Thirteen plant extracts with standard insecticidal and untreated control were tested. Garlic, Allium sativum (Linn),was found to be best effective followed by Custard apple, Annonasqumosa (Linn) and Bullock heart, Annonareticulate(Linn).

Manisha Gadakh Faculty, Department of Zoology,S.M.B.S.T.College, Sangamner, Ahmednagar – 422605 Email: manisha_gadakh@rediffmail.com INTRODUCTION In Rose aphid, Macrosiphumrosaeformes (Davis) is a key pest of rose,Rosa canine (Linn).This pest causes damage directly by sucking the sap from different parts of the plants and indirectly by transmitting the viral diseases.Heavy infection of this aphid can causes considerable damage to the rose and reducesquality of flower.A number of effective insecticides have been reported for the control of rose aphid.But it is costly and dangerous to ecosystem.For the control of aphid pest various insecticides are recommended and regularly used. But it gives side effect pest resistance (Metcalf, 1988),secondary pest outbreak (Oka and Pimentel,1974), encountered infood animal products adipose tissue and milk (Brown,1974), and effect on non-target organism (Meherotra,1988). Present study was undertaken to evaluate the base data on plant based insecticide specificallyaphidicidal on the given pest which are chief and ecofriendly. MATERIALS AND METHODS A laboratory experiment was conducted at the Department of Zoology, of S.M.B.S.T College, Sangamaner during the year 2013-2014.The rose aphid, M. roseformesand rose twigs were brought to laboratory from field. Various thirteen plant Available online on www.ijprd.com 119 International Journal of Pharmaceutical Research & Development species shown in Table1 were selected for aphidicidal activity test. Plant leaves were firstly washed 2-3 times in sterilized water. 10gms leaves material in 10 ml distilled water.Extracts were allowed to evaporate at room temperature. These materials were squeezed through double layer muslin cloth and paper (Watman No.1). For the experimentation 20 healthy, non pathologic and same size aphids were used for each treatment one ml of each extract was applied on young twigs and aphids in Petri plates.The mortality was recorded after 12,24,36,48 and 60 hrs of post treatment. Recorded data subjected to statistical analysis after regular transformation. RESULTS AND DISCUSSION It was seen from the present study that the mortality in the treated aphid was occurred due to treatment of respective products.The data presented in Table2 indicates that the percent mortality of various plants on aphid at 12,24,36,48,and 60 hours post treatment and study Sr no ISSN: 0974 – 9446 revealed high percent mortality in Garlic, Allium sativum and followed at par Bullock heart,Annonareticulata. The extract of garlic showed highest mortality to compared standard control mortality at 12,24,36,48 and 60 hours posttreatment respectively.Adathodavasica was observed to be effective against, safflower aphid ,U.compositae (Dhembareet. al, 1998). A leaves powder of A. Vasicawas effective on store grain pest(Shrivastava et al. 1964). Pandeyet.al,(1987) reported that O. santumwas better treatment against, L. Erysimi and also Dhembare and Shekatkar(1994) on the same aphid species. Other plant extracts those showed least percent mortality at different hours of post-treatment but these plant extracts might have some other properties such as attaractant, repellent, chemosterilant, fungisidal, nematocidal, bactericidal, rodanticident. But it was beyond the scope of the present study. It was mainly directed towards the aphidicidal and find out baseline data. Table 1 Showing plant species used for insecticidal properties.
