Uncovering different parameters influencing florivory in a specialist herbivore

1. It has become increasingly recognised that several herbivores switch from folivory (leaf‐feeding) to florivory (flower‐feeding) during larval development. Yet, it remains poorly understood which cues influence this behaviour, whether a switch to florivory is consistently shown on different hosts, and to what extent florivory could be hindered by plant traits. 2. Using the sawfly Athalia rosae and two Brassicaceae differing in architecture and surface structure, the cues that influence larval movement to the flowers were investigated. A broad set of behavioural assays was employed and physical and chemical plant traits potentially affecting the larvae were analysed. Furthermore, the consequences of folivory versus florivory on insect performance were studied. 3. The larvae preferred flowers over leaves. Consumption of particular flower parts correlated partly with measured plant traits such as glucosinolate distribution. Visual cues were of higher importance than volatile cues. The initial position of newly hatched larvae on plants influenced the probability of the larvae reaching the flowers during development. Trichomes and surface waxes hindered the larvae from moving upwards to the flowers. Larvae developed slower and gained less body mass when feeding on inflorescences of Brassica nigra than when feeding on leaves, in contrast to the patterns observed before on Sinapis alba, where florivory led to an improved performance. 4. This study demonstrates that florivory depends on various host plant traits. It reveals new insights into different parameters influencing this multifaceted phenomenon and into the expected impact on the ecology and fitness of both the attacking herbivores and the plants.

尖唇叶蜂属系统分类研究(膜翅目:叶蜂科)

尖唇叶蜂属Adamas Malaise是中国新记录属。本文记述1个中国新记录种：宽缘尖唇叶蜂Adamas jakowleffi(Konow,1897)和4个新种：黄尾尖唇叶蜂A.caudatus sp.nov.,平行尖唇叶蜂A.parallelus sp.nov.,徐氏尖唇叶蜂A.xuisp.nov.和吕氏尖唇叶蜂A.lui sp.nov.,给出了详细描述和形态特征图,并编制了分种检索表。详细讨论了尖唇叶蜂属的系统学地位,初步分析了6个已知种之间的关系,认为A.jakowleffi(Konow)和A.ermak Zhelochovtsev,A.caudatus和A.parallelus.A.xui和A.lui分别构成一对姊妹种关系。尖唇叶蜂属上颚不对称,左上颚具1个大型基齿,右上颚单齿,唇基缺口深,侧叶尖,前翅臀室具很短的倾斜横脉,前胸侧板腹侧接触面窄或无,后胸后背板中央甚狭,后足基跗节很短等,表明本属是平背叶蜂亚科成员,系统学地位介于Allantini族和Empriini族之间,并自成一族——尖唇叶蜂族Adamasini。
