Determination of Egg Laying Character of Phenacoccus Aceris (Signoret) (Hemiptera: Coccoidea: Pseudococcidae) on Different Host Plant Species
(Ankara Univ, Fac Agr, 2007) Kaydan, M. Bora; Kilincer, Neset
Egg fecundity and hatching time of Phenacoccus aceris (Signoret) were investigated in 2002 and 2003 on tree different host plant (Fraxinus excelsior L., Acer negundo L. and A. pseudoplatanus L.). It was determined that P. aceris individuals feeding on F excelsior laid more eggs than other two host plant (766.45 eggs on F. excelsior, 484.06 eggs on A. negundo and 638.82 eggs on A. pseudoplatanus in 2002, respectively 870.73, 663.54, 552.73 eggs in 2003). Most of eggs were laid in the first week of the oviposition period and almost all of the eggs were laid first couple weeks of the oviposition period of P. aceris on all tree different host plants. Hatching time of the eggs laid by maple mealybug fed on different host plant ranged 21 to 24 days.

Effects of Some Fungicides on Isaria Farinosa, and in Vitro Growth and Infection Rate on Planococcus Citri
(Springer, 2011) Demirci, Fikret; Mustu, Murat; Kaydan, M. Bora; Ulgenturk, Selma
The effects of some fungicides used against citrus diseases, on mycelial growth and conidial germination of Isaria farinosa (Holmsk.) Fries [Sordariomycetes: Hypocreales] and also on the pathogenicity of the fungus on citrus mealybug, Planococcus citri (Risso), were determined. Systemic fungicides such as tebuconazole, penconazole and nuarimol were the most effective as regards both conidial germination and mycelial growth. Protective fungicides such as captan, chlorothalonil, mancozeb and propineb inhibited conidial germination at between 1 and 5 mu g ml(-1) concentration, but captan, chlorothalonil and propineb did not inhibit the mycelial growth at 5,000 mu g ml(-1). Mancozeb inhibited mycelial growth between 2,500 and 5,000 mu g ml(-1). Sulphur and copper oxychloride did not inhibit the fungus even at very high concentrations. Sulphur, copper oxychloride, fosetyl-al, chlorothalonil and carbendazim did not decrease the mortality percentage caused by I. farinosa. Tebuconazole, penconazole and mancozeb were the most effective and respectively reduced the mortality from 83% to 33%, 28% and 30% in the ovisacs, from 81% to 29%, 27% and 29% in the 1st instar larvae, and from 84% to 34% in the adult females.

Two [Aleurochiton acerinus Haupt, Dialeurodes kirkaldyi (Kotinsky)] were new records for the Turkish fauna among the totally 8 species determined in the Region. Their identification, host plants, and distribution in Turkey and in the world were presented as detailed.
Functional Response of the Coccinellid Predator Adalia Fasciatopunctata Revelierei To Walnut Aphid (Callaphis Juglandis)
(Springer, 2010) Atlihan, Remzi; Kaydan, M. Bora; Yarimbatman, Alper; Okut, Hayrettin
The functional response types and parameters of 3rd and 4th instar larvae, and adult females and males of a coccinellid predator, Adalia fasciatopunctata revelierei (Mulsant) (Col.: Coccinellidae), were evaluated at five different densities of Callaphis juglandis (Goeze) (Hemiptera: Aphididae) in order to understand their role for the aphid's biological control. Experiments were carried out in petri dishes at 25 +/- 1 degrees C, 60 +/- 10% r. h. and 16L:8D photoperiod in a controlled temperature room. All tested stages exhibited a Type II response determined by a logistic regression model. The attack rate (alpha) and handling time (T-h) coefficients of a Type II response were estimated by fitting a "random-predator" equation to the data. Although the estimates of alpha for all stages of A. fasciatopunctata revelierei tested were similar, the longest T-h was obtained for 3rd instar larva because of the lower consumption rate at densities above 40 prey/day. Results indicated that the adult female has the highest predation of C. juglandis followed by 4th instar larvae, adult males and 3rd instar larvae. However, further field-based studies are needed to draw firm conclusions.

(Entomological Soc Turkey, Ege Univ, 2011) Atlihan, Remzi; Ozgokce, M. Salih; Kaydan, M. Bora; Kasap, Ismail; Kilincer, Neset; Kiyak, Suat; Polat, Evin
This study was carried out to determine insect pests and their natural enemies in walnut orchards in Van lake basin in 2005-2006. Steiner funnel, visual observation and rearing method were used for samplings. As a result, 29 phytophagous species belonging to 11 different families and 21 beneficial insect species belonging to 6 families were determined. It was observed that Cydia pomonella (L., 1758) (Lepidoptera: Tortricidae) was the economically important pest, and Panaphis juglandis (Goeze, 1778) (Hemiptera: Callaphididae) had remarkable population level. Chrysoperla carnea (Stephens, 1836) (Neuroptera: Chrysopidae) and Adalia fasciatopuncata revelierei (Mulsant, 1866) (Coleoptera: Coccinellidae) were the most common and widely distributed species among natural enemies obtained.

