Abstract Tuta absoluta and Bemisia tabaci are two key worldwide tomato pests. In response to chemical control limits, the use of zoophytophagous mirid predators as biocontrol agents is being increasingly studied proposed for management these However, some species in particular Nesidiocoris tenuis , which naturally occurs European crops controversial due its ability inflict significant damage on...

Our objective was to ascertain the population status of the Pygmy Three-toed Sloth, Bradypus pygmaeus, an IUCN Critically Endangered species, on Isla Escudo de Veraguas, Panama. Bradypus pygmaeus are thought to be folivorous mangrove specialists; therefore we conducted a visual systematic survey of all 10 mangrove thickets on the island. The total mangrove habitat area was measured to be 1.67 h...

Tuta absoluta (Meyrick, 1917) (Lepidoptera: Gelechiidae) is a major pest of tomato (Solanum lycopersicum L.) crops produced in the Azorean greenhouses. Despite concerns, no systematic study available to describe population dynamics T. and its natural enemies. The objective this was compare abundance (eggs larvae) native enemies, greenhouses under different production modes (biological, traditio...

Can specialist natural enemies persist in ecosystems when competing with omnivorous natural enemies for their shared prey? The consequences of omnivory have been studied theoretically, but empirical studies are still lacking. Omnivory is nevertheless common in nature and omnivorous predators coexist with specialists in many ecosystems, even when they are intraguild predators. This type of assoc...

Abstract Generalist predators are increasingly used in biological pest control for greenhouse crops, as they multiple pests and persist crops even when prey is scarce. However, some of these may cause plant damage due to their omnivorous feeding behaviour. In many European regions, the predator Nesidiocoris tenuis (Reuter) (Hemiptera: Miridae) considered be a serious tomato pest, regardless ser...
