“…They also stated that the crop has tremendous ability to tiller and compensate for poor stands, so planting density is not as important compared to other crops that do not have the ability to tiller. Cherry et al (2013) found little to no correlation between sweet sorghum M81-E planting density and damage by E. lignosellus. Therefore, stands reduced by E. lignosellus damage may be at least partially compensated for by increased tillering.…”

“…Henderson et al (1973) indicated that E. lignosellus was an economically important pest of sweet sorghum in Mississippi where severe damage to main stalks and new shoots reduced stand and yield. Damage to emerging sweet sorghum shoots by E. lignosellus reached 26% in M81-E planted 22 Mar 2011 at Belle Glade, Florida (Cherry et al 2013). We are not aware of economic threshold levels published for E. lignosellus on sweet sorghum.…”

“…In a study on the effect of different cultural and control practices on the infestation of different insect pests on cabbage, a higher density had lower infestation [51]. Fall armyworms Spodoptera frugiperda Smith, and the lesser cornstalk borer Elasmopalpus lignosellus Zeller showed no correlation with the density of sweet sorghum Sorghum bicolor Moench [52].…”

Date palm trees, Phoenix dactylifera, are the primary crop in Oman. Most date palm cultivation is under the traditional agricultural system. The plants are usually under dense planting, which makes them prone to pest infestation. The main pest attacking date palm crops in Oman is the Dubas bug Ommatissus lybicus. This study integrated modern technology, remote sensing and geographic information systems to determine the number of date palm trees in traditional agriculture locations to find the relationship between date palm tree density and O. lybicus infestation. A local maxima method for tree identification was used to determine the number of date palm trees from high spatial resolution satellite imagery captured by WorldView-3 satellite. Window scale sizes of 3, 5 and 7 m were tested and the results showed that the best window size for date palm trees number detection was 7 m, with an overall estimation accuracy 88.2%. Global regression ordinary least square (OLS) and local geographic weighted regression (GWR) were used to test the relationship between infestation intensity and tree density. The GWR model showed a good positive significant relationship between infestation and tree density in the spring season with R 2 = 0.59 and medium positive significant relationship in the autumn season with R 2 = 0.30. In contrast, the OLS model results showed a weak positive significant relationship in the spring season with R 2 = 0.02, p < 0.05 and insignificant relationship in the autumn season with R 2 = 0.01, p > 0.05. The results indicated that there was a geographic effect on the infestation of O. lybicus, which had a greater impact on infestation severity, and that the impact of tree density was higher in the spring season than in autumn season.

“…Most experimental results show that the density of herbivores per plant decrease with increasing density of host plants (Neumann and Ulber 2006;Rodriguez et al 2012;Halpern et al 2014). Only a few experiments supported the opposite eff ect (Ralph 1977;Fischer and Ulber 2006), and some experiments did not detect consistant results (Neumann and Ulber 2006;Cherry et al 2013). In the presented trials the tendency was for *sowing seed density; **means followed by diff erent letters for particular dates are signifi cantly diff erent (ANOVA, p ≤ 0.05) fl ea beetle numbers to increase with decreasing plant density.…”

Linseed, one of the oldest cultivated crops, is again gaining in importance, mainly due to its nutritional benefi ts and biomedical applications. Th erefore, it is expected that herbivores will also exist in greater abundance. Among them the fl ea beetle, Aphthona euphorbiae Schrank and Longitarsus parvulus Paykull are considered to be serious pests of fl ax grown for fi bre and seeds in Europe. Th e aim of this study was to determine fl ax fl ea beetles' abundance, species richness and seasonal dynamics on linseed grown at diff erent densities. It was expected that linseed seeding density can signifi cantly aff ect fl ea beetle populations. Th e experiment was carried out in Lower Silesia, Poland, from 2011 to 2013. A genetically modifi ed type of linseed overproducing fl avonoids was used. Flea beetles and the damages they caused were determined on plants and also a sweep net was used for the collection of adult beetles. During the three years of the study 15 species of fl ea beetles were identifi ed from oil fl ax plants, with A. euphorbiae and L. parvulus being dominant. In terms of the total catch, the tendency was for beetle numbers to decrease with increasing plant density. Flax fl ea beetles feeding on linseed plants, irrespective of plant density, had two peaks of abundance. Th e fi rst peak was lower and occurred in June, when plants were at the blooming stage. Th is peak was caused by overwintering adults who colonized crops in spring. Th e second, higher peak of abundance was recorded in the second half of July, when plants were at the ripening stage. Th is peak was formed by adults of the new generation. Each year, at the higher population peak of abundance, the fl ea beetles were most numerous on plants grown at the lowest density. Th ere was one period, lasting either from mid-May to the fi rst few days of June, or from the beginning of June to mid-June, during which the number of holes and damage on plants of each treatment were highest. During the three years of the study there were several cases of signifi cantly higher numbers of fl ea beetle feeding symptoms on plants grown at the lowest density as compared to the medium and highest densities.
