Eleven morphometric measurements were performed according to Foottit et al (2010), i.e.…”

“…In this study, there were some morphometric characters of aphids infesting bananas were studied using multivariate analysis and t-test to get accurate identification to confirm morphological identification keys by Blackman & Eastop (2006) and Miller et al (2014). In addition, we also conducted the host plants survey of aphids infesting banana to collect appropriate data for the purpose of developing a strategy of controlling banana aphids and BBTV.…”

“…Furthermore, the host range of the two species is slightly different. P. nigronervosa mostly feeds on banana and occasionally feeds on Heliconia species (Nordam, 2004;Bhadra & Agarwala, 2010;Foottit et al, 2010;Suparman et al, 2011;Miller et al, 2014), whereas P. caladii feeds on Alocasia sp., Caladium sp., Elettaria sp., Hedychium sp., Xanthosoma sp., and Zingiber sp. (Nordam, 2004;Miller et al, 2014).…”

“…Due to the most recent taxonomy of banana aphids, it is necessary to update the status of banana aphids in Indonesia, including in Java. The two cryptic species, P. nigronervosa and P. caladii, are only distinguished by the ultimate rostrum segment (URS) in which the URS of P. caladii is shorter than P. nigronervosa (Nordam, 2004;Foottit et al, 2010;Miller et al, 2014). Multivariate analysis approach on morphometric of aphids has been used by some authors to investigate morphological variation within and between populations of aphids (Blackman, 1987;Foottit et al, 2010).…”

Banana aphid, Pentalonia nigronervosa Coquerel (Hemiptera: Aphididae) is known as vector of Banana bunchy top virus (BBTV) that threatening production of banana worldwide. It was reported recently that P. nigronervosa and P. caladii is “cryptic species”. A good and proper identification is necessary to verify the correct species and its status. Research was conducted to identify and to find the host range of banana aphids in Java. Aphid collection was conducted in several locations in West Java, Central Java, and East Java. Eleven morphometric characters were analyzed to assess the morphometric variations among banana aphids. Morphological identification and principle component analysis (PCA) approach were conducted for accurate identification of banana aphids. Two species of aphids were found during the survey in Java, i.e. P. nigronervosa and P. caladii. P. nigronervosa mostly infested bananas (Musa spp.), and a few was found on heliconia (Heliconia sp.) and banana traveler (Ravenala madagascariensis). In contrast, P. caladii generally infested taro (Colocasia esculenta), turmeric (Curcuma longa), costus (Costus sp.), dumbcane (Dieffenbachia sp.), but rarely on bananas.

“…Insetos, como lagartas, cochonilhas e pulgões, já foram relatados associados a rosa do deserto. Dentre eles, a lagarta Daphnis nerii L. (Lepidoptera: Sphingidae) foi relatada em Taiwan (LIN, 1997), a cochonilha Parasaissetia nigra (Nietner) (Hemiptera: Coccoidea: Pseudococcidae) no território da União Européia (EFSA, 2013), e o pulgão Aphis nerii Boyer (Hemiptera: Aphididae) na região da Micronésia (MILLER et al, 2014).

Resumo: A rosa do deserto, Adenium obesum (Forssk.) Roem. & Schult, é uma planta ornamental da família Apocynaceae, de elevado valor comercial, que é empregada na ornamentação de jardins, praças e áreas públicas. A rápida expansão dessa espécie propiciou um ambiente favorável para sua colonização por diversas espécies de insetos e ácaros em novas regiões de introdução. Dessa forma, objetivou-se com este estudo relatar a ocorrência e injúrias ocasionadas por insetos fitófagos em A. obesum. Assim, foram realizadas observações entre o período de agosto e outubro de 2012, em plantas de rosa do deserto, empregadas no paisagismo da Universidade Federal de Goiás. A coleta foi realizada aleatoriamente, sendo os insetos armazenados em recipientes de vidro contendo etanol 70%, seguindo para identificação por taxonomistas da área. Foram identificadas duas espécies de cochonilhas: Hemiberlesia rapax Comstock (Hemiptera: Diaspididae), Parasaissetia nigra (Nietner) (Hemiptera: Coccoidea: Pseudococcidae) e o pulgão Aphis nerii Boyer (Hemiptera: Aphididae), ocasionando injúrias nas folhas, flores e no caule da rosa do deserto. Durante as observações, verificou-se a presença de inimigos naturais de A. nerii, como parasitoides, em razão da presença de múmias (indivíduos parasitados), e também de predadores como crisopídeos, coccinelídeos e sirfídeos. Este é o primeiro relato de ocorrência de H. rapax em A. obesum. Palavras-chave -Injúria. Insetos sugadores. Planta ornamental. Abstract:The desert rose, Adenium obesum (Forssk.) Roem. & Schult, is an ornamental plant of the Apocynaceae family with high commercial value, that is used in the ornamentation of gardens, squares and public areas. The rapid expansion of the species has provided a favourable environment for its colonisation by several species of insects and mites in the new regions where it was introduced. The aim of this study was to report the occurrence of, and injuries caused by, phytophagous insects in A. obesum. Observations were made from August to October 2012 in plants of the desert rose used in landscaping at the Federal University of Goias. The samples were collected randomly, and the insects stored in glass containers containing 70% ethanol and forwarded for identification by taxonomists in the area. Two species of cochineals were identified: Hemiberlesia rapax Comstock (Hemiptera: Diaspididae) and Parasaissetia nigra (Nietner) (Hemiptera: Coccoidea: Pseudococcidae), and the oleander aphid Aphis nerii Boyer (Hemiptera: Aphididae), which were damaging the leaves, flowers and stem of the desert rose. During the observations, natural enemies of A. nerii, such as parasitoids, were found due to the presence of mummies (parasitised individuals), as well as predators, such as chrysopidae, coccinellidae and Syrphidae. This is the first report of H. rapax occurring in A. obesum.

Landscape-level bird loss increases the prevalence of honeydew-producing insects and non-native ants

Bird exclusion experiments consistently show that birds exhibit strong top-down control of arthropods, including ants and the honeydew-producing insects (HPIs) that they tend. However, it remains unclear whether the results of these small-scale bird exclosure experiments can be extrapolated to larger spatial scales. In this study, we use a natural bird removal experiment to compare the prevalence of ants and HPIs between Guam, an island whose bird community has been extirpated since the 1980s due to the introduction of the brown tree snake, and two nearby islands (Rota and Saipan) that have more intact bird assemblages. Consistent with smaller-scale bird exclosure experiments, we show that (1) forest trees from Guam are significantly more likely to host HPIs than trees from Saipan and (2) ants are nearly four times as abundant on Guam than on both Saipan and Rota. The prevalence of HPIs varied slightly based on tree species identity, although these effects were not as strong as island-level effects associated with bird loss. Ant community composition differed between Guam and the other two islands. These results corroborate past observational studies showing increased spider densities on Guam and suggest that trophic changes associated with landscape-level bird extirpation may also involve alterations in the abundance of ants and HPIs. This study also provides a clear example of the strong indirect effects that invasive species can have on natural food webs.Electronic supplementary materialThe online version of this article (10.1007/s00442-018-4273-5) contains supplementary material, which is available to authorized users.
