Recently, the senior author discovered the presence of a whitefly on sugarcane, Saccharum officinalis , in Qena, Egypt, and sent specimens to the junior author who identified it as Bemisia formosana Takahashi (Homoptera: Alyerodidae). Since this is the first report of this species occurring on sugarcane, an economic crop, and the first distribution record of it occurring in Egypt and the Mediterranean region, we thought it expedient to publicize the information to alert workers in the region to its presence.

Species of the family Signiphoridae (Chalcidoidea) are primarily hyperparasitoids associated with scale insects, whiteflies and mealybugs through other Chalcidoidea; however, certain species are primary parasitoids of these hosts. Recent collections and a review of the literature indicate that the following five species of the family Signiphoridae are known to occur in Egypt: Chartocerus niger (Ashmead), Chartocerus subaeneus (Főrster), Signiphora fax Girault, Thysanus sp. and Signiphora flavella Girault, the latter newly recorded in Egypt and Palearctic region. A key to the Egyptian signiphorid species is included.

Blepyrus insularis (Cameron) (Encyrtidae) was reared from Phenacoccus parvus Morrison, an invasive mealybug recently found infesting Psidium sp. in Egypt. Encarsia cibcensis Lopez-Avila (Aphelinidae) was reared from Aleuroclava psidii (Singh) (Hemiptera: Aleyrodidae), an invasive whitefly found on Ficus sp. in Egypt. Mesopeltita truncatipennis (Waterston) (Pteromalidae) was reared from the lecanodiaspid scale, Lecanodiaspis africana (Newstead) (Hemiptera: Lecanodiaspididae) on Ficus sp. All of these represent new host records for the parasitoids.
