Biology and Behaviour of Cirrospilus diallus and Cirrospilus pictus, Parasitoids of Phyllocnistis citrella

2005

International audience; Studies were carried out on some biological and behavioral aspects of Cirrospilus diallus Walker and Cirrospilus pictus (Nees) (Hymenoptera: Eulophidae) in relation to their host, the citrus leafminer (CLM), Phyllocnistis citrella Stainton (Lepidoptera: Gracillariidae). Adults of both species fed with sugar lived on average 4.45 +/- 0.19 days, whereas adults provided with honey survived on average 40.62 +/- 1.97 days. Rates of host mortality due to parasitoid stings without oviposition were as high as 31.25 and 37.73% for C. pictus and C. diallus, respectively. Both species showed arrhenotokous parthenogenesis. Sex ratios of parasitoids emerging from the 2nd and 3rd …

NECREMNUS ARTYNES (WALKER) PARASSITOIDE DI TUTA ABSOLUTA (MEYRICK) SU POMODORO, MELANZANA E SOLANUM NIGRUM L. IN SERRA A CONDUZIONE BIOLOGICA

2011

Nel 2010, in serre del palermitano gestite secondo i canoni dell'agricoltura biologica, è stato condotto uno studio volto all'individuazione degli antagonisti naturali indigeni del lepidottero gelechide Tuta absoluta, fitofago esotico dannoso alle solanacee recentemente introdotto in Italia. Le piante campionate sono state il pomodoro, da gennaio a giugno, la melanzana, da fine marzo a giugno, e Solanum nigrum che cresceva spontaneamente all'interno delle serre in piccoli spazi liberi dalle solanacee coltivate. Per tenere sotto controllo il gelechide, il serricoltore ha effettuato tre trattamenti con Bacillus thuringiensis da metà marzo a fine aprile. Oltre al predatore Nesidiocoris tenuis,…

Behavioral responses of the parasitoid Melittobia digitata to volatiles emitted by its natural and laboratory hosts

2010

Responses of macropterous females of the ectoparasitoid Melittobia digitata Dahms (Hymenoptera: Eulophidae) to direct and indirect cues emitted by its natural hosts as well as laboratory hosts were investigated using a Y-tube olfactometer. To locate the nest ofmud dauber wasps, Trypoxylon politum Say (Hymenoptera: Crabronidae), and one of their inquilines, Anthrax spec., parasitoids exploit volatiles from the freshly built nest mud and the empty cocoon constructed by the wasps, as well as their meconium. However, the parasitoids did not respond to odors emitted by older nest mud or by the host stages that are attacked (T. politum prepupae and Anthrax spec. larvae). Melittobia digitata was n…
