Modeling the Distribution of the Invasive Alien Cycad Aulacaspis Scale in Africa Under Current and Future Climate Scenarios.

The cycad aulacaspis scale, Aulacaspis yasumatsui Takagi (Hemiptera: Coccoidea: Diaspididae), is native to Southeast Asia but an invasive pest of the gymnosperm order Cycadales in many parts of the world. Aulacaspis yasumatsui was recently reported on the cycad genus Encephalartos in South Africa and is currently categorized as a 'prohibited terrestrial invertebrate' in the invasive species legislation, National Environmental Management: Biodiversity Act, 2004 (NEM:BA). Encephalartos is endemic to Africa, and 11 species are listed as critically endangered and four species as endangered.

Effect of Temperature and CO2 on Population Growth of South American Tomato Moth, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae) on Tomato.

The effects of different temperatures (26, 28, 30, and 32°C) and CO2 concentrations (380 and 550 ppm) on the life table of Tuta absoluta were evaluated. The life history raw data of T. absoluta were analyzed by using the age-stage, two-sex life table.
