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.

The hypopi of the species Sancassania chelone Oudemans, 1916 were collected from four pest beetle species, namely Melolontha melolontha (Linnaeus, 1758); Melolontha hippocastani Fabricius, 1801; Holochelus aequinoctialis (Herbst, 1790) and Tropinota hirta Poda, 1761. The infestation rate was the highest in H. aequinoctialis (80%), while it was 50%, 28% and 13% in M. hippocastani, M. melolontha and T. hirta, respectively. The majority of the mites were found on wings in case of the two Melolontha species, in contrary, the mites were present on the abdomen of the H. aequinoctialis and T. hirta. Melolontha hippocastani Fabricius, 1801; Holochelus aequinoctialis (Herbst, 1790) and Tropinota hirta (Poda, 1761) are new host species of S. chelone.

The present study was carried out to identify parasitoids of bark beetles in the forests of northern Iran, from 2013–2015 (May–August). Four hymenopterans species belonging to 3 families (Eulophidae, Pteromalidae and Braconidae) were identified as Ecphylus silesiacus (Ratzeburg, 1848), Cheiropachus quadrum (Fabricius, 1787), Rhaphitelus maculatus Walker, 1834 and Entedon ergias (Ratzeburg, 1844). Among the identified bark beetles species, T. lenkoranus Reitter, 1913 was recorded as a new host of E. silesiacus for the first time in the world.
Recently, the senior author discovered the presence of a whitefly on sugarcane,
, in Qena, Egypt, and sent specimens to the junior author who identified it as
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.
Three specimens of invasive pest mite, Brevipalpus californicus (Banks, 1904) were collected on leaves of Dracaena marginata ʻTricolorʼ plant. The collected specimens belong to the Beard et al. (2015) “species B group” on the basis of the morphology of prodorsal and opisthonothal pattern. A new key to the Hungarian Brevipalpus is given.

This paper reports the detection of the myxozoan species Myxobolus elegans Kashkovsky 1966 in common dace (Leuciscus leuciscus) that has not been previously listed as its host. The problem of differentiation of phenotypically similar Myxobolus species is addressed. During parasitological survey of common dace from the desalinated part of the Gulf of Finland at the city of Sestroretsk, Russia, numerous oval-shaped plasmodia, 0.2–0.4 mm in size, filled with Myxobolus spores were found on the gills. Pear-shaped myxospores were 15.4 (14.8–16.0) × 10.2 (9.6–10.9) µm in size with a rib on each valve. On the basis of spore morphology, the species appeared to be similar to M. elegans and Myxobolus hungaricus Jaczó, 1940. In order to identify the species, molecular genetic analysis was performed, and the species was identified on the basis of morphological characteristics and 18S rDNA data. The results obtained indicate that the Myxobolus species observed on the gills of dace is M. elegans. Thus, common dace is another valid host of M. elegans besides the type host, ide (Leuciscus idus).

Aceria bambusae ChannaBasavanna, 1966 is reported from Hungary for the first time. The species was collected from the leaf sheaths of the introduced bamboo species, Phyllostachys rubromarginata McClure and Phyllostachys tianmuensis Z.P. Wang et N.X. Ma (both Poaceae) in Hungary. Morphological differences distinguishing this species from other bambusoid inhabiting congeners are discussed. In addition, new date-locality-host records for 3 eriophyoid species collected from 7 bamboo species are given.
Authors give a report on four eriophyoid species which were new for the Hungarian fauna (Aculops berochensis Keifer and Delley; Aculops parakarensis Bagdasarian; Aculus ligustri Keifer; Aculus? crataegumplicans Cotte). Three of them were found on new host-plants.
Aculodes dubius (Nalepa), Aculodes mckenziei (Keifer) and Aceria tosichella Keifer were recorded for the first time in Hungary. Festuca pratensis, Phleum phleoides and Bromus inermis were found as new host-plants of Aculodes dubius, althought other plant species in these generas are known to be hosts of this mite. Aceria tulipae (Keifer) was indentified on Phleum pratense and Aceria tenuis (Nalepa) on Phleum phleoides, which were also new host-plants for them.
