A study of the mealybug genus Planococcus Ferris, 1950 (Hemiptera, Coccomorpha, Pseudococcidae) known from China is presented and 12 species are recognised. Of these, camelliae Zhang, sp. nov. described as new to science based on morphology adult female, P. bambusifolii (Takahashi, 1951) recorded for first time. Molecular analyses mitochondrial gene cytochrome c oxidase subunit I (COI) a key in...

Flavobacteria and Enterobacteriaceae have been previously reported as scale insect endosymbionts. The purpose of this work was twofold: first, to screen different scale insect families for the presence of these endosymbionts by PCR analyses and second, to elucidate the history of cophylogeny between these bacteria and the insects by analysing a portion of 16S rRNA and 18S rRNA gene sequences by...

Medicinal and aromatic plants are used primarily in the medicine, food cosmetic industries. Scale insect species belonging to Coccomorpha (Hemiptera: Sternorryncha) feed on medicinal plants, reducing yield commercial value of these crops. This study aimed determine scale Adana Province between 2015 2017. samples were collected from leaves, trunks, brunches fruits 28 plant examined identified la...

New cytogenetic data are reported for 17 species from 15 genera of the families Pseudococcidae, Eriococcidae, Kermesidae, and Coccidae. Twelve species and 6 genera (Peliococcopsis Borchsenius, 1948, Heterococcopsis Borchsenius, 1948, Heliococcus Šulc, 1912, Trabutina Marchal, 1904, Lecanopsis Targioni Tozzetti, 1868, and Anapulvinaria Borchsenius, 1952) were studied cytogenetically for the firs...

The genus Trionymus (Berg, 1899) (Hemiptera: Coccomorpha: Pseudococcidae) was investigated based on samples collected plants from Poaceae, Cyperaceae and Juncaceae in Aydın Province, Turkey, between 2019 2020. specimens of the new species were Juncus acutus L. (Poales: Juncaceae) slide-mounted. In total, 10 examined under a microscope illustrations prepared. As result study, oncueri sp. n. Kayd...

A survey was carried out at Bandirippuwa Estate, Kir imetiyana Estate and at Isolated Seed Garden, Rajakadaluwa for the pests of coconut inflorescence and developing fruits. The mite, Dolichotetranychus sp. (Tenuipalpidae) which lives beneath the perianth and feeds on the epicarp, causes considerable damage to the developing fruit. Bi-monthly observations on the intensity of infestation of nuts...

The toxicity of 2 reduced-risk pesticides, 2% horticultural oil with 0.05% Silwet L-77 and Grandevo (Chromobacterium subtsugae Strain PRAA4-1T), to 2 predators: Metaseiulus occidentalis (Nesbitt) (Acari: Phytoseiidae) and Hemicheyletia wellsina DeLeon (Acari: Cheyletidae), and 3 orchid pests: the two-spotted spider mite Tetranychus urticae Koch (Prostigmata: Tetranychidae), the phalaenopsis mit...

A list of scale insects (Hemiptera: Sternorrhyncha: Coccoidea) of Iran is present based mainly on the literature records since 1902. In total, 13 families and 275 species have been recorded and these are listed along with their locality data and host plants. The families are as follows: Asterolecaniidae, Cerococcidae, Coccidae, Diaspididae, Eriococcidae, Kermesidae, Margarodidae, Monophlebidae,...

A new species of the genus Acerophagus Smith (Hymenoptera: Encyrtidae), A. belenaguirreae sp. n., is described from Vieques Island, Puerto Rico (USA) as a primary parasitoid mealybug Hypogeococcus (Hemiptera: Pseudococcidae) on Achyranthesaspera var. aspera (Amaranthaceae) and Portulaca (Portulacaceae). An identification key to females in New World with dark cross bands gastral dorsum provided....
