Root-knot nematodes (Meloidogyne spp.) cause extensive damage to watermelon ICitrz,llus lanatus (Thunb.) Matsum. & Nakai var. lanatusl, and resistance to rootknot nematodes has not been identified in any watermelon cultivar. Twenty-six U.S. Plant Introductions (Pis) of Citrullus lanatus (Thunb.) Matsum. & Nakai var. citroides (L. H. Bailey) Mansf., one P1 of C. lanatus var. lanatus, and three P...

Meloidogyne christiei n. sp. is described and illustrated from turkey oak (Quercus laevis) in Sanlando Park, Altamonte Springs, Florida. This new nematode species has a distinctive perineal pattern commonly with a high, squarish arch and coarse broken striae which tend to diverge at various angles, especially in and above the anal area. Female labial disc is indented, forming four points or pro...

two fungal species glomus mosseae and glomus intraradices as well as meloidogyne javanica nematode were used in order to evaluate the effects of arbuscular mycorrhizal fungi on control of different populations of root-knot nematode in tomato. a greenhouse test was established as factorial experiment based on completely randomized design with 8 treatments and 4 replicates followed by mycorrhizal...

The purpose of this study was to assess the effects of increasing initial population density (Pi) of Meloidogyne incognita on nematode reproduction and growth of susceptible tomato (Lycopersicom esculentum cv. Round-41) at 25°C± 2 in growth chamber. 21-days-old tomato seedlings transplanted in13-cm dia. earthen pot was inoculated with Pi including 250, 500, 1000, 1500 eggs of M. incognita. Nema...

INTRODUCTION Gall bladder is a pear shaped secular Organ which stores bile, is also place for formation and growth of gall stones. Today the incidence of Cholelithiasis is increasing considerably in India. The aim of our study are to know the incidence of gall stones in relation to age and sex, the relation of diet in gall stones, the clinical presentation of gall stones, the best mode of inves...

Meloidogyne javanica is an important nematode pest of pigeonpea. Thirty-four pigeonpea cultivars and 227 germplasm accessions were evaluated for resistance to M. javanica based on number of galls, egg masses, size of galls, and area of root covered with galls. Galls were not formed on 75% of the cultivars, and no egg masses were observed on the roots of four cultivars (UPAS 120, Pant A3, CO 1, ...

Gall wasps (Hymenoptera: Cynipidae) induce structures (galls) on their host plants that house developing wasps and provide them with protection from natural enemies. The Asian chestnut gall wasp, Dryocosmus kuriphilus Yasumatsu, is an invasive pest that is destructive to chestnut (Castanea spp.). An improved understanding of the interactions among D. kuriphilus, its host, and its natural enemie...

Nonchemical methods and strategies for nematode management including cultural methods and engineered measures have been recommended as an alternative to methyl bromide (a major soil fumigant), due to its role in the depletion of the ozone layer. Hence, an international agreement has recently been reached calling for its reduced consumption and complete phasing out. This present research evaluat...

Plant galls are insect-induced tumor-like growths of plant tissue which nourish and protect developing insect larvae. In all published studies to date, gall size varies (1). Numerous studies demonstrate a positive relationship between success (probability of emergence of the gall-former) and gall size (2-4). Typically, increasing gall size is interpreted as an adaptation to facilitate parasitoi...
