A preliminary inventory of scale insects (Hemiptera: Coccoidea) developing on the mango tree is presented for Northern and Central Benin. The following species, Gigantococcus euphorbiae, Gigantococcus nigroareolatus, Ceroplastes uapacae, Parasaissetia nigra, Saissetia privigna, Udinia catori, Ferrisia virgata, Paracoccus interceptus, Phenacoccus solenopsis, Rastrococcus invadens, Aonidiella orientalis and Lepidosaphes tapleyi, were collected from 2005 to 2007 in mango orchards in the Sudanian area of Benin, on branches, leaves, and particularly on mango petioles and fruits. Nine of these species are recorded for the first time in Benin while P. interceptus is recorded in Africa for the first time. Only two, R. invadens and A. orientalis, of the 12 species are considered as mango pests.

Great medieval scientist-polymath Abu Rayhan Al-Beruni (973–1050) wrote in his book “Pharmacognosy” about some kind of “worms” inhabiting willows in Azerbaijan and Southern Iran and used by native people for producing of a red dye. It was unclear during one thousand years which organisms Al-Beruni noted as those dye-producing “worms”. Some modern authors even suggested that the relevant medieval text was partly erroneous. To the contrary, in the present paper we, for the first time, consider some species of the felt scale insects (Coccinea: Eriococcidae) as the organisms, which have probably been used for the production of the red dye in the medieval countries of Western and Central Asia. These insects are several species from two closely related genera Acanthococcus Signoret, 1875 and Gossyparia Signo­ret, 1875. The review of biological characters, identification key, new figures and colour photographs are provided for the species of Acanthococcus and Gossyparia associated with Salix spp. in the Asiatic Region. Acanthococcus turanicus Matesova, 1967, syn. nov. is placed in synonymy with A. salicis (Borchsenius, 1938), and A. altaicus Matesova, 1967, syn. nov. is placed in synonymy with A. spiraeae Borchsenius, 1949. Earlier discovered synonymy of A. melnikensis (Hodgson et Trencheva, 2008) with A. aceris Signoret, 1875 is discussed. Some other dye-producing scale insects and their pigments are also briefly considered.

Male Morphology

In the past, the morphology of adult males of Coccoidea has provided strong support for diagnosing the higher taxonstatus of scale insects (Coccoidea). In particular, studies on adult male morphology have produced some of the stron-gest evidence for considering the Putoidae and Eriococcidae (as then defined) as separate families from the Pseudo-coccidae. This paper uses adult male morphology to assess the relationships of the Pseudococcidae and the hypogaeicand myrmecophilous mealybugs. The latter most often are classified as a subfamily (Rhizoecinae) of the Pseudococ-cidae. In order to diagnose the latter taxa, the adult males of fifteen named species of hypogaeic rhizoecine mealybugs(Kissrhizoecus hungaricus Kozár & Konczné Benedicty, Rhizoecus cacticans (Hambleton), Rh. coffeae Laing, Rh.dianthi Green, Rh. falcifer Künckel d’Herculais, Rh. kazachstanus Matesova, Ripersiella cryphia (Williams), Ri.hibisci (Kawai & Takagi), Ri. kondonis (Kuwana), Ri. malschae (Williams), Ri. puhiensis (Hambleton), Capitisetellamigrans (Green) and Pseudorhizoecus proximus Green) plus two unidentified Ripersiella species are described. Inaddition, the adult males of a Xenococcus sp., three Eumyrmococcus spp. and two Neochavesia spp. are illustratedfrom previously published papers and the adult male of another Neochavesia sp. is described and illustrated. In orderto compare the diagnoses of the above taxa with that of adult males of Pseudococcidae (minus the Rhizoecinae), theadult males of two apterous pseudococcid mealybugs are described or redescribed: Asaphococcus agninus Cox andthe myrmecophilous Promyrmococcus dilli Williams, both belonging to the Pseudococcinae. In addition, threemacropterous Pseudococcidae, namely Phenacoccus solenopsis Tinsley (Phenacoccinae), Planococcus glaucus(Maskell) and Maconellicoccus hirsutus (Green) (Pseudococcinae) are also described and/or illustrated. Prior to thisstudy, the hypogaeic and myrmecophilous mealybugs generally were included in the subfamily Rhizoecinae of thePseudococcidae, with the hypogaeic mealybugs in tribe Rhizoecini and the myrmecophilous mealybugs in Xenococ-cini. Based on the present study and on phylogenetic data, it is concluded that the rhizoecine mealybugs form a sepa-rate family from the Pseudococcidae — Rhizoecidae Williams. This family is considered here to include twosubfamilies, Rhizoecinae Williams and Xenococcinae Tang. Based on adult male characters, there is little support forthe present generic divisions of the Rhizoecinae. Keys are given for separating the adult males of Rhizoecidae from those of Pseudococcidae, and for separating the known adult males within each subfamily.

