The papaya mealybug, Paracoccus marginatus Williams & Granara de Willink (Hemiptera: Coccomorpha: Pseudococcidae) has been found in Israel for the first time. This is also the first record of this invasive species in the Western Palaearctic region. The mealybug was detected at two locations in Northern Israel and was not accompanied by its principal natural enemies. Paracoccus marginatus is highly polyphagous and may develop large populations in Israel on annona, hibiscus, mulberry, papaya and the invasive weed Parthenium hysterophorus.

Two eucalypt-feeding psyllids (Hemiptera: Psylloidea: Aphalaridae): the eucalypt shoot psyllid, Blastopsylla occidentalis Taylor and the red gum lerp psyllid, Glycaspis brimblecombei Moore are reported from Israel for the first time. Both species belong to Spondyliaspidinae, a subfamily of jumping plant lice that feed generally on Myrtaceae, mainly eucalypts. The psyllids were collected from Eucalyptus camaldulensis Dehnh., a dominant eucalypt species in Israel. A summary of the global distribution and the host trees of the two psyllids are provided and their potential threat to eucalypts in Israel is discussed. Diagnostic information to distinguish between the two psyllids is presented, with an identification key for the adults of six eucalypt-feeding psyllid species in the Western Palearctic region.
