Generalist predators, such as spiders, ants and ladybirds, occurred on the willows but were never observed attacking the eggs.From theCambridge English Corpus
In the present study, there were severalwillowstands with relatively low densities of both heteropteran predators and leaf beetles.From theCambridge English Corpus
With extensivewillowbeds this method of control presents some difficulty, since only part of the crop could be handled in the period suggested.From theCambridge English Corpus
The maximum difference between observed and predicted survival inwillowstands was 0.053, indicating a reasonably good model fit.From theCambridge English Corpus
A courtyard opens out, with awillowtree, and a bonsai pine.From theCambridge English Corpus
Forest willows are surrounded by many trees and, thereby, many possible over-wintering sites.From theCambridge English Corpus
The predator was more abundant on farmland willows and is probably the main reason for the difference in egg survival between the two habitats.From theCambridge English Corpus
The moss was burnt off thewillowstocks and in some cases the heat discoloured and even damaged the bark of the stocks.From theCambridge English Corpus
Infestation was also reduced by burning waste hay over the rows ofwillowstocks during the dormant season.From theCambridge English Corpus
In each of the 20willowstands, four cages containing two males and two females were placed on randomly selectedwillowbranches.From theCambridge English Corpus
All willows were growing on relatively wet soils, indicating similarities in humidity.From theCambridge English Corpus
The survival of eggs exposed to natural enemies was examined to see if predation could explain the low abundance of leaf beetles on farmland willows.From theCambridge English Corpus
In that scenario, the de facto default becomes folk music, where we endlessly 'strip thewillow' in a world the economy never reaches.From theCambridge English Corpus
