| [diversity of phytophagous and pathogens and their damage to mints (mentha)]. | the aim of this work was to estimate the phytopathologic condition of mints grown and self-growing in kaunas botanical garden of vytautas magnus university and elsewhere in lithuania; and to identify the specific constitution, the spread and damage of the main pests and disease agents. material and methods: observations and examination were carried out with two local, four introduced mint species and with four hybrids in 1997-2003. we estimated the plant condition by identifying the intensity of ... | 2004 | 15299999 |
| evaluation of pheromones and a new trap for monitoring agriotes lineatus and agriotes obscurus in the fraser valley of british columbia. | a prototype ground-based pheromone trap design, baited with various pheromone lures, was field tested for effectiveness in trapping male agriotes obscurus and agriotes lineatus click beetles in british columbia. pheromone dispensers containing geranyl octanoate and geranyl hexanoate in a 1:1 ratio caught the greatest numbers of a. obscurus, whereas those containing geranyl octanoate and geranyl butanoate in a 9 or 10:1 ratio caught high numbers of a. lineatus. some differences in a. obscurus att ... | 2007 | 17191156 |
| spinosad interacts synergistically with the insect pathogen metarhizium anisopliae against the exotic wireworms agriotes lineatus and agriotes obscurus (coleoptera: elateridae). | we determined that spinosad interacts synergistically with the biocontrol agent metarhizium anisopliae (metch) sorokin to increase the mortality of two wild-collected wireworm species, agriotes lineatus (l.), and agriotes obscurus (l.). bioassays were performed using a m. anisopliae isolate originally acquired from a local wireworm cadaver. m. anisopliae was applied as a soil drench at 3.3 x 10(2) and 10(4) conidia per gram sand, respectively. soil drenches also were prepared using a commercial ... | 2007 | 17370806 |
| vegetable and animal food sorts found in the gastric content of sardinian wild boar (sus scrofa meridionalis). | authors report results emerging from gastric content analysis from n. 96 wild boars hunted in sardinia isle, during the hunting tide (2001-2005), from november to january. mean ph of the gastric content was 3.77 +/- 0.69. mean total capacity (tc) of each stomach was 1702 +/- 680 g. mean stuff ratio (cw/tc) between the content weight (cw) and stomachs tc was 0.45. food categories found in animal stomachs were: 19 categories of vegetal species (allium spp., arbutus unedo, arisarum vulgare, avena f ... | 2007 | 17516948 |
| occurrence of agriotes wireworms in austrian agricultural land. | agriotes wireworms (coleoptera: elateridae) are abundant soil-dwelling herbivores which can inflict considerable damage to field crops. in europe up to 40 species occur, differing in their ecology and pest status. their distribution in the larval stage, however, has rarely been assessed because of the considerable effort in collecting wireworms and the difficulties in identifying them to species-level. here, we examined the occurrence of agriotes wireworms in austrian agricultural land with rega ... | 2011 | 23459669 |
| climatic, edaphic factors and cropping history help predict click beetle (coleoptera: elateridae) (agriotes spp.) abundance. | it is assumed that the abundance of agriotes wireworms (coleoptera: elateridae) is affected by agro-ecological factors such as climatic and edaphic factors and the crop/previous crop grown at the sites investigated. the aim of this study, conducted in three different geographic counties in croatia from 2007 to 2009, was to determine the factors that influence the abundance of adult click beetle of the species agriotes brevis cand., agriotes lineatus (l.), agriotes obscurus (l.), agriotes sputato ... | 2015 | 26175463 |
| sequential effects of root and foliar herbivory on aboveground and belowground induced plant defense responses and insect performance. | plants are often simultaneously or sequentially attacked by multiple herbivores and changes in host plants induced by one herbivore can influence the performance of other herbivores. we examined how sequential feeding on the plant plantago lanceolata by the aboveground herbivore spodoptera exigua and the belowground herbivore agriotes lineatus influences plant defense and the performance of both insects. belowground herbivory caused a reduction in the food consumption by the aboveground herbivor ... | 2014 | 24448700 |
| effects of root herbivory on pyrrolizidine alkaloid content and aboveground plant-herbivore-parasitoid interactions in jacobaea vulgaris. | the importance of root herbivory is increasingly recognized in ecological studies, and the effects of root herbivory on plant growth, chemistry, and performance of aboveground herbivores have been relatively well studied. however, how belowground herbivory by root feeding insects affects aboveground parasitoid development is largely unknown. in this study, we examined the effects of root herbivory by wireworms (agriotes lineatus) on the expression of primary and secondary compounds in the leaves ... | 2013 | 23306864 |
| influence of climatic conditions on the distribution, abundance and activity of agriotes lineatus l. adults in sex pheromone traps in croatia. | the aims of this work were: (i) to determine the distribution and abundance of agriotes lineatus, (ii) correlate the abundance with the prevailing climatic conditions to establish how temperature and rainfall are influencing the dominance, and (iii) to determine the activity characteristics of the adults. investigations were conducted in 17 fields grouped in four regions characterized by different climatic conditions. using sex pheromone traps the most important agriotes species (a. lineatus l., ... | 2013 | 22886342 |
| new sex attractant composition for the click beetle agriotes proximus: similarity to the pheromone of agriotes lineatus. | while testing traps baited with a blend of geranyl octanoate and geranyl butanoate (pheromone components previously identified for agriotes lineatus, coleoptera, elateridae) in portugal and bulgaria, large numbers of the closely related agriotes proximus were captured. in the literature, two different compounds, (e,e)-farnesyl acetate and neryl isovalerate had previously been identified as pheromone components of a. proximus. subsequent field tests, conducted in several european countries, revea ... | 2008 | 18064523 |
| above- and below-ground terpenoid aldehyde induction in cotton, gossypium herbaceum, following root and leaf injury. | studies on induced defenses have predominantly focused on foliar induction by above-ground herbivores and pathogens. however, roots are attacked by as many if not more phytophages than shoots, so in reality plants are exposed to above- and below-ground attack. here, we report effects of foliar and/or root damage on terpenoid aldehyde accumulation in cotton (gossypium herbaceum). using hplc, we analyzed concentrations of individual terpenoid aldehydes in foliage and root tissue. in undamaged plan ... | 2004 | 15074657 |
