Melanophila picta Pall. is spread through a great part of Turkey. Plantations are attacked the most widely in their first years. Sometimes old plants are also attacked. Meteorologic conditions play a great role in that attack. For example, the attacks are more in hot and dry regions. On the contrary in humid regions, the attack decreases. In the Marmara region cultural procedures are sufficient to prevent the attack. According to the geographic regions, the biologic phases of the insect changes. For the resolution of that problems a research project is prepared. The egg of M.picta Pall. firstly observed in the project period. The egg that is white when it is laid off changes its color to the color of the trunk it is laid in two hours. The duration of the hatching of the eggs are 9-10 days. The mouth parts and the segments of the thorax of the early burnt larvae are perfectly formed. There are some bunches of bristles on the segments of the abdomen that supply the first movement of the larvae and full down afterwards. According to the spots on anterior wings there are several varieties of that insect.


2) THE COMPARISION OF THE ENDURANCE AGAINST THE ATTACK OF Melanophila picta Pall. IN THE PLANTATIONS ESTABILISHED WITH THE SAMPLING OF ONE YEAR AND TWO YEARS OLD

The attack of M.picta Pall. is dangerous especially in the firsts year of the plantation. In dry and hot climatic regions, in spite of the cultural procedures, the attacs continue. In that regions the application of chemical strriggle and prevention methods are expensive and difficult. It was thought that the plantations of first years plants are more resistant. It was concluded that, it is suitable to employ first year plants in South, South East and West Anatolia plantations in spite of all cultural precautions.


3) SOME INVESTIGATIONS ON THE BIOLOGY OF Capnodis mliaris Klug. AND OTHER Capnodis sp.

Authors: KARAGOZ, O., SEKENDIZ, O.

This insect is a nuisance in South, South East and West Anatolia. A research project is planned to investigate its local biology. In this article the summary of the first year investigations are presented. Capnodis miliaris Klug. lays its eggs during the period from the beginning of June to the end of August. It leaves its eggs on the earth in to the fissures of the soil. The generation of that insect is two years. The duration of the hatching of egss 12-13 days. By the increase in the humidity, the death of the eggs is increases. According to our experiments, by means of the irrigations andworkings on soil performed once in 10 days, the percentage of attack is diminished to 0.5. By the application of the some technique the attack of that insect was prevented absolutely after 1965, at the substation in Torbali.


4) SOME INVESTIGATION ON THE BIOLOGY OF Sciapteron tabaniformis Rott.

Year /Number:1967/2                             ODC: 145.7:18.06:176.1. Populus
Authors: KARAGOZ, O., SEKENDIZ, O.

This insect is spread out through all regions of Turkey. It is a great nuisance frequently in the plantations in Middle and South east of Anatolia. Its biology changes according to the geographic regions of Turkey. For the application of chemical and other struggle metdods, it is necessary to comprehand the local biology of this insect. The duration of the research project on the biology of Sciapteron tabaniformis Rott. is three years. The interesting results of the first year works are demonstrated as follows. Sciapteron tabaniformis rott. lays its eggs from the beginning of May to end of July. Generally, it lay its eggs at 1.5-2 m above the ground but in the environment of Diyarbakir, the attacj even at 6 m above the ground are observed. There are some caterpillar parasites that prevent the maturation of chrysalides. But parasited caterpillars continue their destructions. According to geographic regions the types of parasites and their percentage of attack varies.


5) SOME INVESTIGATION ON THE GEOPRAFICAL DISTRIBITION AND THE BIOLOGY OF Agrilus sp. THAT CAUSE HARM IN THE ENVIRONS OF THE REGIONS OF MARMARA AND THRACE

Authors: KARAGOZ, O., SEKENDIZ, O., VURAL, M.

The attack of that insect is observed in Marmara and Thrace regions, in the plantations of six years old. On tthe attacked trunks some spots and liquid flows are observed in the environment of the attacked region some concavities that spoil the from of trunk are formed. To investigate teh causes of that disease, a research project is prepared. In the article authors represent the results obtained at the end of the first year. The adults of that insect are obtained at 4/6/1967 in Izmit. According to our determination it is Agrilus ater L. The egg packages are deposited on the trunks by females of the insect. These packages are white. Its larvae form some sinusoidal channels in the cambium region, larvae leave in the bark during the winter. During H.C.H. the observation of spots and liquid flows, the injection of insecticides, to the diseased was performed good results. Acording to our investigations, the attack of Agrilus ater L. are observed in the plantations on heavy and bad drained soils.


