Biological responses of aphids (Hemiptera: Aphididae) when fed three species of forage grasses Heloise A. Parchen1 and Alexander M. Auad2,* Abstract In Brazil, the forage species Brachiaria spp., Pennisetum purpureum (Schumacher), and Cynodon dactylon (L.) (Poaceae) are important components in the feed that is used to rear animals for meat and milk production. Aphids are among the insects that feed on these forage species and, at high population levels, greatly reduce the amount and quality of forage.

The list includes records before 1992, which have been published in previous papers, as well as data from an almost ten-year survey using Rothamsted suction traps and Moericke traps. The recorded aphidofauna consisted of 301 species. The family Aphididae is represented by 13 subfamilies and 120 genera (300 species), while only one genus (1 species) belongs to Phylloxeridae. The aphid fauna is dominated by the subfamily Aphidi- nae (57.1 and 68.4 % of the total number of genera and species, respectively), especially the tribe Macrosiphini, and to a lesser extent the subfamily Eriosomatinae (12.6 and 8.3 % of the total number of genera and species, respectively).

TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000).

CAMERON STOREY (Under the Direction of Alan Harvey) ABSTRACT Water lily aphids, Rhopalosiphum nymphaeae, are a polyphagous species of insect that feed on a variety of host plants including members of the Lemnaceae family. Many studies have focused on the relationship between herbivore preference and performance on different host plants, and as such the goal of this study was to determine if there is any relationship between host plant preference and performance of the water lily aphid on three different species of duckweed, including one invasive duckweed. Aphid preference was determined through a series of choice tests, which showed that the aphids preferred Spirodela polyrhiza over Landoltia punctata over Lemna minor.

It is thought this phenomenon is caused by an inverse seasonal relationship in abundance operating between spring and autumn of each year. It has been hypothesised that the underlying mechanism of this process is due to a plant factor, intra-specific competition between aphids, or a combination of the two. This thesis examines the population dynamics and the life-history characteristics of D. platanoidis, with an emphasis on elucidating the factors involved in driving the dynamics of the aphid population, especially the role of bottom-up forces. Manipulating host plant quality with different levels of aphids in the early part of the year, showed that there was a contrast in aphid performance (e.g. duration of nymphal development, reproductive duration and output) between the first (spring) and the third (autumn) aphid generations. This indicated that aphid infestation history had the capacity to modify host plant nutritional quality through the year. However, generalist predators were not key regulators of aphid abundance during the year, while the specialist parasitoids showed a tightly bound relationship to its prey. The effect of a fungal endophyte infecting the host plant generally showed a neutral effect on post-aestivation aphid dynamics and the degree of parasitism in autumn.
