Invasive insect species enter new environment mainly with their host plants and spread rapidly in new conditions due to the absence of natural entomophages that can effectively limit their numbers. Comprehensive studies of the invaders, including crop pest, are of great importance for agricultural practice. In this regard, we investigated mealybugs (Pseudococcidae) in the orchards of five subtropical species, viz. lemon (Citrus limon) mandarin (Citrus reticulate), orange (Citrus sinensis), persimmon (Diospyros kaki), and pomegranate (Punica granatum) in the Lankaran-Astara Region of Azerbaijan. The research was conducted in 2016‒2019 in various seasons. Three mealybug species were recorded from the area in question: Pseudococcus comstocki Kuwana 1902, Pseudococcus viburni Signoret 1875, Pseudococcus calceolariae (Maskell, 1879). An annotated list of species provides collecting localities, their geographical coordinates, dates of collection, and the number of individuals found. We obtained data on species distribution, biology, host plants and signs of infestation. Ps. viburni was registered in the fauna of Azerbaijan for the first time; a developement period of its larvae and imagoes is provided. The highest infestation of the vegetative organs was observed on the citrus plants: on average, 30 % of trees were damaged by Ps. comstocki, 27 % by Ps. viburni, and 21 % by Ps. calceolariae. Two mealybug species (Ps. comstocki, Ps. viburni) were found on the persimmon and only one species (Ps. comstocki) on the pomegranate. Ps. comstocki population density was the highest in the study area (3–5 larvae per 10 cm of branches, and 4–5 colonies per 100 leaves during flowering). All three species were found together on the stems and leaves of citrus crops; Ps. comstocki was observed on the fruits of mandarin and persimmon, and Ps. viburni was only on the persimmon. Based on the data obtained, the degree of harmfulness of the above species was determined: for Ps. comstocki – 3–5 larvae per 10 cm of branches, and 4–5 colonies per 100 leaves during flowering; for Ps. viburni – 2–3 larvae per 10 cm of branches, and 3–4 colonies per 100 leaves during flowering; and for Ps. calceolariae – 2–3 larvae per 10 cm of branches, and 2–3 colonies per 100 leaves during flowering.

Tamarixia schina Zuparko sp. nov. and T. dahlsteni Zuparko sp. nov. are described. Both species have become established in California following their introductions from Chile and Australia, respectively, for control of invasive psyllids. Tamarixia schina is known from Calophya schini (Hemiptera: Calophyidae) on Schinus molle (Anacardiaceae) and T. dahlsteni from Trioza eugeniae (Hemiptera: Triozidae) on Syzygium paniculatum (Myrtaceae). The use of Tamarixia in biological control is discussed, and an annotated list of world species including distribution, hosts, and host plants, is provided. Tetrastichus atamiensis Ashmead is transferred to Tamarixia as Tamarixia atamiensis (Ashmead) comb. n.

An understanding of the complex ecological interaction between fig wasps and their host plants in Amazonia requires previous knowledge of their distribution and diversity. The objective of this study was to describe the composition and structure of the wasp community associated with four species of Ficus in the municipal area of Manaus, Amazonas, Brazil. A total of 600 syconia from four species were collected. The study species were: Ficus obtusifolia Kunth; Ficus citrifolia Mill; F. americana subspecies guianensis Desv. form mathewsii; and F. americana subspecies guianensis Desv. form parkeriana. Statistical analyses were used to examine the relationship between fig wasp diversity and syconium diameter, and the effect of non-pollinating wasps on numbers of pollinators and seeds. Forty three species of fig wasp were identified, distributed across seven genera (Pegoscapus, Idarnes, Aepocerus, Physothorax, Anidarnes, Heterandrium , Eurytoma). Idarnes (carme group) was the wasps genus non-pollinator with greatest number of individuals with the greatest number of infested syconia (7409 wasps in 376 syconia). Analysing non-pollinating wasp diversity in relation to fig diameter, a significant difference was observed between the four fig species. Ficus citrifolia and F. americana subspecies guianensis form mathewsii had the smallest diameter but the greatest diversity of fig wasp. Ficus obtusifolia was the only species in which the non-pollinating wasps had a significant negative effect on the number of Pegoscapus sp. and on seed production.

Study Species

Mealybugs (Coccoidea: Pseudococcidae) are serious pests, particularly as invasive species on many agricultural products. Morphological identification of mealybugs is based on adult female characters that, in the absence of adult females or with damaged specimens, can be problematic, especially when identification is required urgently, such as that involving the exportation/importation market. In this study, species-specific primers were designed to identify three of the most abundant mealybug species found on ornamental plants in Guilan province, Iran: Planococcus citri (Risso), Pseudococcus viburni (Signoret) and Pseudococcus comstocki (Kuwana). By generating amplification products of different sizes, the three species-specific primers, along with universal COI primers, were successfully used in multiplex PCR tests to identify all three mealybug species in a single reaction. Analysis of a large array of specimens from different geographic locations on different host plants showed that this was a reliable and accurate method.
