  • Notes on distribution, host associations, and bionomics of Erythmelus
           klopomor Triapitsyn (Hymenoptera, Mymaridae), an egg parasitoid of lace
           bugs in Missouri, USA, with particular reference to its primary host
           Corythucha arcuata (Say)(Hemiptera, Tingida)

    • Authors: B. Puttler, W. C. Bailey, S. Triapitsyn
      Abstract: The fairyfly Erythmelus klopomor Triapitsyn (Hymenoptera, Mymaridae) is an idiobiont, multivoltine egg parasitoid of lace bugs (Hemiptera, Tingidae). The parasitoid apparently reproduces thelytokously and at present is only known in the USA from 36 counties in Missouri, two in Illinois, four in Florida and one each in North Carolina and Maryland. At least a somewhat wider occurrence of the parasitoid is indicated because of the ease by which it has been reared from its primary host the oak lace bug, Corythucha arcuata (Say). It also has been reared in Missouri from the additional hosts C. cydoniae (Fitch), C. marmorata (Uhler), C. pergandei Heidemann, C. ciliata (Say), and also from Gargaphia solani Heidemann (a new host record). The parasitoid is short lived with an average life cycle of 14.5 days and apparently overwinters as an adult. Erythmelus klopomor should be considered as a candidate classical biological control agent against the recently introduced C. arcuata in Bulgaria, northern Italy, Switzerland, and Turkey, and also possibly against the well-established invasive C. ciliata in Europe.

  • Description of a new gall-inducing species of Aprostocetus (Hymenoptera:
           Eulophidae) on Melilotus indicus from Southern Italy

    • Authors: G. Viggiani, R. Monaco
      Abstract: Aprostocetus monacoi Viggiani (Hymenoptera: Eulophidae, Tetrastichinae) is described from stem galls in Melilotus indicus (Fabaceae) from Italy. It is the second native European species of Tetrastichinae known as gall inducer.

  • First record and establishment of Tuberocephalus (Trichosiphoniella)
           tianmushanensis Zang, (Hemiptera Aphididae) on ornamental cherry trees in
           Italy

    • Authors: G. Pellizzari, G. Frigimelica
      Abstract: The occurrence of the Asiatic aphid Tuberocephalus (Trichosiphoniella) tianmushanensis Zang, (=Tuberocephalus (Trichosiphoniella) higansakurae hainnevilleae Remaudière and Sorin) (Hemiptera Aphididae) in Italy is reported. The species was first detected inside leaf galls of Prunus subhirtella cv. pendula trees growing outdoors at the University Botanical Garden of Padua (Italy). Further investigations demonstrated that the species is present in plant nurseries in the Veneto region. So far this species was considered eradicated in Europe, after its first incursion in France in 1993.

  • Susceptibility of geographically isolated populations of the Tomato red
           spider mite (Tetranychus evansi Baker & Pritchard) to commonly used
           acaricides on tomato crops in Kenya

    • Authors: F. J. Toroitich, M. Knapp, J. H. Nderitu, F. M. Olubayo, M. Obonyo
      Abstract: Farmers in Kenya continue to raise concerns of difficulty in managing Tetranychus evansi, the most widespread pest species of tomato applying the most commonly used acaricides. This invasive pest species is not only found in Kenya, but in Eastern and Southern Africa, as well as parts of Europe and Asia. In the current study, populations of T. evansi were collected from farms in the four major tomato-growing areas of Kenya (Loitoktok, Kibwezi, Athi-River and Subukia) and their susceptibility compared to a laboratory culture (ICIPE) that had been maintained for three years without exposure to acaricides. Susceptibility of T. evansi eggs and adults (contact and residual) to Brigade (bifenthrin), Dimethoate (dimethoate), Karate (lambdacyhalothrin), Kelthane (dicofol), Omite (propargite) and Polytrin (profenofos+ cypermethrin) was tested in the laboratory using respective manufacturer’s recommended concentrations. Dimethoate resulted in variable ovicidal mortality while Kelthane, Brigade, Karate, Omite and Polytrin had high mortality across all populations. Similarly, adult contact and residual mortality was lower than that of the other chemicals when exposed to Dimethoate regardless of the location. Furthermore, it also had no residual effect on the mites from ICIPE and Kibwezi. On the other hand, Kelthane was most lethal against the mites from all locations followed by Brigade and Polytrin in that order. Omite caused significantly lower mortality on mites from Subukia while Karate produced variable effects on mites from Kibwezi, Loitoktok and Subukia. The implications of these findings are further discussed.
