''Belonolaimus'' is a genus of nematodes. They are known commonly as sting nematodes.〔(Sting nematodes. ) American Phytopathological Society.〕 They are ectoparasites that feed on plant roots, sometimes becoming agricultural pests.〔 They are found in the United States, Mexico, and Puerto Rico.〔del Prado Vera, I. C. and S. A. Subbotin. (2012). (''Belonolaimus maluceroi'' sp. n. (Tylenchida: Belonolaimidae) from a tropical forest in Mexico and key to the species of ''Belonolaimus''. ) ''Nematropica'' 42(2), 201-10.〕 The genus was erected with the description of ''B. gracilis'' from the roots of a pine tree in Florida in the United States.〔 Other species were soon described from various pine species.〔 ''B. longicaudatus'' was recognized as an important agricultural pest in the southeastern United States.〔 These are some of the largest plant-parasitic nematodes, reaching up to 3 millimeters in length. They feed by inserting their stylets into roots and sucking the contents of root cells. They can be found on fruits, vegetables, other crops such as cotton and soybeans, turfgrasses, and forestry trees. Sting nematodes can cause severe plant damage and have been responsible for complete crop losses. ''B. longicaudis'' is considered to be the worst pest species.〔 Females are fertilized by males, storing sperm in a spermatheca. The females lay several eggs, and there are four juvenile stages.〔 == Species == There are six valid species, but ''B. longicaudis'' is considered a species complex.〔 *''Belonolaimus euthychilus'' * ''Belonolaimus gracilis'' * ''Belonolaimus longicaudatus'' *''Belonolaimus maluceroi'' *''Belonolaimus maritimus'' *''Belonolaimus nortoni'' 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Belonolaimus」の詳細全文を読む スポンサード リンク
