Ophelimus maskelli (Ashmead) (Hymenoptera: Eulophidae), an invasive species in the Mediterranean area that occurs naturally onEucalyptus camaldulensis at Wagga Wagga in New South Wales, was studied in Israel on the same host plant. The most distinctive characteristic of O. maskelli as compared with other congeners is the presence of only a single seta on the submarginal vein. O. maskelli shows a clear tendency to oviposit in developed, immature leaves, and it prefers to oviposit on an area of the leaf blade near the petiole. The female lays an average of 109 eggs when maintained on water alone. The egglaying distribution tended towards aggregation, and the same tendency has also been observed within and among trees. The wasp prefers to attack the lower canopy. The gall diameter ranged from 1.2 to 0.9 mm, and gall density from 11.5 to 36.0 galls cm−2, respectively. The typical color of the gall appeared as soon as third instar larva developed. Galls on shaded leaves remained green or greenish-yellow, whereas those that were exposed to the sun were reddish. O. maskelli produces three generations per year in Israel. High flight occurs among the spring generations, starting in early March. The wasps were attracted to green sticky plates much more than to the other tested colors. Heavy galling by O. maskelli results in premature shedding of the leaves, soon after the emergence of the wasps. Among the 84 eucalyptus species tested, the following 14 species were found to be suitable hosts:E. botryoides, E. bridgesiana, E. camaldulensis, E. cinerea, E. globulus, E. gunii, E. nicholii, E. pulverulenta, E. robusta, E. rudis, E. saligna, E. tereticornis and E. viminalis. This study focused on morphological and development characters that can clearly distinguish O. maskelli from Ophelimus eucalypti Gahan, and on examining the effect of crossing between eucalyptus species on the development possibilities of the wasps. Also considered were the effect of the food on adult survival, the competition between the eulophid gall makerLeptocybe invasa Fisher & LaSalle and O. maskelli, the heavy damage inflicted on eucalyptus, and the health problems and nuisance to people caused by the wasp near heavily infested trees during the mass emergence of adults.

Leptocybe invasa Fisher & LaSalle, a new genus and species of Eulophidae, displays thelytokous reproduction, forming typical bump‐shaped galls on the leaf midribs, petioles and stems of new growth of several Eucalyptus species. Presently, this wasp occurs in large areas in the Middle East, the Mediterranean and Africa, and is a serious pest in young plantations. Heavy galling prevents further development of the infested growth. Leptocybe invasa is only known from females. Mean length of a gall containing a single wasp is 2.1 mm, leaves of intensively growing trees may carry over 50 galls per leaf. Mean development time from oviposition to emergence is 132.6 d in room temperature. In Israel the wasp produces two or three overlapping generations annually. Mean survival time for wasps fed with honey and water is 6.5 days. Ten species were found to be suitable hosts in Israel: E. botryoides, E. bridgesiana E. camaldulensis, E. globulus. E. gunii. E. grandis, E. robusta, E. saligna, E. tereticornis, and E. viminalis.

The Australian bug species Thaumastocoris peregrinus Carpineto et Dellapè (Hemiptera: Thaumastocoridae) is reported for the first time in Greece. This is a sap-sucking consumer (mesophyll feeder) of Eucalyptus spp. foliage. Feeding damage and the egg batches of the insect were found in several locations in 2016. This invasive species recently has been recorded from Portugal, Spain, and Italy. Although in Greece there are no currently forest plantations of eucalypts (experimental plantations exempted), this insect is a serious pest of these trees in roadside verges and city parks.

We present the first Middle-Eastern record of Thaumastocoris peregrinus Car­pintero & Dellapé, an invasive pest that feeds and develops only on euca­lyp­tus trees. This species was found in Israel for the first time in Eucalyptus camaldu­lensis stands in October 2014. A survey of several eucalyptus groves was con­ducted in Tel Aviv and its surroundings to assess the geographical dis­tri­bu­tion and host-plant associations of T. peregrinus. We summarize new and old data on this species, i.e., its identification, immature stages, bio­logy, pheno­logy, and damage caused to the host plant.

The Eucalyptus pest Thaumastocoris peregrinus Carpintero et Dellape, (Hemiptera Thaumastocoridae) was found in a Eucalyptus arboretum in Lisbon, Portugal, in April 2012. This is the first report for this species in Western Europe. Separate surveys were conducted to assess the geographical distribution, host plant susceptibility and natural enemies of T. peregrinus. To ascertain the geographical distribution of T. peregrinus surveys were conducted between May and June 2012 at 53 sites in central and southern Portugal. T. peregrinus was present in only three sites, which were all located in Lisbon and surrounding areas suggesting an introduction pathway through the harbors or the airport in this coastal city. Of the 30 Eucalyptus species present in Lisbon’s Eucalyptus arboretum, 14 were confirmed as infested by T. peregrinus during the first survey in April 2012. In August 2012 the host range had increased to 19 Eucalyptus species, revealing an expansion phase. We report the first record of Hemerobius bolivari Banks (Neuroptera Hemerobiidae), a native of South America, preying on T. peregrinus nymphs. This is the first record of H. bolivari in Europe and we hypothesized that this predator may have reached Europe together with its prey.
