  The saw-toothed grain beetles, Oryzaephilus surinamensis L. (col., Silvanidae) is one of the most important pests that damage to stored products in Iran. The efficacies of three IGR insecticides, Tebufenozide, Chromafenozide and Lufox® have been evaluated on eggs an More

  The saw-toothed grain beetles, Oryzaephilus surinamensis L. (col., Silvanidae) is one of the most important pests that damage to stored products in Iran. The efficacies of three IGR insecticides, Tebufenozide, Chromafenozide and Lufox® have been evaluated on eggs and larval stages of O. surinamensis during this study. The Efficiencies of these  insecticides have been  considered by different concentrations on one day old eggs, 5 day old (young) and 19 day-old  larvae. The results of bioassay tests showed that Lufox® has the most and Tebufenozide has the least efficacy on eggs and larval stages. Also, the mortality effects directly increased by raising the IGRs concentrations. In the other aspect, the eggs of O. surinamensis were the most susceptible stage in response to IGR insecticides. The LT50 value of Lufox® was shorter than that of Tebufenozide and Chromafenozide. Finally the high toxicity and strongest efficiency can be resulted by using of Lufox® in comparison with Tebufenozide and Chromafenozide. Manuscript profile

  Batrachedra amydraula (Ba) is one of the most important date pests in Khuzestane province. In this research cluster sampling method was carried out for studying the geostatistical models of its distribution during 2002-2005. Sites of sampling (including 65 plots) were distributed from 25.59 to 32.08 geographical longitudes and 48.8 to 50.1 geographical latitude in Khuzestane province. Variography of distributions on different sites were studied based on Spherical, Exponential, Linear, Linear to sill and Gaussian models and their Kriging maps were drawn. Results showed that the best model for the pest was Exponential. Nuggets were 0.52, 0.43 and 0.47 for three years, respectively. These results showed that bias of the pest damage estimation was low at the distances less than whithin sampling space. Effective ranges of variograms were 239.5, 228.2 and 354.8 kilometers for three years respectively. The data indicate that the mean damages of the pest are not correlated at more than these distances. Sill of models were 1.047, 0.855 and 1.152  for three years respectively which indicated that the population distribution in the region. Results of this research confirmed that the geostatistic method was a precise sample and low cost for evaluating the pest damage in integrated pest management. Manuscript profile

  The success of any raw material used in the industrial and mass production of entomopathogenic fungi depends on the extent to which it can provide the optimum food requirement for the fungus. The biological control strategy using entomopathogenic fungi like B. bassiana and M. anisopliae can only be useful if practical and economic methods of mass multiplication are available. In this study, the effects of Protein and Vitamins Supplements on chlamydospores production of these two fungi were investigated. The results of this study showed that different treatments of Protein and Vitamins Supplements in complete liquid culture for chlamydespore cycle of B. bassiana and M. anisopliae fungi in terms of production spores, germination percentage, wet weight and dry weight difference Significant at 1% probability level. The highest concentration of chlamydosporum, germination percentage, wet weight and dry weight of B. bassiana and M. anisopliae were whey protein supplement and multivitamin at a concentration of 6 ml / liter. Also, the results of this study showed that these two species of pathogenic fungus can be replicated with good performance of sugarcane by products and maintain the germination capacity of chlamydospores.

  Several sampling techniques including sweeping net, D-Vac traps for adults and three different methods of nymph counting (direct count, leaf washing and suction method) were compared in two vineyards in Isfahan, in 1996-1997. Adult grape leafhopper were sampled weekly by sweeping net (10 sample per vineyard) and D-Vac apparatus (10 samples per vineyard each sample unit consisted of 3 minutes suction). Number of nymphs was recorded weekly on leaves. Sample unit was three leaves per tree taken from three strata in the vine canopy of 10 trees. Two parameters including relative variation (RV) and relative net precision (RNP) were used for comparing the sampling methods. Results showed that the best duration time of sampling unit to catch adults was 120-180s by D-Vac. Sweeping net (RV= 18.87 and RNP=2.88) was more suitable than D-Vac in IPM sampling program for the method using D-Vac apparatus. D-Vac was more suitable for studying the adult population fluctuations because of a minimum RV during the season. But its sampling costs was more than other methods. Washing method (RV= 2.9 and RNP= 13.3) was more suitable than direct counting and vacuum in IPM sampling program for nymphs. All three methods were suitable for ecological studies of nymphs but their efficiencies were different for different nymph instars. Manuscript profile

  Arboridia Kermanshah Delabola (Hem., Cicadellidae) is a dominant species of leafhoppers in vineyards of Isfahan, central region of Iran. The most abundant parasitoid of the leafhopper is Anagrus atomus in the region. This research was conducted to study the effects of the spatial distribution and density of the parasitoid and host on searching efficiency of parasitoid and parasitoid-host stability. Results showed a significant difference between host and parasitoid distribution on arms of vine trees. The highest density of parasitized and non-parasitized eggs of the leafhopper eggs were observed on leaves 7-12 in the middle of each vine arm. There was a significant density dependent relationship between host and parasitoid. Studying on the host and parasitoid density relationship showed that a high searching efficiency was observed in the first generation of host when the parasitoid density is low. The parasitoid searching efficiency was decreased by increasing the parasitoid density. When the parasitoid was leaving vineyard for wintering, the searching efficiency increased with decreasing in  number of parasitoid. Interference coefficient (m) was higher when the parasitoid-host ratio was high and the searching efficiency decreased in this condition. The value of m was close to Q (searching constant) when the parasitoid-host ratio was high and host- parasitoid relationship was more unstable. Manuscript profile

