a Discussion of Related Forms
148 Vo1.14: no.Z DESCRIPTIONS OF TWO NEW CHLOSYNE (NYMPHALID~) FROM MEXICO, WITH A DISCUSSION OF RELATED FORMS by DAVID L. BAUER Some years ago while examining the series of C hlosyne lacinia Geyer in the collection of F. M. BROWN, I noticed five specimens without marginal or submarginal spots on the wings. These specimens were all from northeastern Mexico and this along with their other peculiarities interested me, so I set them aside and continued to examine the series. Later among the specimens of C hlosyne lacinia quehtala Reakirt, I found five more specimens which also did not have a trace of the marginal or submarginal spots on their wings. These last specimens were from southwestern Mexico. As soon as possible I examined the genitalia of these two insects to see if they were just another variation of the protean C. lacinia, of which I had already checked many forms, or something new. I was both surprised and delighted to find the genitalia w ere definitely not like those of true lacinia. Comparison with the genitalia of other species of Chlosyne showed them to be most like those of C. janais Drury. The next summer, 1954, a trip was taken to Mexico and several colonies of the first insect were found, its habits were observed, and a good series was collected, but only one specimen of the second insect was c3.ptured. However, that same year, and also two years later, KENT H. WILSON was collecting Papilio in Mexico, and knowing of my interest in the Chlosyne he collected as many as he could and sent them to me for study. -
The Symphyta of the Afrotropical Region. Genus Athalia LEACH, 1817, Athalia Himantopus-Group (Insecta: Hymenoptera: Tenthredinidae: Allantinae)

Genus Athalia LEACH, 1817, Athalia himantopus-group (Insecta: Hymenoptera: Tenthredinidae: Allantinae) Frank KOCH Abstract The Athalia himantopus-group of the sawfly family Tenthredinidae is revised, and a key is provided for the eight known Afrotropical species. The species of this group are characterised by the presence of a short and more or less truncate clypeus. Four species are re-described and four species are described as new to science, namely: Athalia erythraeana sp. n., A. flavobasalis sp. n., A. sidamoensis sp. n. and A. taitaensis sp. n. The subspecies A. himantopus truncata ENSLIN, 1914 and A. himantopus obsoleta BENSON, 1962, are interpreted as valid species - A. truncata ENSLIN stat. rev. and A. obsoleta BENSON stat. n. Athalia marginipennis Enderlein, 1920 sp. rev., which is distributed from East to southern Africa, is a valid species and is removed from synonymy with A. sjoestedti KONOW, 1907. The phenology of A. flavobasalis and A. marginipennis is discussed, based on material from a series of yellow pan trap samples collected from February 1981 to June 1983 at Munanira, Burundi. All species are figured, and their distribution and relationships are discussed. Introduction Following the revision of the endemic Afrotropical Athalia vollenhoveni species-group (KOCH 2006), this contribution deals with the A. himantopus species-group, and is a further contribution to a broader taxonomic- systematic revision of the Afrotropical Symphyta, especially the genus Athalia LEACH, 1817, the main purpose of which is to reconstruct the phylogeny and historical distribution patterns of the group. -
