The Cuba-Florida Plant-Pest Pathway, Cory Penca, Damian C. Adams, Jiri Hulcr Jan 2016

The Cuba-Florida Plant-Pest Pathway, Cory Penca, Damian C. Adams, Jiri Hulcr

Insecta Mundi

Recent shifts in US policies towards Cuba suggest a relaxation or lifting of the embargo may occur in the

near future. With the prospects of open travel and trade with Cuba come concerns over the introduction of agricultural

pests. In an effort to assess these concerns the distribution-based introduction risk of pests listed in the 2015 Cooperative

Agricultural Pest Survey’s (CAPS) list of priority pests of economic and environmental importance is reviewed. Of

the 59 pests on the CAPS priority pest list, 20 have been recorded in the literature as being present in the Caribbean

Basin, South America and Central …

Scale Insects (Hemiptera: Coccoidea) Associated With Avocado Crop, Persea Americana Mill. (Lauraceae) In Valle Del Cauca And Neighboring Departments Of Colombia, Takumasa Kondo, Jazmín Adriana Muñoz

Insecta Mundi

Abstract. Scale insects (Hemiptera: Coccoidea) of avocado, Persea americana Mill. (Lauraceae) were collected in the State of Valle del Cauca, Colombia. The study was conducted for one year, during October 2008–October 2009. As a result of this study, 34 scale insect species in seven families (Coccidae, Diaspididae, Kerriidae, Margarodidae, Monophlebidae, Pseudococcidae and Putoidae) were collected. Together with previous records, the number of scale insects collected on avocado in Colombia increased to 44 species and to 137 species worldwide. Species commonly collected on avocado in Colombia include Hemiberlesia cyanophylli (Signoret), Pseudoparlatoria parlatorioides (Comstock) (Diaspididae), Ceroplastes rubens Maskell, Coccus hesperidum L., Protopulvinaria …

Pyroghatsiana: A New Genus Of Fire-Colored Beetles (Coleoptera: Pyrochroidae: Pyrochroinae) From The Southern Ghats, India, Daniel K. Young

Insecta Mundi

Pyroghatsiana, a new genus of pyrochroine Pyrochroidae is described from the Southern Ghats of the Indian continental southern tip.

Absence Of Mate Choice And Postcopulatory Benefits In A Species With Extreme Sexual Size Dimorphism, Marie-Claire Chelini, Eileen A. Hebets Jan 2016

Absence Of Mate Choice And Postcopulatory Benefits In A Species With Extreme Sexual Size Dimorphism, Marie-Claire Chelini, Eileen A. Hebets

Eileen Hebets Publications

Most hypotheses related to the evolution of female-biased extreme sexual size dimorphism (SSD) attribute the differences in the size of each sex to selection for reproduction, either through selection for increased female fecundity or selection for male increased mobility and faster development. Very few studies, however, have tested for direct fitness benefits associated with the latter – small male size. Mecaphesa celer is a crab spider with extreme SSD, whose males are less than half the size of females and often weigh 10 times less. Here, we test the hypotheses that larger size in females and smaller size in males …
