| redescription of steinernema longicaudum shen & wang (nematoda: steinernematidae); geographic distribution and phenotypic variation between allopatric populations. | steinernema longicaudum shen & wang is redescribed based on a comparative morphological study of specimens from the type isolate from china, and two other isolates recovered from korea and the usa. for the first and second generation female, the location of the vulva, shape of the vulval lips, and shape and length of the tail were newly observed diagnostic characters. a more detailed description of the morphology of the male spicules and gubernaculum, and the arrangement of the genital papillae ... | 2001 | 11316477 |
| steinernema aciari sp. n. (nematoda: steinernematidae), a new entomopathogenic nematode from guangdong, china. | a new species of entomopathogenic nematode, steinernema aciari sp. n. was described. it was recovered from a soil sample collected from haimen town, shantou district in the eastern coast of guangdong province, the people's republic of china during a survey for entomopathogenic nematodes. s. aciari sp. n. belongs to the steinernema glaseri group. it can be separated from all described steinernema species by the combined morphological and morphometrical characters of various stages of the nematode ... | 2004 | 15707870 |
| increased efficacy of entomopathogenic nematode-insecticide combinations against holotrichia oblita (coleoptera: scarabaeidae). | combinations of entomopathogenic nematodes steinernema longicaudum x-7 and heterorhabditis bacteriophora h06 with chlorantraniliprole, diflubenzuron, and imidacloprid insecticides at different rates for the control of the white grub, holotrichia oblita faldermann (coleoptera: scarabaeidae), were evaluated both in the laboratory and in peanut fields. in the laboratory, the combinations had a synergistic or additive effect on the second-instar larvae of h. oblita and caused faster mortality than o ... | 2017 | 28017929 |
| efficacy of entomopathogenic steinernema and heterorhabditis nematodes against white grubs (coleoptera: scarabaeidae) in peanut fields. | the efficacy of entomopathogenic nematodes (epns) against the white grub holotrichia parallela motschulsky (coleoptera: scarabaeidae) in the peanut (arachis hypogaea l.) fields was evaluated. in the first experiment with a high initial white grub population (24.65 +/- 2.44 larvae per m2) in the field, steinernema longicaudum x-7 and heterorhabditis bacteriophora h06 at 10,000 and 5,000 infective juveniles (ijs) per plant contributed to significantly higher percentage reduction of the white grub ... | 2013 | 23865174 |
| a self-fertile species of steinernema from indonesia: further evidence of convergent evolution amongst entomopathogenic nematodes? | more than 20 species of the entomopathogenic nematode steinernema have been described; to date, all reproduce exclusively by cross-fertilization of male and female individuals. steinernema sp. strain t87 from indonesia was found to consist largely of self-fertile hermaphrodites. progeny were produced by morphological females both in insects (galleria mellonella) and in hanging drops of insect haemolymph inoculated with a single infective juvenile. sperm were present in the oviduct of unmated mor ... | 2001 | 11272649 |
