Abstract:
Field screening of seven cultivars of cabbage namely: Green Crown, Green Top, Green Coronet, Pioneer, Nepa Round, Copenhagen Market and Golden Acre were carried out against cabbage butterfly (Pieris brassicae) and cabbage aphid (Brevicoryne brassicae) at the research farm of entomology section, Gokuleshwor Agriculture and Animal Science College, Baitadi in RCBD design from October 2017 to February 2018. Five plants were tagged randomly after transplanting in field excluding border plants in each plot. Data were collected for the population dynamics of cabbage butterfly larvae and cabbage aphid on weekly basis. None of the seven cultivars were found resistant to cabbage butterfly and cabbage aphid, however their population density varied on tested cultivars. Cabbage butterfly population was recorded the highest on the cultivar Pioneer (22.88 larvae/plant) and the lowest on the cultivar Copenhagen Market (10.06 larvae/plant), and other cultivars were of intermediate types. Similarly, the population density of aphid ranged from 36.70 to 105.58 aphids/leaf. The highest population density of aphid was recorded on cultivar Green Crown (105.58 aphids/leaf) and the lowest on cultivar Copenhagen Market (39.82 aphids/leaf. From the results, Copenhagen Market proved to be the best against both cabbage butterfly and cabbage aphids.

Abstract:
Evidence is accumulating that climate change is having a significant effect on a wide range of organisms spanning the full range of biodiversity found on this planet. This study investigates the ecological role of climate change, the North Atlantic Oscillation (NAO) and habitat change on British insect populations. Despite the NAO having a considerable effect on British weather, the role of the NAO on British insects has not previously been studied in great detail. The World's two best entomological time series datasets were used – the United Kingdom Butterfly Monitoring Scheme (UKBMS) and the Rothamsted Insect Survey of aphids – both surveys with very large sample sizes and high quality data. Summary of main findings: 1. Warm weather associated with a positive NAO index caused the spring migration of the green spruce aphid (Elatobium abietinum), a pest species of spruce trees (Picea) to start earlier, continue for longer and contain more aphids. An upward trend in the NAO index during the period 1966-2006 is associated with an increasing population size of E. abietinum. 2. The NAO does not affect the overall UK butterfly population size. However, the abundance of bivoltine butterfly species, which have a longer flight season, were more likely to respond positively to the NAO compared to univoltine species, which show little or a negative response. 3. A positive winter NAO index was associated with warmer weather and earlier butterfly flight dates. For bivoltine (two generations in a year) species, the NAO affects the phenology of the first generation, and then the timing of the second generation is indirectly controlled by the timing of the first generation. The NAO influences the timing of the butterfly flight seasons more strongly than it influences population size. 4. Butterfly data from Monks Wood National Nature Reserve in Cambridgeshire showed that the NAO does not affect the abundance of the whole butterfly community, but it does affect the population size of some species. The NAO does not affect butterfly diversity, but there were decreases in butterfly diversity and number of species with time. 5. The total number of butterflies counted at Monks Wood was constant for most of the time series. However, the population size of the ringlet (Aphantopus hyperantus) increased from very low numbers to more than half the total number of butterflies counted each year. Therefore the total population size of all the other species has decreased considerably. 6. The NAO was more important than climate change in determining the flight phenology of the meadow brown butterfly (Maniola jurtina) at Monks Wood. In conclusion, the NAO affects the abundance of some species of British butterfly, and an aphid species, with a stronger effect on the timing of flight rather than abundance. There was evidence for a long-term decrease in the biodiversity of butterflies at Monks Wood and this decrease is likely to continue.

Abstract:
This thesis focuses on a question central to the field of evolutionary ecology; how variation is maintained within populations. Focusing on a model system based around the pea aphid (Acyrthosiphon pisum) I reveal substantial levels of genetic variation in every fitness related trait examined. Theory suggests that such variation may commonly be maintained by life-history trade-offs operating between different traits, but experimental examples of these traits are exceedingly rare within the literature. Populations of the pea aphid show high levels of variation in the ability to successfully defend against natural enemy attack, and to date this reason for this prolonged variation has remained unexplained.

