The rise to importance of N. lugens as a tropical pest in the last 20 years coincided with the widespread cultivation of modern, high- yielding dwarf varieties, and with increased use of nitrogen fertilisers and pesticides. The major strategy for control of this insect has been the development of resistant rice cultivars. This work was pioneered and still continues to great effect at the International Rice Research Institute (IRRI) in the Philippines. The work has been summarised in a valuable symposium volume (IRRI, 1979). Many thousands of traditional varieties and wild species of Oryza have been identified that confer resistance to rice plants. At least three genes for resistance have been incorporated into high-yielding varieties. By selection, three separate populations were established, one reared only on the variety TN1, regarded as universally susceptible and lacking any known gene for resistance, a second on the Indian variety Mudgo, which incorporates the gene Bphl, and a third on another Indian variety ASD7, which incorporates the gene 6ph2. These populations were termed biotypes 1, 2 and 3 respectively. Some of this work is reviewed by Saxena and Khan (1989). 

The concept of biotypes as discrete and quite separate entities, identifiable in different parts of Asia, has been widely supported. However, studies of individual insects from the highly inbred populations of the IRRI biotype cultures have shown great variation in virulence (e.g. Claridge and Den Hollander, 1980; Den Hollander and Pathak, 1981; Claridge and Den Hollander, 1982). It seems that N. lugens populations adapt locally to the rice cultivars being grown in any region. Clearly, populations with similar virulence patterns may develop in many different regions quite independently and probably by different genetic means. It is, therefore, misleading to use a terminology of numbering or naming of biotypes from different regions (Claridge and Den Hollander, 1983). It should be noted that some workers still insist on the utility of the biotype nomenclature.

Recently, very interesting populations, morphologically indistinguishable from N. lugens, have been found feeding and reproducing on the grass Leersia hexandra in the Philippines (Heinrichs and Medrano, 1984). Experimental transfers of the Leersia -feeding populations to rice and of the rice-feeding ones to Leersia, showed very poor survival and no successful reproduction on the non-host plant. Similar results were obtained by Claridge and co-workers (Claridge et al., 1985a). In addition, the two populations were shown not to interbreed when given a choice, primarily because of differences in acoustic signals used during courtship. It was concluded that the Leersia feeding populations in the Philippines represent a distinct sympatric sibling species, differing in host plant preferences and in behaviour from the rice-feeding populations. Further studies have noted similar Leersia-feeding populations from India, Sri Lanka, Indonesia and Australia (Claridge et al., 1988). In all regions the sympatric rice and Leersia-associated populations differ in acoustic signals and do not interbreed in the field. It is clear, therefore, that N. lugens should still be regarded as a very specific feeder, restricted only to rices, with a closely related species feeding and reproducing only on Leersia. Unfortunately no reliable morphological differences have yet been demonstrated which may be used to separate the two.
