Agricultural intensification is a major threat to farmland biodiversity and associated ecosystem services. Semi-natural habitats are integral to the preservation of farmland biodiversity and ecosystem services, however, the extent in which ...
The Localization of Phytohormones within the Gall-inducing Insect Eurosta solidaginis (Diptera: Tephritidae) [0.03%]
金蝇(Eurosta solidaginis)(双翅目,果蝇科)虫瘿内植物激素的定位分析

Gabriela E Ponce et al.
The phytohormone production hypothesis suggests that organisms, including insects, induce galls by producing and secreting plant growth hormones. Auxins and cytokinins are classes of phytohormones that induce cell growth and cell division, ...
Insect chemical ecology: chemically mediated interactions and novel applications in agriculture [0.03%]
昆虫化学生态学:化学介导的相互作用及其在农业中的新应用

Crispus M Mbaluto et al.
Insect chemical ecology (ICE) evolved as a discipline concerned with plant-insect interactions, and also with a strong focus on intraspecific pheromone-mediated communication. Progress in this field has rendered a more complete picture of h...

Floral guides are signal patterns that lead pollinators to floral rewards after they have located the flower, and increase foraging efficiency and pollen transfer. Patterns of several floral signalling modalities, particularly colour patter...
THE EFFECTS OF THE ALKALOID SCOPOLAMINE ON THE PERFORMANCE AND BEHAVIOR OF TWO CATERPILLAR SPECIES [0.03%]

Plants have evolved many defenses against insect herbivores, including numerous chemicals that can reduce herbivore growth, performance, and fitness. One group of chemicals, the tropane alkaloids, is commonly found in the nightshade family ...
Florivory and nectar-robbing perforations in flowers of pointleaf manzanita Arctostaphylos pungens (Ericaceae) and their effects on plant reproductive success [0.03%]
花客侵和盗蜜行为对尖叶火刺 Pearman 火刺曼扎娜(越橘科)植物繁殖成功的影响

Dorit Eliyahu et al.
Damage to petals may have varying effects on the reproductive success of the plant. The variation may depend on the kind of damage to the corolla. Whether the damage is limited to the corolla, as is usually the case with nectar-robbing perf...
Mechanical damage to pollen aids nutrient acquisition in Heliconius butterflies (Nymphalidae) [0.03%]
机械损伤的花粉有利于Heliconius凤蝶获取营养素
Harald W Krenn,Monika J B Eberhard,Stefan H Eberhard et al.
Harald W Krenn et al.
Neotropical Heliconius and Laparus butterflies actively collect pollen onto the proboscis and extract nutrients from it. This study investigates the impact of the processing behaviour on the condition of the pollen grains. Pollen samples (n...
Floral visual signal increases reproductive success in a sexually deceptive orchid [0.03%]
花朵视觉信号提高了欺骗性兰花的繁殖成功率
Demetra Rakosy,Martin Streinzer,Hannes F Paulus et al.
Demetra Rakosy et al.
Sexually deceptive orchids mimic signals emitted by female insects in order to attract mate-searching males. Specific attraction of the targeted pollinator is achieved by sex pheromone mimicry, which constitutes the major attraction channel...
Visual discrimination between two sexually deceptive Ophrys species by a bee pollinator [0.03%]
两种性诱兰花间的视觉分辨度及其传粉者的反应
M Streinzer,T Ellis,H F Paulus et al.
M Streinzer et al.
Almost all species of the orchid genus Ophrys are pollinated by sexual deception. The orchids mimic the sex pheromone of receptive female insects, mainly hymenopterans, in order to attract males seeking to copulate. Most Ophrys species have...
