Studies on the biology of the apple sawfly Hoplocampa testudinea Klug (Hym., Tenthredinidae)



Studies on the biology of the apple sawfly Hoplocampa testudinea Klug (Hym., Tenthredinidae)



Prace Instytutu Sadownictwa w Skierniewicach, A78 recd 1980; 20: 201-210



Studies were carried out in Poland in 1968-71 on the biology of Hoplocampa testudinea (Klug) on apple. The first adults emerged just before the pink bud stage of early flowering varieties. Emergence of males and females started at the same time, although at first the ratio of females to males was 1:4. The female:male ratio for the whole of the emergence period was 2:1 and for the oviposition period 3:1.
