Emergence, dispersal, and mate finding via a substrate-borne sex pheromone in the parasitoidMetaphycus luteolus

2013

Metaphycus luteolus Timberlake (Hymenoptera: Encyrtidae) is a facultatively gregarious parasitoid of soft scale insects. We conducted behavioral experiments to better understand the mating structure of this species. Emergence of male and female offspring is synchronized, beginning at the onset of photoperiod. Both sexes are able to disperse, although dispersal of males from natal patches appears to take longer than dispersal of females. We demonstrated the presence of a female-produced contact pheromone using open arena bioassays and motion tracking software, testing residues deposited by walking females, and extracts of females. Males responded to the females' chemical footprints' and to a…

New Mediterranean records of Trabutina mannipara (Hemprich & Ehrenberg 1829) (Hemiptera: Coccomorpha: Pseudococcidae)

2018

The occurrence of Trabutina mannipara (Hemprich & Ehrenberg, 1829) (Hemiptera: Coccomorpha) is reported for the first time at Linosa (Pelagian Islands, Sicily Channel, Italy) and Libya. T. mannipara was approved by USA authorities for release as biocontrol agents against invasive saltcedars. The potential impact of this species, that in the Mediterranean area showed to be occasionally invasive, is discussed.

First record of Icerya seychellarum and confirmed occurrence of Aulacaspis tubercularis (Hemiptera: Coccomorpha) in Italy

2020

The Seychelles scale, Icerya seychellarum (Westwood, 1855) (Hemiptera: Coccomorpha: Monophlebidae), is reported for the first time in Italy. Moreover, the occurrence of the white mango scale, Aulacaspis tubercularis (Newstead, 1906) (Hemiptera: Coccomorpha: Diaspididae), firstly reported in 1990 on mango trees growing outdoors in a nursery near Milazzo (Messina province, Sicily), and then intercepted in 2013 on mango plants imported from Florida (USA) to the Botanical Garden in Padova (Italy), is confirmed. Both species were found in two Sicilian mango orchards located in the province of Messina. Their introduction is most likely due to the orchards planting using infested mango nursery pla…
