Pears are fruits produced and consumed around the world, growing on a tree and harvested in late summer into mid-autumn. The pear tree and shrub are a species of genus Pyrus, in the family Rosaceae, bearing the pomaceous fruit of the same name. Several species of pears are valued for their edible fruit and juices, while others are cultivated as trees.
Lynx spider (Oxyopidae) is a family of araneomorph spiders first described by Tamerlan Thorell in 1870. Most species make little use of webs, instead spending their lives as hunting spiders on plants. Many species frequent flowers in particular, ambushing pollinators, much as crab spiders do. They tend to tolerate members of their own species more than most spiders do, and at least one species has been identified as exhibiting social behaviour.
Forficula auricularia, the common earwig or European earwig, is an omnivorous insect in the family Forficulidae. The European earwig survives in a variety of environments and is a common household insect in North America. The name earwig comes from the appearance of the hindwings, which are unique and distinctive among insects, and resemble a human ear when unfolded; the species name of the common earwig, auricularia, is a specific reference to this feature. They are considered a household pest because of their tendency to invade crevices in homes and consume pantry foods, and may act either as a pest or as a beneficial species depending on the circumstances.
The codling moth is a member of the Lepidopteran family Tortricidae. They are major pests to agricultural crops, mainly fruits such as apples and pears, and a codling moth larva is often called an "apple worm". Because the larvae are not able to feed on leaves, they are highly dependent on fruits as a food source and thus have a significant impact on crops. The caterpillars bore into fruit and stop it from growing, which leads to premature ripening. Various means of control, including chemical, biological, and preventive, have been implemented. This moth has a widespread distribution, being found on six continents. Adaptive behavior such as diapause and multiple generations per breeding season have allowed this moth to persist even during years of bad climatic conditions.
Psylla pyri, commonly known as the pear psylla or pear psyllid, is an insect in the family Psyllidae. Originating in Europe and Asia, it has spread to North America. It is a pest of pear trees, sucking the sap, damaging the foliage, flowers and fruit and diminishing the crop.
Oxyopes cornutus is a species of lynx spider documented first by F. O. Pickard-Cambridge in 1902, and found in Mexico.
Oxyopes lepidus is a species of lynx spider found in India.
Oxyopes salticus is a species of lynx spider, commonly known as the striped lynx spider, first described by Hentz in 1845. Its habitat tends to be grasses and leafy vegetation; grassy, weedy fields, and row crops.
Oxyopes takobius is a species of spiders in the genus Oxyopes of the lynx spider family, Oxyopidae. The species was first described in 1969, and is found from Central Asia to China. Its venom contains a peptide toxin called oxyopinin, which was discovered in 2002.
Oxyopes lineatus is a species of spider in the family Oxyopidae, the so-called lynx spiders.
Oxyopes macilentus, sometimes known as the lean lynx spider, is a species of lynx spiders from East Asia, South Asia, Southeast Asia, and northern Australia. They are active predators, hunting invertebrates among vegetation. They are especially common in grassy areas and rice fields. Their bodies are characteristically long and thin, about four times as long as it is wide. Their body color ranges from pale white to yellow, orange, or green; with a pattern of black, orange, and white longitudinal lines. Females have a maximum body length of 10 mm (0.39 in), while males grow to 9 mm (0.35 in).
Oxyopes heterophthalmus is a lynx spider from the family Oxyopidae, it is the type species of the genus Oxyopes and was described by Pierre André Latreille in 1804, it has a Palearctic distribution.
Deraeocoris brevis is a species of predatory plant bug in the family Miridae. It is native to North America where it feeds on plant pests in apple and pear orchards.
Oxyopes occidens is a species of lynx spider in the family Oxyopidae. It is found in the United States and Mexico.
Oxyopes apollo, the jumping lynx, is a species of lynx spider in the family Oxyopidae. It is found in the United States and Mexico.
Philodromus cespitum is a species of running crab spider in the family Philodromidae. It is found in North America, Europe, North Africa, and parts of the Middle East and Asia. P. cespitum is a foliage-dweller, and is the most abundant species found in European fruit orchards. It acts as a biological control by preying on orchard pests. P. cespitum is a diurnal ambush hunter and preys on aphids, insects, and occasionally competitor spider species. Males court females by tapping on the females’ bodies with their forelegs. They then insert a genital plug into the female during copulation. Unlike in many other spider species, subsequent males can mate with plugged females by removing part of the plug prior to copulation. Males discriminate among females based on virginity and plug size, and can determine these factors using the females’ draglines and plug samples.
Oxyopes tridens is a species of lynx spider in the family Oxyopidae. It is found in the United States and Mexico.
Oxyopes acleistus is a species of lynx spider in the family Oxyopidae. It is found in the United States and Mexico.
Oxyopes aglossus is a species of lynx spider in the family Oxyopidae. It is found in the United States.
