Gossypium arboreum Accessions Resistant to Rotylenchulus reniformis

SALLIANA R. STETINA/ JOHN E. ERPELDING

In the southeastern United States, reniform nematode (Rotylenchulus reniformis) is a serious pest of upland cotton (Gossypium hirsutum), a species which has no naturally occurring resistance against this nematode. To identify sources of reniform nematode resistance in species closely related to upland cotton, 222 G. arboreum accessions from the U.S. germplasm collection were evaluated in repeated growth chamber experiments. In initial screenings, root infection was measured 4 wks after inoculati(..)

Grafting and Paladin Pic-21 for Nematode and Weed Management in Vegetable Production

NANCY KOKALIS-BURELLE/ DAVID M. BUTLER/ JASON C. HONG/ MICHAEL G. BAUSHER/ GREG MCCOLLUM/ ERIN N. ROSSKOPF

Two years of field trials conducted in a Meloidogyne incognita-infested field evaluated grafting and Paladin Pic-21 (dimethyl disulfide:chloropicrin [DMDS:Pic] 79:21) for root-knot nematode and weed control in tomato and melon. Tomato rootstocks evaluated were; ‘TX301’, ‘Multifort’, and ‘Aloha’. ‘Florida 47’ was the scion and the nongrafted control. A double crop of melon was planted into existing beds following tomato harvest. Melon rootstocks, C. metulifer and ‘Tetsukabuto’, were evaluated wit(..)

Distribution and Longevity of Pratylenchus penetrans in the Red Raspberry Production System

DUNCAN R. KROESE/ JERRY E. WEILAND/ INGA A. ZASADA

One of the major constraints on the production of red raspberries in the Pacific Northwest is the presence of the rootlesion nematode Pratylenchus penetrans. Current management of this nematode relies heavily on preplant soil fumigation; however, regulations have made the practice more difficult and expensive. Additional issues with soil fumigation include lack of efficacy at deeper soil depths and potential inability to penetrate raspberry root material that remains in the field during fumigati(..)

Acetic Acid, 2-Undecanone, and (E)-2-Decenal Ultrastructural Malformations on Meloidogyne incognita

NIKOLETTA NTALLI/ MARLENA RATAJCZAK/ CHRISOSTOMOS OPLOS/ URANIA MENKISSOGLU-SPIROUDI/ ZBIGNIEW ADAMSKI

The use of natural compounds to control phytonematodes is significantly increasing, as most of the old synthetic pesticides have been banned due to their eco-hostile character. Plant secondary metabolites are now evaluated as biologically active molecules against Meloidogyne spp. but their target site in the nematode body is rarely specified.Herein, we report on the ultrastructure modifications of the Meloidogyne incognita J2 after treatment with nematicidal plant secondary metabolites, that is (..)

Are Entomopathogenic Nematodes Effective Biological Control Agents Against the Carob Moth, Ectomyelois ceratoniae?

ZAHRA MEMARI/ JAVAD KARIMI/ SHOKOOFEH KAMALI/ SEYED HOSSEIN GOLDANSAZ/ MOJTABA HOSSEINI

The carob moth (Ectomyelois ceratoniae) is the key pest of pomegranate, which causes a significant percentage of losses in pomegranate orchards and warehouses of Iran annually. The pest larvae are characterized by displaying a cryptic behavior within the fruit, which avoids most routine control techniques, especially chemical method. The low efficiency of traditional measurements and also the rich species diversity of natural enemies within the infested fruits highlight the necessity of explorin(..)

Data on Some Species of the Genus Coslenchus Siddiqi, 1978 (Rhabditida, Tylenchidae) from Iran

YOUSEF PANAHANDEH/ EBRAHIM POURJAM/ MAJID PEDRAM

Data on five known species of the genus Coslenchus are provided. Morphological and morphometric data are given for all studied species. Three of the recovered species were also characterized by molecular phylogenetic data. The species C. leiocephalus was studied for the first time since its original description. Males of the species, C. franklinae and C. oligogyrus were described for the first time and the species C. oligogyrus was reported from Iran for the first time. In molecular phylogenetic(..)

New Cyst Nematode, Heterodera sojae n. sp. (Nematoda: Heteroderidae) from Soybean in Korea

HEONIL KANG/ GEUN EUN/ JIHYE HA/ YONGCHUL KIM/ NAMSOOK PARK/ DONGGEUN KIM/ INSOO CHOI

A new soybean cyst nematode Heterodera sojae n. sp. was found from the roots of soybean plants in Korea. Cysts of H. sojae n. sp. appeared more round, shining, and darker than that of H. glycines. Morphologically, H. sojae n. sp. differed from H. glycines by fenestra length (23.5–54.2 mm vs. 30–70 mm), vulval silt length (9.0–24.4 mm vs. 43–60 mm), tail length of J2 (54.3–74.8 mm vs. 40–61 mm), and hyaline part of J2 (32.6–46.3 mmvs. 20–30 mm). It is distinguished from H. elachista by larger cys(..)

Agamermis (Nematoda: Mermithidae) Infection in South Carolina Agricultural Pests

FRANCESCA L. STUBBINS/ PAULA AGUDELO/ FRANCIS P. F. REAY-JONES/ JEREMY K. GREENE

Native and invasive stink bugs (Hemiptera: Pentatomidae) and the closely related invasive Megacopta cribraria (Hemiptera: Plataspidae) are agricultural pests in the southeastern United States. Natural enemies, from various phyla, parasitize these pests and contribute to population regulation. We specifically investigated Nematoda infections in pentatomid and plataspid pests in one soybean field in South Carolina in 2015. Nematodes were identified through molecular and morphological methods and a(..)
