Abstract:

 To improve the detection and prevention of foliage browsing insects' outbreaks it is very important to reveal the forest plots, which are the most favorable for these pests.
 The aim of this research was to predict using GIS technologies the spatial dynamics of foliage browsing insects' outbreaks in the pine stands of the State Enterprise "Kreminske FHE" (Luhansk region).
 Forest inventory databases of Production Association "Ukrderzhlisproekt" were analyzed for the SE "Kreminske FHE" as of 2001 and 2011. Rating of forest plots preferences for common pine sawfly (Diprion pini

Abstract:
Insect pheromones have been intensively studied with respect to their role in insect communication. However, scarce knowledge is available on the impact of pheromones on plant responses, and how these in turn affect herbivorous insects. A previous study showed that exposure of pine (Pinus sylvestris) to the sex pheromones of the pine sawfly Diprion pini results in enhanced defenses against the eggs of this sawfly; the egg survival rate on pheromone-exposed pine needles was lower than that on unexposed pine. The long-lasting common evolutionary history of D. pini and P. sylvestris suggests that

The study was carried out to evaluate the possibilities to control the common pine sawfly Diprion pini L. with the use of plant protection products Mospilan 20 SP (20% acetamipryd) and Trebon 30 EC (300 g etofenprox/l). Aerial insecticide treatments were applied onto experimental plots (100 ha) in Scots pine stands, sprayed with approximately 3 l of spray solution/ha. Mospilan 20 SP at a rate 0.20 kg/ha caused 61%-76% mortality of D. pini larvae, whereas at a rate 0.25 kg/ha – 100% larval mortality. Trebon 30 EC aerial treatments at a rate 0.2 l/ha resulted in 100% larval mortality. Stud

Сосну крымскую всё чаще стали вводить в культуры в некоторых регионах юга России, в частности в Ростовской области. В междуречье Дона и Волги естественные сосняки отсутствуют, но уже более 100 лет здесь создают искусственные посадки этой породы. Здесь часто и на больших площадях формируются очаги массового размножения рыжего соснового пилильщика. Первые посадки сосны крымской показали, что этот вредитель не повреждал ее, отдавая предпочтение сосне обыкновенной. Это стало причиной того, что сосну крымскую все чаще стали высаживать на лесокультурные площади. К настоящему времени в Шолоховском ле

A significant decrease in the frequency of reproduction outbreaks of certain types of needle- and leaf-eating pests was shown, which corresponds to the trends for some other regions. For the pine looper (Bupalus piniaria (L.)), the pine beauty (Pannolis flammea), the buff-tip (Phalera bucephala (L.)), the rusty tussock moth (Orgyia antiqua (L

Abstract Pine sawflies (Hymenoptera, Symphyta, Diprionidae) are the most spread foliage browsing insects of pine forests in Europe, especially monovoltinous European pine sawfly Neodiprion sertifer (Geoffroy, 1785) and common pine sawfly Diprion pini (Linnaeus, 1758), which develops in one or two generations per year depending on weather. The outbreaks of both pine sawflies are the most frequent and intensive in the Steppe zone of Ukraine, especially in the Low Dnieper region, where pine forest (Pinus sylvestris Linnaeus and Pinus pallasiana D.

Abstract To estimate the impact of a single spring defoliation by loblolly pine sawfly (Neodiprion taedae linearis Ross), diameters of 3,006 loblolly pines from five locations in southeastern Arkansas were measured immediately after defoliation and two more times at 1-year intervals.The proportion of defoliation was assessed at each measurement. An insecticide was used in an attempt to prevent defoliation in subsequent years. Because tree growth depends on many factors, a multivariate multiple regression model was used to separate these effects. The model predicts thata single defoliation redu

Abstract:
Abstract Low-alloy steel of API 5L grade X65 is commonly used as line pipe material for sour service applications. Within recent years more challenging requirements have been introduced, including more severe corrosion test conditions, increased mechanical properties, and extended limitations regarding hardness, to enable application to increasingly severe sour service conditions. Within this study a systematic investigation of material properties related to corrosion resistance was performed for low sulfur X65 TMCP-based steel plates with a thickness of 30 mm and 35 mm.
