Meloidogyne incognita, Hoplolaintus galeatus, and North Carolina and Georgia populations of Belonolaimus longicaudatus were introduced singly and in various combinations with Fusarium oxysporum f. sp. vasinfectum on wilt-susceptible 'Rowden' cotton. Of all the nematodes, the combination of the N. C. population of B. longicaudatus with Fusarium promoted greatest wilt development. H. galeatus had no effect on wilt. With Fusarium plus M. incognito or B. longicaudatus, high nematode levels promoted greater wilt than low levels. The combination of either population of B. longicaudatus with M. incognita and Fusarium induced greater wilt development than comparable inoculum densities of either nematode alone or where H. galeatus was substituted for either of these nematodes. Nematode reproduction was inversely related to wilt development. Without Fusarium, however, the high inoculum level resulted in greater reproduction of all nematode species on cotton. Combining M. incognita with B. longicaudatus or H. galeatus gave mutually depressive effects on final nematode populations. The interactions of H. gateatus with B. longicaudatus varied with two populations of the latter.
将南方根结线虫、盖氏全齿垫刃线虫以及北卡罗来纳州和佐治亚州的长针线虫种群，分别单独以及以各种组合形式，与尖孢镰刀菌萎蔫专化型一起接种到感枯萎病的“罗登”棉花上。在所有线虫中，长针线虫北卡罗来纳州种群与镰刀菌的组合促使枯萎病发展最为严重。盖氏全齿垫刃线虫对枯萎病没有影响。对于镰刀菌与南方根结线虫或长针线虫的组合，线虫数量多比数量少更能促使枯萎病加重。长针线虫的任何一个种群与南方根结线虫以及镰刀菌的组合，比单独接种同等接种密度的任何一种线虫，或者用盖氏全齿垫刃线虫替代其中任何一种线虫时，引发的枯萎病发展更为严重。线虫繁殖与枯萎病发展呈负相关。然而，在没有镰刀菌的情况下，高接种量导致所有线虫种类在棉花上的繁殖量增加。南方根结线虫与长针线虫或盖氏全齿垫刃线虫组合，对最终线虫种群数量产生相互抑制作用。盖氏全齿垫刃线虫与长针线虫的相互作用因长针线虫的两个种群而有所不同。
