“…The evidence types were generally strong, for example 'observations of pollination' (Keighery 1996), moths collecting pollen and depositing it upon pistillate flowers (van Welzen et al 2015), and field observations, pollen on moth bodies, scales on stigmas and experimentation (Rodger et al 2010). The plant families mentioned were Liliaceae, Phyllanthaceae and Epacridaceae.…”

Abstract:On a global-scale, moths (Lepidoptera) are considered to be important pollinators for many plant families. However, the assumption that moths are also involved in pollination in New Zealand is underpinned by relatively little research. Here we review the evidence for moth pollination of flowering plants in New Zealand and compare the quality of evidence available with that of the global literature. Globally, the majority of experimental studies have focused on the hawkmoths (Sphingidae) and other specialist pollinators, leaving a substantial gap in knowledge concerning the role of smaller and more generalist moths as pollinators. New Zealand lacks native Sphingidae; however, members of Geometridae, Noctuidae and Erebidae, all identified as pollinators globally, are mentioned as flower-visitors in New Zealand more than expected given their family sizes. In addition to these families, Oecophoridae are mentioned as flower-visitors in New Zealand but this has not been documented globally, suggesting new mutualisms may have evolved in New Zealand. Eight plant families: Alseuosmiaceae, Argophyllaceae, Campanulaceae, Gentianaceae, Goodeniaceae, Montiaceae, Pittosporaceae and Stylidiaceae, were mentioned in the context of moth pollination in New Zealand, but not in the global literature. The Orchidaceae family is most frequently mentioned in the context of moth pollination globally, but was not mentioned at all in the New Zealand literature, despite two endemic genera, Winika and Earina, showing floral features suggestive of moth pollination. The evidence to support pollination by moths in New Zealand comes predominantly from observations of flower-visitation and assumptions based on floral features. As this is not proof of effective pollen transfer, detailed experimental studies are required before the importance of moths as pollinators in New Zealand can be accurately gauged.Tuhika Whakarāpopoto: Ki te ao whānui, he whakaaiai whakahirahira kā pepe (Lepidoptera) ki kā tipu whaipua.

“…It is widely recognized that the lack of specialization regarding pollinator-plant relationship in common weeds is due to their persistence in time and space (Rodger et al 2010). The evolutionary trend from generalization to specialization noted in natural ecosystems (Johnson and Steiner 2000) probably does not match the requirements of weeds that grow in arable lands.…”

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 floral diversity in agricultural landscapes. Weeds provide food for insects in exchange for pollination. The stability of mutualistic interactions in pollination networks depends on conservation of insect pollinator and weed communities. Some agricultural practices can destabilize interactions and thus modify the stability of pollination networks. Therefore, more knowledge on weed-insect networks is needed. Here, we review the interactions involved in insect visits to weed flowers in temperate arable lands. Our main findings are that (1) weed pollination by insects has a key role in maintaining weed communities in arable lands; (2) weed-insect pollinator interactions are modulated by the flowers' features and their quality which are attracting insects; (3) most weeds are associated with generalist insect pollinators; and (4) even if weed-pollinator networks are largely mutualistic, some antagonist networks can be observed when deception occurs. We propose three weed-insect pollinator networks as potential bio-indicators to evaluate the ecological sustainability of arable land management strategies in temperate areas: (1) Geometridae and Bombyliidae species visiting Caryophyllaceae, (2) Papilionidae foraging on Apiaceae, and (3) Syrphidae visiting Asteraceae.

“…Even in the presence of suitable mates and pollinators, autonomous selffertilization might increase seed production (e.g. Rodger et al 2010), and therefore, result in higher propagule pressure and invasiveness (e.g., Lockwood et al 2005;Colautti et al 2006).…”

A test of baker’s law: breeding systems of invasive species of Asteraceae in China

Invasive alien plant species are frequently characterized by a high fecundity. However, because suitable pollinators and/or mates may be absent in the new range, it is not clear how they achieve high seed production. According to Baker's Law, species capable of uniparental reproduction are more likely to establish after long-distance dispersal than species that rely on suitable mates and pollinators. To test whether selfcompatible species, and particularly species capable of autonomous seed set, are more likely to establish and spread, we experimentally assessed the breeding systems of 12 species of Asteraceae that are invasive in China. Among these 12 species of Asteraceae, the percentages of self-compatible species (66.7%) and species capable of autonomous seed set (83.3%), which included self-fertilizing and apomictic species, were significantly larger than expected from the percentages of such species in global data sets of Asteraceae (36.8% and 46.0%, respectively). Furthermore, the number of Chinese provinces in which the invasive alien species occur was significantly positively correlated with the proportion seed set on bagged capitula (i.e. with the degree of autonomous seed set). Among 36 species of Asteraceae that are invasive in China and for which we found breeding-system data in the literature, we also found a higher than expected percentage of selfcompatible species (65.7%), and that these self-compatible species are more widespread in China than self-incompatible species. These results support the predictions of Baker's Law that self-compatible species, and particularly those capable of autonomous seed production, are more likely to establish and spread in a new range. Therefore, breeding systems of plants should be included as one of the key elements in risk assessment protocols for plant invasiveness.