Investigations on Some Biological Characters of Pseudococcus Cryptus (Hempel) (Hemiptera: Pseudococcidae) on Four Citrus Species
(inst Zoology, Bas, 2014) Holot, Didem; Kaydan, M. Bora; Mustu, Murat
The developmental time, longevity, fecundity, sex ratio, duration of preoviposition, oviposition and postoviposition, number of nymphs and life table parameters of Pseudococcus cryptus (Hempel) (Hemiptera: Pseudococcidae) were studied on four citrus (Rutaceae) species (Citrus paradisi, C. limon, C. unshiu, C. sinensis), in an acclimatized room at 25 +/- 2 degrees C, 60-70% relative humidity and 14:10h (1:d) photoperiod. The results suggest that some of the parameters for P cryptus populations were affected by the species of citrus, and that C. limon was the preferred host plant. The population parameters on C. limon were determined as r(m) = 0.1526 d(-1); R-0= 65.8 offspring/individual and T-0 = 27.4 days.
Laboratory Evaluation of the Effectiveness of the Entomopathogen; Isaria Farinosa, on Citrus Mealybug, Planococcus Citri
(Springer Heidelberg, 2011) Demirci, Fikret; Mustu, Murat; Kaydan, M. Bora; Ulgenturk, Selma
Citrus mealybug Planococcus citri (Risso) (Hemiptera: Pseudococcidae) is one of the main pests on citrus trees. Biological control of the pest is based on the release of hymenopterous parasitoids and coccinellid predators at present. The effectiveness of entomopathogen fungus Isaria farinosa (Holmsk.) Fries ([Sordariomycetes: Hypocreales] (Syn: Paecilomyces farinosus), as an alternative biological control agent on citrus mealybug, was investigated using four different inoculum densities and different relative humidities (RH). The entomopathogen caused 89.39% mortality in ovisacs, 84.07% mortality in second larval stage, 84.53% mortality in adult females, and 78.71% mortality in first larval stage at 95% RH and at 1 x 10(8) conidia ml(-1) inoculum concentration. Percent mortalities were between 50 and 60 in ovisac, first and second larval stage at 95% RH and at 1 x 10(7) conidia ml(-1). Percent mortality was decreased parallel to the decrease in humidity level and inoculum densities; however, the fungus caused significant infection in 70% and 80% RH. These results demonstrated that the effectiveness of the entomopathogen is promising for biocontrol of citrus mealybug.
Modeling Insect-Egg Data With Excess Zeros Using Zero-Inflated Regression Models
(Hacettepe Univ, Fac Sci, 2010) Yesilova, Abdullah; Kaydan, M. Bora; Kaya, Yilmaz
As zero-inflated observations occur very often in studies on plant protection, models taking into account zero-inflated observations are frequently required. Especially, zero-inflated observations occur in large numbers for insects whose post-oviposition period lasts long, or that generally lay their eggs during the first clays of the oviposition period. For the data used in this study, 1114 (43.84%) of the 2541 observations were zero. In the selection of an appropriate regression model, zero-inflated negative binomial regression was chosen as the best model. In all regression models, the day of laying and the three different hosts were seen to have a significant effect on daily egg numbers (p < 0.01).
Molecular Phylogeny and Species Recognition in the Mealybug Genus Ferrisia Fullaway (Hemiptera: Pseudococcidae)
(Wiley, 2010) Gullan, Penny J.; Kaydan, M. Bora; Hardy, Nate B.
Previous allozyme and DNA nucleotide sequence studies of the mealybug genus Ferrisia Fullaway (Hemiptera: Pseudococcidae), although limited, have suggested greater species diversity than is recognized by the current morphology-based taxonomy. Here we analyse nucleotide sequence data from one mitochondrial (cytochrome oxidase I) and two nuclear (EF-1 alpha and 28S D2D3) genes and recover ten well-supported groups that allow us to reassess the taxonomic utility of morphological characters used for species recognition. We report on previously used morphological characters for which states are highly variable within genetic groups and identify new characters (of the wax-exuding cuticular ducts and pores) with taxonomically informative states. The widespread pest species F. virgata (Cockerell), commonly called the striped mealybug, should be diagnosed more narrowly. From samples identified as F. virgata, we recover six clades that we equate with species and that can be distinguished with the newly identified morphological characters. We determine that five of the 'electrophoretic species' identified informally by the late Uzi Nur based on electrophoretic mobility of 20 enzymes correlate with four of our genetic groups. This matching of Nur's putative species with ours was possible only because some of Nur's slide-mounted voucher specimens were deposited in a museum and thus available for morphological study. Species confused with F. virgata are either new to science or were placed erroneously in synonymy with F. virgata by earlier authors: they will be described elsewhere. The most important characters of the adult female for distinguishing these species from F. virgata are the positions and characteristics of minute discoidal pore(s) associated both with the ventral oral-collar tubular ducts and with the sclerotized area surrounding each dorsal enlarged tubular duct, and the number of sizes of the ventral oral-collar tubular ducts. In addition, we determine that adult females of F. gilli Gullan from different populations on different host plants vary substantially in the number and size of clusters of small ventral oral-collar ducts on the body margins - features previously suspected to indicate distinct species.

(Entomological Soc Turkey, Ege Univ, 2009) Kasap, Ismail; Atlihan, Remzi; Ozgokce, M. Salih; Kaydan, M. Bora; Polat, Evin; Yarimbatman, Alper
The aim of this study was to determine the population densities of pest and important predatory mites in the walnut orchards of around Van Lake. The study was conducted in five walnut orchards in the Adilcevaz county in Bitlis (three orchards) and Gevas county in Van (two orchards), during the growing seasons of 2005-2006. Surveys were carried out in every week from May to November. The results of study indicated that the population densities of mites began to increase generally in early July, reached the maximum level at late July and at early August and preserved to late October. In this period, the population densities of Aceria erinea Nalepa (Acari: Eriophyidae) and Eotetranychus carpini (Oudemans) (Acari: Tetranychidae) were determined as 51.9 galls/leaf and 304.1 mites/leaf, respectively. Euseius finlandicus (Oudemans) (Acari: Phytoseiidae) was the most effective predatory mite on E. carpini and A. erinea and it was observed that its population reached to 4.5 mites/leaf. In the sprayed orchard, E. finlandicus population was not enough for controlling mites and the population densities remained at very low levels.
