The strawberry (Fragaria) is a genus of plants in the family Rosaceae, and the fruit of these plants.
The strawberry is an accessory fruit; that is, the fleshy part is derived not from the ovaries (which are the "seeds", actually achenes) but from the peg at the bottom of the hypanthium that held the ovaries.
In the rose the extremity of the floral axis is concave and bears the carpels in its interior.
Butterflies and moths feed mostly on nectar, and are not significant pollinators except by accident.
The plantlist with the insect "suspects" you are likely to find on flowers includes most that may be encountered in the Colorado Springs area, maybe also in the Eastern Front Range of the Rockies.
It arrived in the West Indies in 1775, was being planted in greenhouses in England and France early in the 19th Century, and Europeans took it to the East Indies.
The earth around the parent plants is leveled and the process of fertilization, cultivation, ringing and earthing-up and harvesting of stools is repeated over and over for years until the parent plants have lost their vitality.
In the Cook Islands, the trees are planted on a 40 x 20 ft (12 x 6 m) spacing56 trees per acre (134 per ha)but in the 15th year, the plantation is thinned to 40 x 40 ft (12 x l2 m).
The relationships essentially consist in a flux of substances which pass from the non-living components to living ones and in a flux of energy which passes from the photosynthetic organisms (plants) to the herbivorous animals, then to carnivores.
Caterpillars feed only on these plants and it is only on these that the adult female lays her eggs.
According to the technique which is used, the apparatus consists of two small basins which contain an electrolyte, a support (i.e.: filter paper, cellulose acetate strips, polyacrylamide gel, or a capillary tube), an electrical DC power supply and two electrodes.
Because of these traits, multiflora rose was widely planted throughout the eastern United States from the 1930s until the 1960s as living fences, for erosion control, and to protect and feed native wildlife.
By the end of the study (1994), 97% of the marked plants were dead or symptomatic and the density of live multiflora roses had dropped to about 800 per acre, many of which were new, small plants.
The plants first bloomed in 1989 and produced abundant seed in 1990 and 1991 (12 samples; 20 hips each produced an average of 125.3 seed per sample; 90.3% were viable).
Lists a very extensive range of useful plants from around the world with very brief details of the uses.
Poisonous Plants in Britain and their Effects on Animals and Man. HMSO 1984 ISBN 0112425291 Concentrates mainly on the effects of poisonous plants to livestock.
Influence of intercropping on Phyllotreta cruciferae (Coleoptera: Chrysomelidae) populations on collard plants.
It bores in the pith of the soybean stem, girdling it from the inside and sometimes causing the plant to lodge at harvesting.
On soybeans, larvae and adults feed between the veins on the surface of leaves, leaving a lacy network of the tougher leaf tissues.
The caterpillars first feed on tender leaves, gradually move to older leaves, and when foliage is removed, attack tender stems, buds, and small bean pods.
Providing the necessary food plants for the developing caterpillars also allows production of a "native" population that can be observed in all stages of development.
These guides provide general information on the type of habitat each species prefers, what the food plants of the caterpillars are, and when the adults are on the wing, in addition to identification aids.
Most important are: food plants used by the immature stages (various caterpillars), food sources used by the adult butterflies, and physical environment.
