Dinamika populasi wereng punggung putih, sogatella furcifera Stål (Hemiptera: Delphacidae) di jawa tengah

A field study was conducted at paddy fields in Petarukan and Pekalongan regencies of Central Java province during wet season crop 1989/90 and 1990/91 to elucidate population dynamic of whitebacked planthopper,<em> Sogatella furcifera</em> Stål. Seven and three observation fields were set...