  Oryzaephilus surinamensis L. (Col., Silvanidae) is one of the most important stored product pests in Iran. Regarding to environmental risks of pesticides, scientists are exploring substitute compounds with less hazard to man and environment, such as RGRs. The purpose of this project is to evaluate the efficacy of three IGR insecticides, Tebufenozide, Chromafenozide and Lofux® with two methods of oral and contact on O. surinamensis larvae in laboratory condition. Different concentrations of the above insecticides have been used on 4-5 (young) and 19-20 day-old (old) larvae. Bioassay tests showed that in oral method Lufox (LC50 =9.68) and Tebufenozide              (LC50 =24.49) had the most and the least efficacy on young larvae, respectively. Lufox                  (LC50 =22.82) and Tebufenozide (LC50 =80.18) had also the most and the least efficacy on old larvae, respectively. The most and the least efficacy contact method, on young larvae have been induced by Lufox® (LC50 =1) and Tebufenozide (LC50 =33.9), respectively. Lufox (LC50 =29.2) and Tebufenozide (LC50 =143.03) had the most and the least efficacy on old larvae, respectively. Based on the results obtained, the use of oral method was more effective than useing contact method. Lufox® is a mixture of chitin synthesis inhibitor and juvenile hormone mimic. This combination showed the best performans on larvae O. Surinamensis and can be used safely for controling the pest. Manuscript profile

  Oligonychus afrasiaticus (McGregor)is an important date palm pest orchard in Iran and other date growing in the world. Direct mite incidence along feeding on date fruit caused 100% losses on commercial date varieties. Chemical date palm spider mite (DPSM) control initiated in 1960 in southwestern part of Iran through Tetradifen application and today extended in large date orchards in the country. Water spray application on DPSM under taken through block randomized designed with four replications during period of 2000-2001 on date varieties i.e. Mordarsangh, Kabkab, Berhi, Mazafati, Halileh in Hormozghan, Bushehr, Khuzestan, Kerman and Sistan and Baluchestan provinces of Iran respectively. Amount of 8 to 10 little water spray with help of concern instrument during late morning hours. The mobile mite mortality% was evaluated through Henderson–Tilton method by collecting 20 date fruits which two date clusters selected randomly from each replication and counted with help of stereo-microscope. Mite sampling followed at interval of one day before, 3, 7, 14 and 25 days after treatments. Light copious webbing around date clusters observed in late April in Kuzestan province and this type of injuries recorded after three months interval (July) on date palm's of Sistan and Baluchestan provinces in south eastern part of country. Mean date palm infested by DPSM was found higher in year of 2001 in comparison of the first year study. Max & min mean of mites' densities on a date fruit recorded 14.9 and 2.08 mites on Kabkab and Berhi var. in Bushehr and Kuzestan respectively while Halileh var. in Sistan and Baluchestan province possess higher number of mite during two years of investigation. Mean of mite mortality% statistically observed significant at level of 5% during sampling period with maximum control of mite at seven days interval whereas longer effects of water spray recorded up to 25 days in Kerman province. Two years mite mortalities% analysis result over 90% mite control in date orchards of Khuzestan, Hormozgan and Kerman provinces during first and second year respectively. Max water spray effect can expected when mean of mite on a date fruit was recorded below three mites with three consequent spray at 7 to 10 days interval which make possible organic date production in Iran with regard further mite resistance and hazardous of pesticides to the environment.

  Various biotic and abiotic factors induces stress to the plant. Climatic changes, monoculture systems and irregular use of chemical pesticides affect pests and their natural enemies in the date palm agricultural ecosystems. Date palm pests are initially an ecological problem rather than a chemical problem, so unprincipled use of costly chemical pesticides is a failed strategy. Biological control is the backbone of the integrated pest management program which is based on three control methods including cultural control, resistant cultivars and chemical control (in compulsory conditions) are incorporated by that. Augmentation biological control has been done by inoculated release of Coccinelid predator Stethorous gilvifrons, Bacillus thurengeinsis and Metarhizium anisopliae against date palm spider mite, the lesser date moth and long horned beetle respectively. Date production efficiency can be increased by implementing the advanced cultural control practices. The correct enforcement of cultural control such as tillage, fertilization, irrigation and bunch management reduce date palm pest damages. The susceptibility of the date palm cultivars also effect the performance of integrated pest management programs. As a supplementary step a number of specific pesticides are recommended in integrated pest management of date palm. One of the most important problems of date palm pests control is accurate decision making system including forecasting and monitoring. A substantial and rapid change is necessary in order to achieve the ecological and economic approach of date palm pest control. Manuscript profile
