New Data on the Whiteflies (Insecta: Hemiptera: Aleyrodidae) of Montenegro, Including Three Species New for the Country
Acta entomologica serbica, 2015, 20: 29-41 UDC 595.754(497.16)"2012" DOI: 10.5281/zenodo.44654 NEW DATA ON THE WHITEFLIES (INSECTA: HEMIPTERA: ALEYRODIDAE) OF MONTENEGRO, INCLUDING THREE SPECIES NEW FOR THE COUNTRY CHRIS MALUMPHY1, SANJA RADONJIĆ2, SNJEŽANA HRNČIĆ2 and M ILORAD RAIČEVIĆ2 1 The Food and Environment Research Agency, Sand Hutton, YO41 1LZ, United Kingdom E-mail: [email protected] 2 Biotechnical Faculty of the University of Montenegro, Podgorica, Montenegro Abstract Collection data on nine species of whitefly collected in the coastal and central regions of Montenegro during October 2012 are presented. Three species are recorded from Montenegro for the first time: Aleuroclava aucubae (Kuwana), Aleurotuba jelinekii (Frauenfeld) and Bemisia afer (Priesner & Hosny) complex. Two of the species, A. aucubae and B. afer complex were found in Tološi, on Citrus sp. and Laurus nobilis, respectively. Aleurotuba jelinekii was found in Podgorica on Viburnum tinus. KEY WORDS: Whiteflies, Aleyrodidae, Montenegro Introduction Whiteflies comprise a single family, Aleyrodidae, which currently contains 1556 extant species in 161 genera (Martin & Mound, 2007). Fifty-six species occur outdoors in Europe and the Mediterranean basin (Martin et al., 2000). All whiteflies are phytophagous and have three developmental stages: egg, larval (with four larval instars) and adult. Many species are economically important plant pests of outdoor crops, ornamentals and indoor plantings. Feeding by immature whiteflies reduces plant vigor by depletion of plant sap, and foliage becomes contaminated with eliminated honeydew on which black sooty mold grows, thereby reducing the photosynthetic area and lowering the aesthetic appearance of ornamentals. Adults of a small number of species, most notably Bemisia tabaci (Gennadius), are important vectors of plant viruses (Jones, 2003). -

Dwarf-Cashew Resistance to Whitefly (Aleurodicus Cocois) Linked To
Research Article Received: 12 February 2019 Revised: 14 June 2019 Accepted article published: 25 June 2019 Published online in Wiley Online Library: 27 July 2019 (wileyonlinelibrary.com) DOI 10.1002/ps.5531 Dwarf-cashew resistance to whitefly (Aleurodicus cocois) linked to morphological and histochemical characteristics of leaves Elaine SS Goiana,a Nivia S Dias-Pini,a* Celli R Muniz,a Arlete A Soares,b James C Alves,b Francisco C Vidal-Netoa and Cherre S Bezerra Da Silvac Abstract BACKGROUND: The cashew whitefly (CW), Aleurodicus cocois, is an important pest of cashew in Brazil. The use of resistant plants may be an effective strategy for the control of this pest. In a preliminary assay, we found that dwarf-cashew clones show different levels of resistance to CW. Here, we hypothesized that such resistance is associated with morphological characteristics of cashew leaves and their content of phenolic compounds. RESULTS: We determined (i) the attractiveness and suitability for oviposition of five dwarf-cashew clones towards CW, (ii) the leaf morphology and chemistry of those clones, and (iii) the relationship between leaf characteristics and resistance to CW. In greenhouse multiple-choice assays, PRO143/7 and CCP76 showed, respectively, the lowest and highest counts of both CW adults and eggs. Scanning electron microscopy (SEM) analysis revealed that PRO143/7 and EMBRAPA51 have, respectively, the highest and lowest numbers of leaf glandular trichomes. We found a negative correlation between number of trichomes in the abaxial surface of cashew leaves and CW oviposition. In addition, confocal microscopy analysis and histochemical tests with ferrous sulfate indicated a higher accumulation of phenolic compounds in the resistant clone PRO143/7 relative to the other clones. -

E-mail: [email protected]. Accepted 26 November, 2009 The developmental biology of Aleurodicus dispersus Russel., have been investigated. It was found to have a cumulative developmental period of (23 - 41) days. The mean numbers of egg developing to adult have been found to be 138.1 per thousand eggs. The spread of the insect have been found to be connected to human traffics. The oviposition and feeding occurs simultaneously and occur more on their abaxial surface of host leaves. Rainfall and temperature play a prominent role on the abundance and seasonal fluctuation of the insect and infact, regulating their population. Presently, A. dispersus is found on arable as well as ornamental plants but rarely on gramminae. At present, A. dispersus is a minor pest with the potential of becoming a serious pest with the increasing global warming.

The RSW life cycle was shorter on coconut compared to that of banana and Indian shot plant. Thus coconut is preferred hosts for its growth and development. A fecundity of 49.50± 4.09 and total duration of the nymphal instars being of 23.2± 1.38 days. Duration to lifestages on banana was less under field conditions as compared to that under caged conditions.These results on the comparative biology and growth will help to develop suitable IPM strategies for this invasive pest.

SCIENTIFIC NOTES / NOTAS CIENTÍFICAS IDESIA (Chile) 2018 Voltinism of Aleurothrixus floccosus Maskel (Hemiptera: Aleyrodidae) in an oasis agroecosystem in the Atacama Desert, Tarapacá Region, Chile Voltinismo de Aleurothrixus floccosus Maskel (Hemiptera: Aleyrodidae) en un agroecosistema de oasis en el Desierto de Atacama, Región de Tarapacá, Chile Víctor Tello¹*, Osman Peralta¹, Tommy Rioja¹ ABSTRACT The number of generations of woolly whitefly [Aleurpthrixus floccosus (Maskell)] was determined on sweet orange orchards [Citrus sinensis (L.) Osbeck] in the Pica Oasis, Tarapacá Region, Chile. The essays lasted one year, from April 2010 to April 2011. Woolly whitefly presented 7 generations in the Pica Oasis, which overlap causing the constant presence of this pest in Pica. In the coldest months (autumn-winter) the cycle tends to be longer (65.5 days), while in the warmer months (spring-summer) the cycle lasts 45.5 days. In general, the cycle is completed at 52 days. Keywords: Generations, woolly whitefly, citrus, Pica. RESUMEN Se determinó el número de generaciones de la mosca blanca algodonosa de los cítricos [Aleurothrixus floccosus (Maskell)] en huertos de naranja dulce [Citrus sinensis (L.) Osbeck] en el Oasis de Pica, Región de Tarapacá, Chile. Los ensayos tuvieron una duración de un año, desde abril del 2010 hasta abril de 2011. La mosca blanca de los cítricos presentó 7 generaciones en el Oasis de Pica, cuyos estadios se superponen causando la presencia constante de esta plaga en Pica. En los meses más fríos (otoño-invierno) el ciclo tiende a ser más largo (65,5 días), mientras que en los meses más cálidos (primavera-verano) el ciclo dura 45,5 días.