The karyotype of Psoraleococcusmultipori (Morrison, 1921) was studied for the first time, based on material from Indonesia (Sulawesi). The diploid chromosome number was found to be 18 in both males and females, but some cells contained also additional small chromosomal elements, probably B chromosomes. About 50 % of the studied embryos demonstrated paternal genome heterochromatinization of one haploid set of chromosomes (PGH) suggesting presence of a Lecanoid genetic system. The embryos with PGH are known to be always the male embryos in scale insects and so, bisexual reproduction may be presumed for P.multipori. The information provided represents the first probative cytogenetic data for the subfamily Lecanodiaspidinae Targioni Tozzetti, 1896 as a whole. A detailed morphological figure and photos of female and male embryonic cells are given. Additionally, it was discovered that the females of P.multipori exhibit complete ovoviviparity.

AbstractScale insects (Hemiptera: Coccoidea) are key pests of agricultural crops and ornamental plants worldwide. Their populations are difficult to control, even with insecticides, due to their cryptic habits. Moreover, there is growing concern over the use of synthetic pesticides for their control, due to deleterious environmental effects and the emergence of resistant populations of target pests. In this context, biological control may be an effective and sustainable approach. Hymenoptera Chalcidoidea includes natural enemies of scale insects that have been successfully used in many biological control programs. However, the correct identification of pest scale species and their natural enemies is particularly challenging because these insects are very small and highly specialized. Integrative taxonomy, coupling DNA barcoding and morphological analysis, has been successfully used to characterize pests and natural enemy species. In this study, we performed a survey of parasitoids and predators of armored and soft scales in Chile, based on 28S and COI barcodes. Fifty-three populations of Diaspididae and 79 populations of Coccidae were sampled over the entire length of the country, from Arica (18°S) to Frutillar (41°S), between January 2015 and February 2016. The phylogenetic relationships obtained by Bayesian inference from multilocus haplotypes revealed 40 putative species of Chalcidoidea, five Coccinellidae and three Neuroptera. In Chalcidoidea, 22 species were identified morphologically, resulting in new COI barcodes for 12 species and new 28S barcodes for 14 species. Two predator species (Rhyzobius lophantae and Coccidophilus transandinus) were identified morphologically, and two parasitoid species, Chartocerus niger and Signiphora bifasciata, were recorded for the first time in Chile.

Abstract The mango tree (Mangifera indica L.), native to Asia, is expanding in Brazil. However, research related to phytophagous organisms and natural enemies associated with this fruit are scarce in the country. The aim of this work was to report new species of thrips-pest and natural enemies associated with mango tree inflorescence. The work was carried out in a Tommy Atkins mango orchard located in the municipality of Jardinópolis, São Paulo, Brazil. The arthropods found in malformed inflorescences were collected and identified. Frankliniella gemina Bagnall, Frankliniella distinguenda Bagnall (Thysanoptera: Thripidae) and Haplothrips gowdeyi (Franklin) (Thysanoptera: Phlaeothripidae) thrips-pest species were recorded for the first time associated with inflorescence in mango orchards. The predators were collected in association with the phytophagous thrips.

Abstract The cotton mealybug, Phenacoccus solenopsis Tinsley (Hemiptera: Pseudococcidae) is a polyphagous sap sucking insect with a wide geographical and host range causing severe losses in economically important crops. This study represents the first record of P. solenopsis as a new insect attacking cotton plants (Gossypium barbadense var. Giza 86) in Kafr El-Sheikh governorate, Egypt. The insect was noticed on cotton plants for the first time during its growing season of 2014. The mealybug specimens were collected from infested cotton plants and identified as P. solenopsis. In an attempt to control this pest, eight toxic materials viz., imidacloprid, thiamethoxam, flonicamid, emamectin-benzoate, chlorpyrifos, methomyl, deltamethrin and mineral oil (KZ-oil), belonging to different chemical groups, were tested for their influence against P. solenopsis on cotton under field conditions. Methomyl, imidacloprid, thiamethoxam and chlorpyrifos showed the highest efficacy against P. solenopsis recording 92.3 to 80.4% reduction of the insect population. Flonicamid, emamectin-benzoate and KZ-oil failed to exhibit sufficient P. solenopsis control.
