Flaih3 1Biology Department, College of Science for Women, University of Baghdad, Iraq 2Department of Higher Studies, University of Baghdad, Iraq 3Plant Protection Department, College of Agriculture, University of Baghdad, Iraq Article published on August 30, 2018 Key words: Agromyzid leafminers, Liriomyza bryoniae, Phytomyza horticola. Abstract In Iraq, the leafminer, is one of the most destructive pests of vegetables. Vegetable crops, such as squash Curcurbita pepo L. and tomatoes Solanum lycopersicum L were surveyed to record abundance and diversity of agromyzid leafminers and their natural enemy species. Population density of these pests were studied for the period from April to June 2014 in the College of Agriculture, University of Baghdad- Abu Ghraib. Two leafminers were detected, including Liriomyza bryoniae (Kaltenbach) on squash crop and Phytomyza horticola Gaureue on tomato crop. The results revealed that infestation by Leafminer, L. bryoniae and P. horticola were initiated on leaves situated on the median level of squash and tomato plants, then on leaves of lower level. Because, adults don’t tend to lay eggs on young leaves so that reflected on larval density on these leaves. The rate of larvae numbers of tested insect through the growth season showed that squash's and tomato's leaves of median level were more preferred for leafminer's larvae through the growth season.

The present investigation was carried out to study the parasitoid diversity of this pest in different agroclimatic conditions of Himachal Pradesh, India. Sixteen species of parasitoids viz. Diglyphus horticola Khan, Diglyphus isaea (Walker), Zagrammosoma sp., Pnigalio sp., Quadrastichus plaquoi Reina and LaSalle, Asecodes erxias (Walker), Closterocerus sp., Neochrysocharis formosa (Westwood), Chrysocharis sp, Chrysocharis indicus Khan, Pediobius indicus Khan (Eulophidae), Opius exiguus (Wesmael), Dacnusa sp. (Braconidae), Cyrtogaster sp., Sphegigaster sp. (Pteromalidae), and Gronotoma sp. (Figitidae) were recorded parasitizing C. horticola in different agro-climatic zones of Himachal Pradesh. Agro-climatic zone II (sub-temperate mid-hills) was the richest in parasitoid diversity (14 species) followed by zone I (11 species), zone III (7 species) and zone IV (4 species) which are characterized by sub-tropical sub-montane, wet temperate high hills and dry temperate high hills, respectively.

(Asteraceae) and the related native species Solidago virgaurea L. in Japan. We found large differences in community composition on the two Solidago species. Five hemipteran sap feeders were found only on S. altissima. Two of them, the aphid Uroleucon nigrotuber- culatum Olive (Hemiptera: Aphididae) and the scale insect Parasaissetia nigra Nietner (Hemiptera: Coccidae), were exotic species, accounting for 62% of the total individuals on S. altissima. These exo- tic sap feeders mostly determined the difference of community composition on the two plant species. In contrast, the herbivore community on S. virgaurea consisted predominately of five native insects: two lepidopteran leaf chewers and three dipteran leaf miners. Overall species richness did not differ between the plants because the increased species richness of sap feeders was offset by the decreased richness of leaf chewers and leaf miners on S. altissima. The overall density of herbivorous insects was higher on S. altissima than on S. virgaurea, because of the high density of the two exotic sap feeding species on S.

  • Efficacy of Some Insecticides in the Management of Liriomyza Brassicae on Pisum Sativum Deepti Mondol Department of Zoology Scottish Church College, Kolkata, India
    ISSN XXXX XXXX © 2016 IJESC Research Article Volume 6 Issue No. 7 Efficacy of Some Insecticides in the Management of Liriomyza Brassicae on Pisum Sativum Deepti Mondol Department of Zoology Scottish Church College, Kolkata, India Abstract: The present study was carried out to evaluate the efficacy of insecticides in monitoring the damage caused by Liriomyza brassicae on the pea crop var. ‘Arpana’ in Allahabad. Seven insecticides for the treatment were viz. imidacloprid 17.8 SL @ 0.01%, cypermethrin 25 [email protected]%, emamectin benzoate 5 [email protected]%, endosulfan 35 [email protected]%, acephate 75 [email protected]%, chlorpyriphos 20 [email protected]% and dimethoate 30 [email protected]%. The insecticides were found to be significantly superior over the control in managing the pest population. The order of efficacy was dimethoate > cypermethrin > chlorpyriphos > imidacloprid > acephate > endosulfan > emamectin benzoate > control. Dimethoate (0.06%) gave lowest percent larval population after spraying followed by cypermethrin (0.0075%). Chlorpyriphos (0.04%), imidachloprid (0.01%), acephate (0.15%) were found to be statistically at par with each other. Endosulfan (0.07%), and emamectin benzoate (0.0025%) were amongst the least effective in controlling the pest population. Keywords: Insecticides, leaf miner, Liriomyza brassicae, Pisum sativum.

  • 1490 OVERVIEW of LEAF MINER FAUNA in SERBIA Jovan
    OVERVIEW OF LEAF MINER FAUNA IN SERBIA Jovan DOBROSAVLJEVIC1*, Cedomir MARKOVIC1, Stefan BOJIC2 1University of Belgrade, Faculty of Forestry, KnezaViseslava 1, 11030 Belgrade, Serbia 2University of East Sarajevo, Faculty of Agriculture, Department of Forestry, VukaKaradzica 30, 71123 East Sarajevo, Bosnia and Herzegovina *Corresponding author: [email protected] Abstract Due to their specific lifestyle, frequency of occurrence, and the damage that they cause on plants, leaf miners have been investigated by many scientists in Serbia. Unfortunately, the overview of research on their fauna in Serbia has not been done yet. Therefore, based on the data from the literature sources and the results of our research, the first overview of leaf miner fauna research in Serbia was made. It was found that 363 species of leaf miners were ascertained in Serbia so far. They are classified as follows: 270 species from 26 families of the order Lepidoptera, 61 species from 5 families of the order Diptera, 21 species from 3 families of the order Coleoptera, and 11 species from 1 family of the order Hymenoptera. The majority of species of the order Lepidoptera belongs to the families Gracillariidae (71), Nepticulidae (61) and Coleophoridae (37), of the order Diptera to the family Agromyzidae (53), and from the order Coleoptera to the families Curculionidae (12) and Chrysomelidae (7). All species of the order Hymenoptera (11) belong to the family Tenthredinidae. Monophagous and Oligophagous species are dominant among the identified species of leaf miners in Serbia. The majority of the species (57%) develop on woody plants. Most of them (30) on the species of the genus Quercus, Prunus (20), Malus (19), and Populus (19).
