Hosts. Delphacidae ( Guglielmino & Olmi, 1997) : in Australia: Liburnia sp. (near Chloriona ), Sardia sp. (= Hadeodelphax sp. ); in India: Nilaparvata lugens (Stål) , Sogata sp. , Sogatella furcifera (Horváth) : in Japan: Laodelphax striatellus (Fallén) , Nilaparvata lugens (Stål) , Sogatella furcifera (Horváth) (see remarks after the key to the Oriental species of Haplogonatopus ); in Malaysia: Sogata sp. , Sogatella furcifera (Horváth) ; in the Philippines: Nilaparvata lugens (Stål) , Sogatella furcifera (Horváth) , Stenocranus sp. ; in Sri Lanka: Nilaparvata lugens (Stål) , Sogatella furcifera (Horváth) ; in China (Taiwan): Nilaparvata lugens (Stål) , Tarophagus proserpina (Kirkaldy) .The records of Cicadellidae by Chandra (1978a, 1978b, 1980a, 1980b) and He & Xu (2002) are erroneous (Chandra listed as hosts Nephotettix nigropictus (Stål) , Nephotettix virescens (Distant) and Recilia dorsalis (Motschulsky)) , because Haplogonatopus apicalis parasitizes only Delphacidae .

Biology. Information on biology by Pagden (1934), Kitamura (1987a, 1987b, 1987c, 1988a, 1988b) and Kitamura & Iwami (1998). Gan et al. (2002) discovered in China that both females of H. apicalis and specimens of Nilaparvata lugens (Stål) , Sogatella furcifera (Horváth) and Laodelphax striatellus (Fallén) were infected by Wolbachia , a bacteria living in many insects. The parthenogenesis is thelytokous ( Olmi, 2000a).

Natural enemies. In Malaya ( Pagden, 1934; Olmi, 2000a) H. apicalis is parasitized by the following parasitoids: Ceraphronidae : Allomicrops (= Ceraphron ) abnormis R. Perkins ; Encyrtidae : Cheiloneurus exitiosus (R. Perkins, 1906) ( Guerrieri & Viggiani, 2005) ; Pteromalidae : Eupteromalus sp. In Thailand H. apicalis is parasitized by the following parasitoids: Pteromalidae : Trichomalus sp. 1 (maybe a new species reared in Taiwan, Taipei, 21.VII.1975; VIII.1975; V.1976; VIII.1976; this species was reared from cocoons of H. apicalis by K.S. Lin); Trichomalus sp. 2 (reared in Thailand, Prachin Buri, rice fields, 26.VII.1960; this species was reared from cocoons of H. apicalis by A.T. Barrion).

Distribution. China (Zhejiang, Fujian, Guangdong, Guangxi, Guizhou, Shaanxi, Hubei, Hunan, Henan, Taiwan, Jiangxi, Liaoning, Heilongjiang), Australia (Queensland, New South Wales, Victoria), Japan (Kyushu, Shikoku), India (Chattisgarh, Andhra Pradesh, Bihar, Chattisgarh, Delhi, Jharkhand, Karnataka, Madhya Pradesh, Orissa, Punjab), Malaysia (Malaya, Sarawak), Philippines (Luzon, Panay, Mindoro), Sri Lanka (Kandy), Thailand (Tung Saew, Pasang, Tung Fabad, Banmakok, Chom-Thong).
