Nematodes and insects are the two dominant animal taxa in species numbers, and nematode-insect interactions constitute a significant portion of interspecies associations in a diversity of ecosystems. It has been speculated that most insects represent mobile microhabitats in which nematodes can obtain food, mobility, and shelter. Nematode-insect associations can be classified as phoretic (insect...
Choice tests are a standard method to determine preferences in bio-assays, e.g. for food types and food additives such as bait attractants and toxicants. Choice between food additives can be determined only when the food substrate is sufficiently homogeneous. This is difficult to achieve for wood eating organisms as wood is a highly variable biological material, even within a tree species due t...
The response of female tabanids to natural attractants was studied in the Monjoros Forest along the Nature Park Kopacki rit in eastern Croatia. Tabanids were caught in canopy traps baited with either aged cow, horse, sheep, or pig urine and also in unbaited traps. Tabanids were collected in a significantly higher numbers in traps baited with natural attractants compared to unbaited traps. The n...
We evaluated five herbivore-induced plant volatiles plus a male-produced pheromone as attractants for adult green lacewings in Washington apple orchards in 2008. We found at least five attractants or combinations of attractants were attractive to the three most abundant green lacewing species in our trials. Chrysopa nigricornis and Chrysopa oculata were attracted to the combination of methyl sa...
The use of semiochemicals, both sex pheromones and food attractants, in monitoring the olive fly, Bactrocera oleae, has become well established in most olive-growing countries of the Mediterranean basin. There is an ever-increasing degree of sophistication that is being introduced in the way trap catch data are collected and interpreted, making for a substantially more rational use of conventio...
In this paper, the biosynthesis process of phenolic compounds in plants is summarized, which include the shikimate, pentose phosphate and phenylpropanoid pathways. Plant phenolic compounds can act as antioxidants, structural polymers (lignin), attractants (flavonoids and carotenoids), UV screens (flavonoids), signal compounds (salicylic acid, flavonoids) and defense response chemicals (tannins,...
