Alimentary canal and reproductive tract of Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae, Scolytinae) Neotropical Entomology
Rubio G.,José D.; Bustillo P.,Alex E.; Vallejo E.,Luis F.; Acuña Z.,José R.; Benavides M.,Pablo.
The alimentary canal and the reproductive tract of males and females of Hypothenemus hampei Ferrari are described. The alimentary canal of H. hampei showed the crop with several spine-like structures and the midgut with few gastric caeca. We evidenced for the first time that adult females need to feed on coffee in order to produce viable eggs before and during oviposition period. The presence of air bubbles inside the anterior midgut may be due to starvation rather than the response of the environment during flying as previously reported. Two ovaries and the same structures and arrangements common to individuals of the Curculionidae beetles composed the female reproductive system. The male reproductive tract showed a significant difference with respect to...

Arbuscular mycorrhizal colonization in Asteraceae from white sand savannas, in Pinar del Río, Cuba Biota Neotropica
Rodríguez-Rodríguez,Raquel Milagros; Herrera,Pedro; Furrazola,Eduardo.
Asteraceae family shows a great diversity in Cuba and presents threatened taxons in high number. Pinar del Río has 19 threatened species belonging to this family and three of them are characteristic of a sandy (quartzitic) soil at the Reserva Florística Manejada San Ubaldo-Sabanalamar (Floristic Reserve San Ubaldo-Sabanalamar). The arbuscular mycorrhizal status and colonization rate in Aster grisebachii, Erigeron bellidiastroides, Erigeron cuneifolius, Pectis juniperinaand Sachsia polycephala (Asteraceae) from this Reserve was determined in October 2009 and April 2010, during hydrologic rainy and dry period, respectively. All species were mycotrophic in both periods with a high percentage of colonization rates, between 66 and 100% in rainy period and...

Clearing and dissecting insects for internal skeletal morphological research with particular reference to bees Rev. Bras. entomol.
Porto,Diego Sasso; Melo,Gabriel A.R.; Almeida,Eduardo A.B..
ABSTRACT A detailed protocol for chemical clearing of bee specimens is presented. Dry specimens as well as those preserved in liquid media can be cleared using this protocol. The procedure consists of a combined use of alkaline solution (KOH or NaOH) and hydrogen peroxide (H2O2), followed by the boiling of the cleared specimens in 60–70% EtOH. Clearing is particularly useful for internal skeletal morphological research. This procedure allows for efficient study of internal projections of the exoskeleton (e.g., apodemes, furcae, phragmata, tentoria, internal ridges and sulci), but this process makes external features of the integument, as some sutures and sulci, readily available for observation as well. Upon completion of the chemical clearing process the...

Radiographic images and relationship of the internal morphology and physiological potential of broccoli seeds Agronomy
Abud, Haynna Fernandes; Cícero, Silvio Moure; Gomes Junior, Francisco Guilhien.
 Image analysis using X-rays is an efficient technique for assessing the seed quality of several species, presenting itself as a rapid response method that is simple to execute, reproducible and non-destructive. Thus, this research adjusted a methodology that aims to relate the internal morphology of broccoli seeds to their physiological potential through radiographic analysis of seeds and computerized images of seedlings. The broccoli cultivars used were Piracicaba Precoce and Ramoso Santana represented by ten lots of each one. The study was conducted using X-ray imaging for seed analysis, in which the area, density and circularity measures were obtained as internal morphology characteristics of seeds. After a germination test, the seedling length was...

Seed weight of Xylopia aromatica (Annonaceae): quality evaluation from X-ray and seedling emergence Scientia Agricola
Socolowski,Fábio; Cicero,Silvio Moure; Vieira,Daniela Cristine Mascia.
Xylopia aromatica (Lam.) Mart. (Annonaceae) is a native species of the Brazilian Savannah (“Cerrado”) region, recommended for the recovery of degraded areas and also for medicinal use. Seeds of some species of the Annonaceae require a long period to germinate and many studies have focused on determining methods which can rapidly analyze seed quality. The objective of this study was to evaluate the quality of Xylopia aromatica (Lam.) Mart. seeds in accordance to their weight, through X-ray images and emergence test. Seeds were collected from dehiscent follicles with a blower and one portion was separated into weight categories: very light seeds, light seeds and heavy seeds. Another seed portion was separated in water by their density, into those that sank...
