ASTEROLECANIIDAE 43. x Asterodiaspis quercícola (Bouché, 1851) - Quercus petraea, 18. 07. 1986. Magdatsesty, dead females, first and second instar larvae, F=l (2967). 44. Asterodiaspis variolosa (Ratzeburg, 1870) - It was known earlier in Moldavia (VERESHAGIN 1983). We collected it on Quercus petraea, 15. 07. 1986, Kotovsk, females, F=l (2931). 45. x Planchonia arabidis Signorét, 1876 - Salvia sp., 17. 07. 1986, Goyan, females, F=l (2953). DlASPIDTDAE 46. x Aspidlotus nerii Bouché, 1833 - Phoenix sp., on indoor plant, 16. 07. 1986, Kodry, females, F=4 (2935). 47. x Aulacaspis rosae (Bouché. 1834) - Rosa canina, 16. 07. 1986, Kodry, dead females, F=l (2947). 48. Epidiaspis leperli (Signorét, 1869) - Widely distributed pest in Moldavia (GOANCA et al., 1974). We collected it on Pyrus communis treated by pesticides, 17. 07. 1986, Kisinev, dead females, F=l (2949). 49. + Lepidosaphes tiliae (Savescu, 1957) - Tilia sp., 15. 07. 1986, Bardar, females, males, eggs, F=3 (2922). This species is morphologically so closely related to L. ulmi that further investigations will be necessary to ascertain the status of these two taxa. 50. Lepidosaphes ulmi (Linnaeus, 1758) - Widely distributed pest in Moldavia (GOANCA et al., 1974). We collected it on Tilia sp., 03. 09. 1985, Kisinev, dead females, F=4 (2741); Malus domestica treated by pesticides, 16. 07. 1986, Kodry, dead females, F=3 (2936); Crataegus monogyna, 17. 07. 1986, Goyan, females, eggs, F=3 (2951); Crataegus monogyna, 17. 07. 1986, Trebuzheny, females, eggs, F=2 (2 9 56); Quercus petraea, 18. 07. 1986, Magdatsesty, dead females, F=l (2967). 51. x Leucaspis loewi (Colvée, 1882) - Pinus nigra, 03. 09. 1985, Kisinev, females, F=2 (2740). 52. x Quadraspidiotus gigas (Thiem and Gerneck, 1934) - Populus sp., 28. 05. 1985, Kisinev, females, F=2 (2660); Populus sp., o4. 09. 1985, Vladimirovka, dead females, first instar larvae, F=4 (2745); Populus sp., 04. 09. 1985, Tiraspol, dead females, F=4 (2746). 53. Quadraspidiotus marani Zahradnlk, 1952 - Rare pest in Moldavia (GOANCA et al. 1974). 54. Quadraspidiotus ostreaeformis (Curtis, 1843) - Important pest in Moldavia (GOANCA et al. 1974). 55. Quadraspidiotus perniciosus (Comstock, 1881) - Important pest in Moldavia (GOANCA et al. 1974). We collected it on Sorbus sp.,15. 07. 1986, Kisinev, dead females, F=2 (2920); Malus domestica, treated by pesticides, 16. 07. 1986, Kodry, dead females, F=l (2936). 56. Quadraspidiotus pyri (Lichtenstein, 1881) - Important pest in Moldavia (GOANCA et al. 1974). 57. Quadraspidiotus zonatus (Frauenfeld, 1868) - It was reported from Moldavia by BORCHSENIUS (1966). We collected it on Quercus petraea, 15. 07. 1986, Kotovsk, dead females, F=l (2931). Our collectings of scale insects in the middle region of Moldavia yielded 48 species, so the total number of known species reached 57 belonging to 8 families namely: Ortheziidae (2), Pseudococcidae (15), Eriococcldae (5), Kermesidae (4), Cerococcidae (1), Coccldae (15), Asterolecaniidae (3), Diaspididae (12). The species Cerococcus cycliger Goux, 1932; Kermes ilicis (Linnaeus, 1758) and Lepidosaphes tiliae Savescu, 1957 proved to be new for the scale insect fauna of the USSR. From zoogeographieal point of view the scale Insect fauna in this region is very heterogenous. One can find althogether such boreal species as Parafairmairia gracilis

, Vittacoccus longicornis and mediterranean Kermes ilicis or European-sub-Mediterranean Cerococcus cycliger. This region de serves more intensive studies for a complete exploration of its scale insect fauna.
