“…Eastop (1966) mentions two species of Pineus in Australia: Pineus pini Gmelin, 1790 on Pinus sylvestris L. and P. laevis on P. radiate. These species are not easily distinguished and perhaps both might be P. boerneri.…”

Pineus boerneri Annand, 1928 (Hemiptera, Adelgidae) _ a new species to Brazil: morphology of eggs, nymphs and adults. Pineus boerneri represents the first Adelgidae species recorded in Brazil. This aphid species forms extensive colonies on branches and trunk of Pinus spp., with apterous oviparous females, eggs and nymphs covered with white wax. The aim of this research is to study the morphology of eggs, nymphs, and adults to provide useful data for species identification in order to solve taxonomic issues. The study was based on morphometric data and optical and scanning electron microscopy images. First instar nymphs are active and can be easily distinguished from the others by their elongate minute yellowish body; well developed legs bearing a pair of sensorial setae at the apex of the second tarsomere; and antenna with three segments with a large rhinarium and distinct apical setae on the last segment. From the second to the fourth instar, nymphs are sessile, with round red body; they loose the third antennal segment and its sensorial structures, as well as the setae on the second tarsomere. The oviparous female is reddish-brown, with round body with about 0.76 mm diameter; legs reduced; antennae one-segmented; ovipositor distinct; numerous wax glands are present, mainly on the head. Accurate characterization of the species and distinction of the nymphal instars of P. boerneri were made possible by canonical analysis of morphometric data and morphological characters.
Pineus boerneri Annand, 1928 (Hemiptera, Adelgidae) _ uma espécie nova para o Brasil: morfologia de ovos, ninfas e adultos. Pineus boerneri representa a primeira espécie de Adelgidae registrada no Brasil. Esta espécie de Adelgidae forma densas colônias em ramos e tronco de Pinus spp., com fêmeas ovíparas ápteras, ovos e ninfas recobertos por lanugem branca. A presente pesquisa teve como objetivo estudar a morfologia de ovos, ninfas e de fêmeas adultas, visando à identificação correta da espécie, para solucionar problemas taxonômicos. O estudo das formas baseou-se na morfometria e microscopia ótica e eletrônica de varredura. As ninfas de primeiro instar são ativas, de coloração amarelada, diferenciadas das demais pelo formato alongado do corpo; pernas bem desenvolvidas com um par de cerdas sensoriais no ápice do segundo segmento tarsal; antenas com três segmentos, com um rinário e cerdas apicais bem distintas. A partir do segundo instar, as ninfas são sésseis, apresentam corpo arredondado de coloração avermelhada, perdem o terceiro segmento antenal e as cerdas e estruturas sensoriais do segundo segmento tarsal. As fêmeas adultas são marrom-avermelhadas, apresentam corpo arredondado, com aproximadamente 0,76 mm de diâmetro; pernas reduzidas; um único segmento antenal bem reduzido; ovipositor distinto; e numerosas glândulas de cera, principalmente, na região da cabeça. A caracterização da espécie e distinção dos ínstares é possível pela análise canônica dos dados morfométricos e caracteres morfológicos

“…There is also general agreement as to the criteria for the subdivision of this subfamily into the tribes Macrosiphini and Aphidini and the further subdivision of the tribe Aphidini into the subtribes Rhopalosiphina and Aphidina (Bomer 1952;Eastop 1966;Shaposhnikov 1964).…”

Melanaphis sacchari (Zehntner;Hemiptera: Aphididae), sugarcane aphid (SCA), is an invasive phloem‐feeder found worldwide with a wide host range of economically important plants including sorghum and sugarcane. Given its high reproductive capacity and ability to rapidly spread over long distances, SCA presents challenges for effective control, leading to substantial economic losses. Recent studies have identified two multiloci SCA genotypes specialized in feeding on sugarcane (MLL‐D) and sorghum (MLL‐F) in the USA, which raises concerns as the USA is the second largest sorghum‐producing country. This has encouraged research towards identifying these two biotypes where some research has stated them as two species; MLL‐D clade to be M. sacchari and MLL‐F clade to be M. sorghi Theobald (Hemiptera: Aphididae), sorghum aphid (SA). This review aims at compiling research progress that has been made on understanding the SCA/SA species complex. Furthermore, this review also highlights a wide range of management strategies against SCA/SA that includes both biological and chemical methods. In addition, the review emphasizes studies examining host plant resistance to understand and evaluate the role of R‐genes and phytohormones such as jasmonic acid, salicylic acid and ethylene against SCA. Beside this, plant volatiles and other secondary metabolites such as flavonoids, terpenes and phytanes are also explored as potential control agents. Being an invasive pest, a single management tactic is inadequate to control SCA population and hence, integrated pest management practices incorporating physical, cultural and biological control methods should be implemented with exclusive chemical control as a last resort, which this review examines in detail. © 2024 The Author(s).
