The economic impact of failures in plant protection to New Zealand

Saunders, John; Saunders, Caroline M.; Buwalda, James; Gerard, P. J.; Bourdot, G. W.; Wratten, Stephen D.; Goldson, Stephen (PeerJ Preprints, 2013-12-04)

Plant weeds, pests and diseases comprise significant threats to pastoral agriculture in New Zealand. The extent of damage incurred by New Zealand’s agricultural industry from these weed and pest threats varies significantly ...

Disentangling higher trophic level interactions in the cabbage aphid food web using high-throughput DNA sequencing

Lefort, Marie-Caroline; Wratten, Stephen D.; Cusumano, A.; Varennes, Yann-David; Boyer, Stephane (Pensoft Publishers, 2017-10-18)

The lack of understanding of complex food-web interactions has been a major gap in the history of biological control. In particular, a better understanding of the functioning of pest food-webs and how they vary between ...

Weed-insect pollinator networks as bio-indicators of ecological sustainability in agriculture. A review

Rollin, O.; Benelli, G.; Benvenuti, S.; Decourtye, A.; Wratten, Stephen D.; Canale, A.; Desneux, N. (Springer Paris, 2016-03)

The intensification of agricultural practices contributes to the decline of many taxa such as insects and wild plants. Weeds are serious competitors for crop production and are thus controlled. Nonetheless, weeds enhance ...

Continental-scale suppression of an invasive pest by a host-specific parasitoid underlines both environmental and economic benefits of arthropod biological control

Wyckhuys, K. A. G.; Wongtiem, P.; Rauf, A.; Thancharoen, A.; Heimpel, G. E.; Le, N. T. T.; Fanani, M. Z.; Gurr, G. M.; Lundgren, J. G.; Burra, D. D.; Palao, L. K.; Hyman, G.; Graziosi, I.; Le, V. X.; Cock, M. J. W.; Tscharntke, T.; Wratten, Stephen D.; Nguyen, L. V.; You, M.; Lu, Y.; Ketelaar, J. W.; Goergen, G.; Neuenschwander, P. (PeerJ, 2018-10-19)

Biological control, a globally-important ecosystem service, can provide long-term and broad-scale suppression of invasive pests, weeds and pathogens in natural, urban and agricultural environments. Following (few) historic ...

Scarcity of ecosystem services: an experimental manipulation of declining pollination rates and its economic consequences for agriculture

Sandhu, H. S.; Waterhouse, Benjamin; Boyer, Stephane; Wratten, Stephen D. (PeerJ, 2016-07-05)

Ecosystem services (ES) such as pollination are vital for the continuous supply of food to a growing human population, but the decline in populations of insect pollinators worldwide poses a threat to food and nutritional ...

Host plants affect the foraging success of two parasitoids that attack light brown apple moth Epiphyas postvittana (Walker) (Lepidoptera: Tortricidae)

Feng, Y.; Wratten, Stephen D.; Sandhu, H. S.; Keller, M. (Public Library of Science, 2015-04-20)

The light brown apple moth, Epiphyas postvittana is a key pest of wine grapes in Australia. Two parasitoids, Dolichogenidea tasmanica and Therophilus unimaculatus, attack the larval stage of this pest. D. tasmanica is ...

Enhancing nectar provision in vineyard habitats for the endemic New Zealand butterfly, Lycaena salustius

Gillespie, Mark A.; Wratten, Stephen D. (New Zealand Ecological Society, 2013)

Nectar is an important factor influencing the level and persistence of butterfly populations, but particular sources of nectar may not be optimal for all species. In a farmland context, it is not always clear whether nectar ...

A global synthesis reveals biodiversity-mediated benefits for crop production

Dainese, M.; Martin, E. A.; Aizen, M. A.; Albrecht, M.; Bartomeus, I.; Bommarco, R.; Carvalheiro, L. G.; Chaplin-Kramer, R.; Gagic, V.; Garibaldi, L. A.; Ghazoul, J.; Grab, H.; Jonsson, M.; Karp, D.

K.; Wratten, Stephen D.; Yoshioka, A.; Zaragoza-Trello, C.; Zhang, Wei; Zou, Yi; Steffan-Dewenter, I. (American Association for the Advancement of Science, 2019-10-16)

Human land use threatens global biodiversity and compromises multiple ecosystem functions critical to food production. Whether crop yield-related ecosystem services can be maintained by a few dominant species or rely on ...

Ecological and pest-management implications of sex differences in scarab landing patterns on grape vines
