Effect of plant nitrogen and water status on the foraging behavior and fitness of an omnivorous arthropod
Omnivorous arthropods make dietary choices according to the environment in which they forage, mainly availability/quality of plant and/or prey resources. Such decisions and their subsequent impacts on life-history traits may be affected by the availability of nutrients and water to plants, that is, through bottom-up forces. By setting up arenas for feeding behavior observation as well as glassh...
متن کاملLethal and behavioral effects of pesticides on the insect predator Macrolophus pygmaeus.
Macrolophus pygmaeus (Hemiptera: Miridae) is a common generalist predator in Mediterranean agro-ecosystems. We evaluated the lethal effects of six insecticides and a fungicide on M. pygmaeus nymphs exposed to the pesticides through three routes of exposure: direct, residual and oral. Chlorantraniliprole and emamectin-benzoate caused less than 25% mortality to M. pygmaeus and were classified as ...
متن کاملEffect of hunger level on prey consumption and functional response of the predator Macrolophus pygmaeus
A study was conducted to examine the influence of the hunger level on the prey consumption of Macrolophus pygmaeus Rambur (Hemiptera Miridae) at varying densities of Myzus persicae Sulzer (Hemiptera Aphididae) through laboratory functional response experiments. Newly emerged adult females of the predator were subjected to 24 or 48 h of prey deprivation on pepper plant, as well as to 48 h only o...
متن کاملLife-History Traits of Macrolophus pygmaeus with Different Prey Foods
Macrolophus pygmaeus Rambur (Hemiptera: Miridae) is a generalist predatory mirid widely used in augmentative biological control of various insect pests in greenhouse tomato production in Europe, including the invasive tomato leafminer, Tuta absoluta (Meyrick) (Lepidoptera, Gelechiidae). However, its biocontrol efficacy often relies on the presence of alternative prey. The present study aimed at...
متن کاملComparative cytogenetic study of three Macrolophus species (Heteroptera, Miridae)
Macrolophus pygmaeus (Rambur, 1839) (Insecta, Heteroptera, Miridae) is a predator of key vegetable crop pests applied as a biocontrol agent in the Mediterranean region. Macrolophus pygmaeus and Macrolophus melanotoma (A. Costa, 1853) are cryptic species with great morphological similarity which results in their misidentification and negative consequences for the conservation of their population...
