THE EFFECTS OF THE ALKALOID SCOPOLAMINE ON THE PERFORMANCE AND BEHAVIOR OF TWO CATERPILLAR SPECIES.

Arthropod Plant Interact 2018 Feb 5;12(1):21-29. Epub 2017 Jul 5.

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 (Solanaceae) and has been thought to reduce performance and fitness in insects. We examined the effects of the tropane alkaloid scopolamine, the alkaloid constituent of , which is the most frequent host plant for the abundant and widespread insect herbivore in the southwestern United States.

Florivory and nectar-robbing perforations in flowers of pointleaf manzanita (Ericaceae) and their effects on plant reproductive success.

Arthropod Plant Interact 2015 Dec 8;9(6):613-622. Epub 2015 Oct 8.

Division of Open Areas and Biodiversity, Israeli Ministry of Environmental Protection, Jerusalem, Israel.

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 perforations, or extending to the reproductive parts of the flower, as in the case of florivory holes, might determine the extent of the effect on the plant's reproduction.

Floral visual signal increases reproductive success in a sexually deceptive orchid.

Arthropod Plant Interact 2012 Dec;6(4):671-681

Department of Evolutionary Biology, University of Vienna, Althanstra├če 14, 1090 Vienna, Austria.

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. In close vicinity of the flower, visual signals may enhance attraction, as was shown recently in the sexually deceptive orchid . Read More

Visual discrimination between two sexually deceptive Ophrys species by a bee pollinator.

Arthropod Plant Interact 2010 Sep;4(3):141-148

Department of Evolutionary Biology, Faculty of Life Sciences, University of Vienna, Althanstra├če 14, 1090 Vienna, Austria,

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 achromatic flowers, but some exhibit a coloured perianth and a bright, conspicuous labellum pattern. Read More

Mechanical damage to pollen aids nutrient acquisition in butterflies (Nymphalidae).

Arthropod Plant Interact 2009 Dec;3(4):203-208

Brackenridge Field Laboratory and Section of Integrative Biology, University of Texas, Austin, TX 78712, USA.

Neotropical and 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 ( = 72) were collected from proboscides of various species and in surrounding habitats of the Tropical Research Station La Gamba (Costa Rica). Read More

The effect of varying alkaloid concentrations on the feeding behavior of gypsy moth larvae, Lymantria dispar (L.) (Lepidoptera: Lymantriidae).

Arthropod Plant Interact 2008 Jun;2(2):101-107

Towson University, Department of Biological Sciences, 8000 York Road, Towson, MD 21252.

Nine alkaloids (acridine, aristolochic acid, atropine, berberine, caffeine, nicotine, scopolamine, sparteine, and strychnine) were evaluated as feeding deterrents for gypsy moth larvae (Lymantria dispar (L.); Lepidoptera: Lymantriidae). Our aim was to determine and compare the taste threshold concentrations, as well as the ED(50) values, of the nine alkaloids to determine their potency as feeding deterrents. Read More