6) THE FUNGI ATTACKING POPLARS IN TURKEY

Year /Number: 1967/2                             ODC: 443.3:172.1:176.1. Populus
Authors: KARAGOZ, 0., VURAL, M.

The purpose of this inventory project that deal with the identification of fungi on the poplars planted in several climatic regions of Turkey, is to fix the poplar fungi flora. In the following years as a result of this works, the fungus flora of Turkey that remained empty up to that date will be fixed. Within the framework of this project, some fungi species identified and a list of the most important species were shown as follows : Marssonina Sp. Drepanopeziza Sp. Oidium Sp. Uncinula salicis (D.C.) Wint. Septoria populi Desm. Mycosphaerella populi (Aursw.) Kleb. Pollacia radiosa (Lib.) Bald. et Cif. Cladosporium epiphyllum (Pers.) Mart. Phoma Sp. Scleroderris Sp. Polyporus Sp. Cytospora chrysosperma (Pers.) Fr.


7) SOME INVESTIGATIONS ON THE STUDY OF Taphrina aurea (Pers.) Fr. AND ON THE CHEMICAL CONTROL AGAINST THE DISEASE CAUSED BY THIS FUNGUS THAT ATTACKS P. x. euramericana (Dode) Guiner. Cv. I-214 IN NURSERY UNDER THE CLIMATIC CONDITIONS OF THE REGION OF MARMARA

Authors: KARAGOZ, O., VURAL, M.

Very little work is performed on Taphrina aurea (Pers) Fr. which is taken into consideration in Izmit Poplar Institute up to that day. According to our investigations that parasite which is especially destructive in nursery gardens, plays its destructive effect by causing hypertrophie in palisatic paranchime in tissue of leaves and the decreasing of assimilation of chlorophyll. The project is considered in two sections. In the first part researches about the biology of parasite are made. On the other hand it is fixed the disease comes out at the end of April, under the climatic conditions of Izmit. It is also fixed that disease destroys, only two years old P.x euramericana (Dode) Guinier cv. "I-214" plants. The second part of that project which was the chemical control, couldn't out.


8) SOME INVWSTIGATIONS ON THE STUDY OF Septoria sp. AND THE CHEMICAL CONTROL AGAINST THE DISEASE CAUSED BY THIS FUNGUS THAT ATTACKS LEAVES OF SAPLING OF P. x. nigra Tr. Cv. 56/52

Authors: KARAGOZ, O., VURAL, M.

The poplar which has a great use day is attcked by some destructive fungi after being-cu off. They cause the wood is spoiled. Because of that reason it is necessary to make research for the identification of the enemies of the wood after being cut-off. This researches will supply a basis for the works to destroy them in struggling. The fungi that destroy the poplar wood are mentioned here. Within the framework of this project, some fungi species which infest the piled poplar wood were diagnosed and a list of these fungi were shown as follows : Polyporus versicolor (Linex Fr.) Pilat. Polyporus hirsitum Schrad. Polyporus sulphureus (Bulliard ex Fries) Karst. Schizophhillum commune Fr. Stereum purpureum (Pers. et Fr.) Fr. Pholiota destruens (Brond) Fr. Pleurotus ostreatus (Jacquin et Fries) Quelet. Cytospora chrysosperma (Pers.) Fr. Tricothecium roseum (Bull.) Lk.


10) THE EXPERIMENT WITH SOME INSECTISIDES FOR Melanophila picta Pall. TO PROJECTS THE PLANTATIONS OF ONE YEAR OLD I-214

It is a sufficient measure in practice to apply systematical insecticides with brush on the lower two meters part of the stems the infestations of M. picta Pall. But this application should be repeated at intervals of 15 days during the vegetation period. With another experiment we have also determined that the larvae which are under the bark and within the cambium could be killed with the some application of insecticides. Even if it is supposed that the minumum period is 15 days during which the isecticide is effective, a larvae coming out of egg laid at the end of scond application which would occure at the end of second application which would occur at the end of this period would be sufficient to solve the problem. The experiments were carried out with three different doses in three different climatical regions of Turkey. All the doses applied were successful in Diyarbakir and in Izmit, but none of them was sufficient in Torbali. therefore it could be stated out as a result that t is a sufficient control measure for M. picta Pall. to apply the insecticides once a month for the stations of Izmit and Diyarbakir. But for the Aegean region the spray should be repeated at ntervals of 15 days for the present and experiments with some other insecticides which keep their effectiveness for a longer period of time should be carried out.