Abstract:
The evolution of species interactions is a fascinating subject, and one of vital importance if we are to understand how biological communities change over time. This thesis considers the interaction between aphids (Homoptera) and ants (Formicidae). Ants tend aphids for sugary honeydew and in return provide a variety of protective services. A literature review in Chapter 1 introduces the subject and provides background information. Chapter 2 considers ant- aphid interactions in a community setting. Specifically, I consider the fitness effects of the ant- aphid interaction on host plants. Net benefits or costs to plants depend on the densities of ants and aphids; these densities may themselves change depending on context dependent factors. Chapters 3 and 4 consider how semiochemicals can allow species to respectively maintain or avoid synchrony in space and time with mutualists or antagonists. Chapter 3 shows ladybirds avoid prey patches guarded by ants by reducing oviposition in response to ant semiochemicals. Chapter 4 shows that aphid walking dispersal can be limited by ant semiochemicals. This may be adaptive for aphids to remain in areas of enemy- free space. Alternatively, if levels of kin competition are high limited dispersal could be costly to aphids. In Chapter 5 I consider interactions between invasive and native ants. Ecological dominance in ants may be mediated by the ability to monopolise honeydew- producing resources. Chapter 6 explores ants’ decisions whether to tend or prey upon aphids. Predation of aphids depends on colony demand (e.g. through cues from the presence of larvae) as well as the quality or quantity of supply (e.g. increased predation of unproductive aphids). Finally, Chapter 7 deals with macroevolutionary patterns in the interaction between ants and aphids. Specifically, I identify ecological traits that characterise aphid- tending ants. A final discussion chapter summarises how ant-aphid interactions fit into existing mutualism theory.

Abstract:
The pea aphid (Acyrthosiphon pisum) was one of the first aphid species for which different biotypes were described. Subsequently, the differences between biotypes were found to be consistent in time and space and several of them were given subspecies status. The differences between the subspecies is mainly ecological, their use of certain plants (the so-called marker hosts). There are hardly any differences in the morphology of the subspecies with the exception of that from Restharrow (Ononis spec. ). The performance and survival of aphids on several host plants were used to determine the degree of separation between the pea aphid subspecies and their marker hosts. To confirm the genetic basis of the host plant relations of the subspecies they were crossed. Few of the crosses showed hybrid dysfunction. The performance and survival of the hybrid clones confirmed that host plant relationships were genetically determined. There was also indication of a trade off. However, there was no indication that "Hopkin's host selection principle" played a big role in the utilisation of non-preferred host plants, with possible exception of clover. The different taxa differ significantly in body sizes. Clones from crop plants were generally bigger than those from wild plants. The genetic component of the size difference accounted for nearly 50 percent of the variances in size in wild clones. By comparing the performance of reciprocal crosses between subspecies on the marker hosts of the parents, no evidence was found that the specialised symbionts are specialised for particular marker hosts. This indicates that the aphid's genotype is the main determinant of host plant usage in the pea aphids. Furthermore, these aphids prefer their respective marker hosts. The connection between preferencea ndp erformancew as partly broken by hybridising the subspecies. The only subspecies that produces winged males and therefore has the ability to colonise other host plants, and thus the opportunity to mate with females of other subspecies, preferred sexual females of its own subspecies. The separation of the subspecies is further enhanced by the behaviour of egg laying females, which preferred to oviposit on their marker hosts. Hatching time of the eggs was also associated with the ecology of their marker host plants and probably the life history of the aphid, i.e. the subspecies that host alternates hatched first. The ecological separation between the subspecies was not confirmed by a molecular analysis, which even failed to separate the morphologically distinct subspecies from Ononis from the others taxa. The pea aphid complex is a good example of sympatric taxa, which is isolated from one another by their preference for particular marker hosts. That is, host plant is the main pre-zygotic separation mechanism, which is likely to lead the development of post-zygotic separation mechanism and eventually to fully independent species.
