Occurrence of Panagrellus (Rhabditida: Panagrolaimidae) Nematodes in a Morphologically Aberrant Adult Specimen of Rhynchophorus ferrugineus (Coleoptera: Dryophthoridae)

MANUELA CAMEROTA/ GIUSEPPE MAZZA/ LYNN K. CARTA/ FRANCESCO PAOLI/ GIULIA TORRINI/ CLAUDIA BENVENUTI/ BEATRICE CARLETTI/ VALERIA FRANCARDI/ PIO FEDERICO ROVERSI

An aberrant specimen of Rhynchophorus ferrugineus (Coleoptera: Dryophthoridae) also known as red palm weevil (RPW), the most economically important insect pest of palms in the world, was found among a batch of conspecifics reared for research purposes. A morphological analysis of this weevil revealed the presence of nematodes associated with a structured cuticle defect of the thorax. These nematodes were not able to be cultured, but were characterized by molecular analysis using 28S and 18S ribo(..)

First Report of the Carolina Spiral Nematode, Scutellonema brachyurus, from Soil of a Garden in Crete, Greece

EMMANUEL A. TZORTZAKAKIS/ CAROLINA CANTALAPIEDRA-NAVARRETE/ ANTONIO ARCHIDONA-YUSTE/ JUAN E. PALOMARES-RIUS/ PABLO CASTILLO

Members of the genus Scutellonema can cause substantial crop losses to ornamental and cultivated plants directly by feeding ectoparasitically on plant roots (Bridge et al., 2005; Coyne et al., 2006). In May 2015, a soil sample from a house garden from Heraklion city in Crete, Greece, was sent for diagnosis of plant-parasitic nematodes. In this place, there had been cactus (Opuntia sp.) plants (probably imported), which were uprooted 3 to 4 years earlier. After that, the area was cropped with cuc(..)

Oscheius tipulae in Italy: Evidence of an Alien Isolate in the Integral Natural Reserve of Montecristo Island (Tuscany)

GIULIA TORRINI/ GIUSEPPE MAZZA/ AGOSTINO STRANGI/ DELFINA BARABASCHI/ SILVIA LANDI/ EMILIANO MORI/ MATTIA MENCHETTI/ PAOLO SPOSIMO/ CLAUDIA GIULIANI/ ANTONIO ZOCCOLA/ LORENZO LAZZARO/ GIULIO FERRETTI/ BRUNO FOGGI/ PIO FEDERICO ROVERSI

Montecristo Island is an integral natural reserve of the Tuscan Archipelago National Park (Central Italy), characterized by a peculiar assemblage of flora and fauna, with several endemic taxa, and also with a high number of alien species. During a soil survey, we found an alien Oscheius tipulae Lam &Webster, 1971 isolate, phylogenetically close to others from South America. In this article, we examined the possible pathways of introduction of this nematode. Because of the high number of alien pl(..)

Resistance to Southern Root-knot Nematode (Meloidogyne incognita) in Wild Watermelon (Citrullus lanatus var. citroides)

JUDY A. THIES/ JENNIFER J. ARISS/ CHANDRASEKAR S. KOUSIK/ RICHARD L. HASSELL/ AMNON LEVI

Southern root-knot nematode (RKN, Meloidogyne incognita) is a serious pest of cultivated watermelon (Citrullus lanatus var. lanatus) in southern regions of the United States and no resistance is known to exist in commercial watermelon cultivars. Wild watermelon relatives (Citrullus lanatus var. citroides) have been shown in greenhouse studies to possess varying degrees of resistance to RKN species. Experiments were conducted over 2 yr to assess resistance of southern RKN in C. lanatus var. citro(..)

Molecular and Morphological Characterization of Xiphinema chambersi Population from Live Oak in Jekyll Island, Georgia, with Comments on Morphometric Variations

ZAFAR A. HANDOO/ LYNN K. CARTA/ ANDREA M. SKANTAR/ SERGEI A. SUBBOTIN/ STEPHEN W. FRAEDRICH

A population of Xiphinema chambersi from the root zone around live oak (Quercus virginiana Mill.) trees on Jekyll Island, GA, is described using both morphological and molecular tools and compared with descriptions of type specimens. Initially, because of a few morphological differences, this nematode was thought to represent an undescribed species. However, on further examination, the morphometrics of the nematodes from live oak tend to agree with most of the morphometrics in the original descr(..)

Morphological and Molecular Characterization of Two Aphelenchoides Endophytic in Poplar Leaves

LYNN K. CARTA/ SHIGUANG LI/ ANDREA M. SKANTAR/ GEORGE NEWCOMBE

During a long-term, large network study of the ecology of plant endophytes in native habitats, various nematodes have been found. Two poplar species, Populus angustifolia (narrowleaf cottonwood) and Populus trichocarpa (black cottonwood), are important ecological and genomic models now used in ongoing plant–pathogen–endophyte interaction studies. In this study, two different aphelenchid nematodes within surface-sterilized healthy leaves of these two Populus spp. in northwestern North America wer(..)

Molecular and Morphological Characterization of Aphelenchoides fuchsi sp. n. (Nematoda: Aphelenchoididae) Isolated from Pinus eldarica in Western Iran

MEHRAB ESMAEILI/ RAMIN HEYDARI/ MOZHGAN ZIAIE/ JIANFENG GU

Aphelenchoides fuchsi sp. n. is described and illustrated from bark and wood samples of a weakened Mondell pine in Kermanshah Province, western Iran. The new species has body length of 332 to 400 mm (females) and 365 to 395 mm (males). Lip region set off from body contour. The cuticle is weakly annulated, and there are four lines in the lateral field. The stylet is 8 to 10 mm long and has small basal swellings. The excretory pore is located ca one body diam. posterior to metacorpus valve or 51 t(..)

Assessment of DAPG-producing Pseudomonas fluorescens for Management of Meloidogyne incognita and Fusarium oxysporum on Watermelon

SUSAN L. F. MEYER/ KATHRYNE L. EVERTS/ BRIAN MCSPADDEN GARDENER/ EDWARD P. MASLER/ HAZEM M. E. ABDELNABBY/ ANDREA M. SKANTAR

Pseudomonas fluorescens isolates Clinto 1R, Wayne 1R, and Wood 1R, which produce the antibiotic 2,4-diacetylphloroglucinol (DAPG), can suppress soilborne diseases and promote plant growth. Consequently, these beneficial bacterial isolates were tested on watermelon plants for suppression of Meloidogyne incognita (root-knot nematode: RKN) and Fusarium oxysporum f. sp. niveum (Fon). In a greenhouse trial,Wayne 1R root dip suppressed numbers of RKN eggs per gram root on ‘Charleston Gray’ watermelon (..)

Optimum Concentrations of Trichoderma longibrachiatum and Cadusafos for Controlling Meloidogyne javanica on Zucchini Plants

ZAHRA SOKHANDANI/ MOHAMMAD REZA MOOSAVI/ TAHEREH BASIRNIA

A factorial experiment was established in a completely randomized design to verify the effect of different inoculum levels of an Iranian isolate of Trichoderma longibrachiatum separately and in combination with various concentrations of cadusafos against Meloidogyne javanica in the greenhouse. Zucchini seeds were soaked for 12 hr in five densities (0, 105, 106, 107, and 108 spores/ml suspension) of the fungus prior to planting in pots containing four concentrations of cadusafos (0, 0.5, 1, and 2(..)
