Abstract:
A taxonomic and ecological study to scale insects was conducted with reference to predatory efficiency for four types of predators in the eight areas in Basra province it is( AL - Mdayna , AL - Hoer , Al - Qurna , AL - Deer , AL - Hartha , AL - Garma , Shat AL - Arab , Abu AL - Khseb ) during the period from October 2014 to September 2015 and show that there is a five types of scale insects belong to three families : Order : Hemiptera Suborder : Sternorrhyncha Superfamily : Coccoidea 1 - Family : Diaspididae Genus : Parlatoria Parlatoria blanchardi white scale insect on the palm Parlatoria crypta brown scale insect on the oleander Genus : Duplachionaspis Duplachionaspis graminella scale insect on the reeds Family : Phoenicococcidae - 2Pheonicococcus marlatti red scale insect on the palmFamily : Asterolecaniidae - 3Palmaspis Phoenicis green scale insect on the Palm Taxonomic study showed that there is difference diagnostic a clear between the species , genus and families found during the survey . The results pointed clearly of ecological study that the types of scale insects are located throughout the year on their hosts plant in Basra province .The highest density of numerical insects was recorded in month of June and it reached about 300.0 adult and 93.6 nymph per inch2 on variety khathraoe in the Al - Madayna area of scale insect Parlatoria blanchardi and 91.6 adult /inch2 , 25.0 nymph/inch2on variety khathraoe in the AL - Qurna area of scale insectbPalmaspis phoenicis , 11.6 adult/leaf , 6.0 nymph /leaf on Oleander plant in the Al - Qurna area of scale insect Parltoria crypta , 63.0 adult /inch2 , 5.3 nymph/inch2 on reed plant in November in the Al - Mdayna area of scale insect Duplachionaspis graminella . The less intensity of numerical insect recorded in February .It was 130.3adult/inch2 and 20.3 nymph /inch2 on variety khathraoe in the Al - Mdayna area of scale insect Parlatoria blanchardi , 42.6 adult /inch2 , 6.6 nymph/inch2 on variety khathraoe in the Al - Qurna area at scale insect Palmaspis phoenicis , 5.3 adult /leaf , 0.0 nymph /leaf on Oleander plant in the Al - Qurna , 26.6 adult /inch2 and 0.3 nymph /inch2 on reed plant in Al - Mdayna area . The study was in clued the efficiency of predatorys as following : Coccinella septempunctata which appeared during the months March , April , May and June. Pharoscymnus setulosus and Cybocephalus rufifrons which appeared during the months May, June , Jule , August , September, October and November . The predatory efficiency of first predator was 16.6 insect/day ,to the second 16.0 insect /day and the third 13.0 insect /day on white scale insect then , 17.3 , 17.0 and 13.3 insect /day respectively on green scale insect . And the predatory efficiency to Tenebrio molitor was 3.3 insect /day on red scale insect .
