ABSTRACT
In this study, a new species of mealybug from the Cape Verde Islands, Mirococcus capeverdensis Lagowska and Hodgson sp. n., collected on Campylanthus glaber Benth. (Scrophulariaceae), a native plant to these islands, is described and illustrated based on the adult female. A taxonomic key to the mealybugs from the Afrotropical Region that lack cerarii is provided. In addition, seven scale insect species, namely Aulacaspis tubercularis Newstead, Hemiberlesia cyanophylli (Signoret), Pseudaonidia trilobitiformis (Green), Icerya aegyptiaca (Douglas), Maconellicoccus hirsutus (Green), Palmicultor palmarum (Ehrhorn), and Pseudococcus comstocki (Kuwana) are recorded for the first time from the Cape Verde Islands and an updated checklist of Coccomorpha species known from this region, along with their known island distributions and valid sources, is appended.
ABSTRACT
A checklist of scale insects recorded to date in Poland is presented. The data provided here are based on literature records and include the latest taxonomic and nomenclatural changes and updates on Coccomorpha reported in Poland. Changes in comparison with ScaleNet and Fauna Europaea electronic databases are also discussed. A total of 185 species belonging to 98 genera and 16 families are included in the list. Of this group, 47 species are alien introduced species and live only indoors, and one species, Pulvinaria floccifera (Westwood), develops both indoors and outdoors.
ABSTRACT
A new species of soft scale (Hemiptera: Coccomorpha; Cocccidae) from South Africa, Coccus giliomeei Lagowska Hodgson sp. n., collected on Gymnosporia buxifolia (L.) Szyszyl, is described and illustrated. Also, Coccus rhodesiensis (Hall) is recorded for the first time from South Africa and is redescribed and illustrated based on the adult females of the type series and fresh South African specimens. An updated key to the species of Coccus and similar species known from Africa is included. Based on this latter study, (i) Marsipococcus proteae (Brain) and M. durbanensis (Brain) are considered not to be congeneric with Marsipococcus marsupialis (Green), the type species of Marsipococcus Cockerell Bueker, and are placed in a new genus Proteacoccus Lagowska Hodgson, gen. n. with Lecanium proteae Brain as the type species; (ii) it is considered that Coccus asiaticus Lindinger is clearly not a junior synonym of Parasaissetia nigra (Nietner) and is accepted as a full species, rev. stat., and (iii) Neoplatylecanium adersi (Newstead) is considered to be non-conspecific with N. cinnamomi Takahashi, the type species of Neoplatylecanium Takahashi, and is transferred to Maacoccus Tao Wong, as Maacoccus adersi (Newstead), comb. n.

Due to an oversight, the depositories of the new species, Coccus giliomeei Lagowska Hodgson, and of the new material of Coccus rhodesiensis (Hall) collected in the Transvaal, South Africa, was omitted from the manuscript. Both lots of slides will be deposited in SANC, The South African National Collection of Insects, Pretoria, South Africa.

The induction of plant resistance against pests is considered a potential method of controlling mite infestation as it restricts the use of chemical pesticides in herbal crops. Our goal was to investigate whether plant physiological response to mite feeding varied depending on basil cultivar and/or duration of mite infestation. The effect of plant acceptance, mite mortality rate, and changes in physiological parameters: malondialdehyde content (MDA), hydrogen peroxide (H2O2) concentration, and antioxidant enzyme activities, including guaiacol peroxidase (GPX) and catalase (CAT) were examined in this study. Tetranychus urticae Koch (Acari: Tetranychidae) infestation induced oxidative stress in three Ocimum basilicum L. cultivars: 'Sweet basil,' 'Purpurascens,' and 'Fino Verde.' The analysis of mite behavior and alteration in metabolic plant profiles showed different sensitivities of basil cultivars to biotic stress that were dependent on the cultivar and duration of infestation. All basil plants were suitable as host plants for T. urticae, but they varied in the level of susceptibility to mite feeding. O. basilicum 'Fino Verde' was the most suitable host for the twospotted spider mite. In turn, O. basilicum 'Purpurascens' was characterized by the lowest level of susceptibility to T. urticae feeding. The lowest acceptance, the highest mortality of twospotted spider mite individuals as well as decreased levels of H2O2 and MDA, significantly increased GPX activity and low level of CAT activity were recorded in O. basilicum 'Purpurascens' leaves. Research on plant responses to biotic stress can inform breeding cultivars resistant to arthropod attack.

The adult female, first-instar nymph, second-instar male, third-instar female, pupa and adult male of a new species of Marsipococcus Cockerell & Bueker (Hemiptera: Coccomorpha: Coccidae) from Malaysia, M. ulubendulensis Lagowska & Martin sp. n., are described and illustrated, while the second-instar female is only described. Marsipococcus is rediagnosed and a key to the adult females of the four species now placed in this genus is included.

All life stages (adult female and male, first-instar nymph, second-instar male and female nymphs, and prepupa and pupa) of a new species of Asterolecaniidae, Bambusaspis transversa Lagowska & Martin sp. n., from bamboo in Malaysia, are described and illustrated. The adult female and first-instar nymphs are compared with those Bambusaspis species considered to be closest to the new species.
