Anthonomus pomorum or the apple blossom weevil is a univoltine herbivore of apple trees, Malus domestica . [1]
Adults generally overwinter in leaf litter of forests or hedgerows. In the spring, they emigrate to orchards and colonize apple trees. [2] [3] They may find their host trees using pheromones or plant-derived chemical cues. [4]
Spiders can be effective predators of A. pomorum. [5]
The peach is a deciduous tree first domesticated and cultivated in Zhejiang province of Eastern China. It bears edible juicy fruits with various characteristics, most called peaches and others, nectarines.
An orchard is an intentional plantation of trees or shrubs that is maintained for food production. Orchards comprise fruit- or nut-producing trees that are generally grown for commercial production. Orchards are also sometimes a feature of large gardens, where they serve an aesthetic as well as a productive purpose. A fruit garden is generally synonymous with an orchard, although it is set on a smaller, non-commercial scale and may emphasize berry shrubs in preference to fruit trees. Most temperate-zone orchards are laid out in a regular grid, with a grazed or mown grass or bare soil base that makes maintenance and fruit gathering easy.
Fire blight, also written fireblight, is a contagious disease affecting apples, pears, and some other members of the family Rosaceae. It is a serious concern to apple and pear producers. Under optimal conditions, it can destroy an entire orchard in a single growing season.
Malus is a genus of about 30–55 species of small deciduous trees or shrubs in the family Rosaceae, including the domesticated orchard apple, crab apples and wild apples.
Pollination of fruit trees is required to produce seeds with surrounding fruit. It is the process of moving pollen from the anther to the stigma, either in the same flower or in another flower. Some tree species, including many fruit trees, do not produce fruit from self-pollination, so pollinizer trees are planted in orchards.
Cider apples are a group of apple cultivars grown for their use in the production of cider. Cider apples are distinguished from "cookers" and "eaters", or dessert apples, by their bitterness or dryness of flavour, qualities which make the fruit unpalatable but can be useful in cidermaking. Some apples are considered to occupy more than one category.
Apple scab is a common disease of plants in the rose family (Rosaceae) that is caused by the ascomycete fungus Venturia inaequalis. While this disease affects several plant genera, including Sorbus, Cotoneaster, and Pyrus, it is most commonly associated with the infection of Malus trees, including species of flowering crabapple, as well as cultivated apple. The first symptoms of this disease are found in the foliage, blossoms, and developing fruits of affected trees, which develop dark, irregularly-shaped lesions upon infection. Although apple scab rarely kills its host, infection typically leads to fruit deformation and premature leaf and fruit drop, which enhance the susceptibility of the host plant to abiotic stress and secondary infection. The reduction of fruit quality and yield may result in crop losses of up to 70%, posing a significant threat to the profitability of apple producers. To reduce scab-related yield losses, growers often combine preventive practices, including sanitation and resistance breeding, with reactive measures, such as targeted fungicide or biocontrol treatments, to prevent the incidence and spread of apple scab in their crops.
Anthonomus is a genus of weevils. This genus includes major agricultural pests such as the boll weevil, strawberry blossom weevil, and pepper weevil, as well as promising biological pest control agents such as Anthonomus santacruzi.
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.
Honeycrisp is an apple cultivar developed at the Minnesota Agricultural Experiment Station's Horticultural Research Center at the University of Minnesota, Twin Cities. Designated in 1974 with the MN 1711 test designation, patented in 1988, and released in 1991, the Honeycrisp, once slated to be discarded, has rapidly become a prized commercial commodity, as its sweetness, firmness, and tartness make it an ideal apple for eating raw. "...The apple wasn't bred to grow, store or ship well. It was bred for taste: crisp, with balanced sweetness and acidity." It has larger cells than most apple cultivars, a trait which is correlated with juiciness, as theoretically a higher number of cells rupture when bitten, releasing more juice in the mouth. The Honeycrisp also retains its pigment well and has a relatively long shelf life when stored in cool, dry conditions. Pepin Heights Orchards delivered the first Honeycrisp apples to grocery stores in 1997. The name Honeycrisp was trademarked by the University of Minnesota, but university officials were unsure of its protection status in 2007. It is now the official state fruit of Minnesota. A large-sized honeycrisp will contain about 113 calories.
The brown planthopper (BPH), Nilaparvata lugens (Stål) is a planthopper species that feeds on rice plants. These insects are among the most important pests of rice, which is the major staple crop for about half the world's population. They damage rice directly through feeding and also by transmitting two viruses, rice ragged stunt virus and rice grassy stunt virus. Up to 60% yield loss is common in susceptible rice cultivars attacked by the insect. The BPH is distributed throughout Australia, Bangladesh, Bhutan, Burma (Myanmar), Cambodia, China, Fiji, India, Indonesia, Japan, North and South Korea, Laos, Malaysia, India, Nepal, Pakistan, Papua New Guinea, Philippines, Sri Lanka, Taiwan, Thailand, and Vietnam. Their alternative host plant other than rice is Leersia hexandra.
Hylobius abietis or the large pine weevil is a beetle belonging to family Curculionidae. This species is widely regarded as the most important pest of most commercially important coniferous trees in European plantations. Seedlings planted or arising from natural regeneration after clear felling operations are especially at risk. The adult weevils cause damage by eating the bark of seedlings around the 'collar' of the stem, thus 'ring-barking' the tree seedling which usually results in its demise.
Gymnosporangium juniperi-virginianae is a plant pathogen that causes cedar-apple rust. In virtually any location where apples or crabapples (Malus) and Eastern red cedar coexist, cedar apple rust can be a destructive or disfiguring disease on both the apples and cedars. Apples, crabapples, and eastern red cedar are the most common hosts for this disease. Similar diseases can be found on Quince and hawthorn and many species of juniper can substitute for the eastern red cedars.
Bechstein's bat is a species of vesper bat found in Europe and western Asia, living in extensive areas of woodland.
Synanthedon myopaeformis is a moth of the family Sesiidae and the order Lepidoptera. In Europe it is known as the red-belted clearwing and in North America as the apple clearwing moth. The larvae create galleries under the bark of fruit trees, especially old trees with damaged trunks. During this process, the larvae cause significant damage to host trees. Particular attention has been paid to the damage they cause to apple trees. Their status as a pest of apple orchards has led to many research projects aimed at controlling populations of the moth. This moth is native to Europe, the Near East and North Africa. Recently, the moth was introduced into North America, being first detected in Canada in 2005. There are several organisms that threaten the larvae, including parasitoids, nematodes, and bacteria.
Gryllus pennsylvanicus is known as the fall field cricket. G. pennsylvanicus is common in southern Ontario, is widespread across much of North America and can be found even into parts of northern Mexico. It tends to be absent in most of the southwestern United States including southern California. Within its geographic range this field cricket will burrow into soil in fields and forest edges. Individuals inhabit grassy disturbed areas and are often found around areas of human habitation.

Perillene is a natural monoterpene that consists of a furan ring with a six-carbon homoprenyl side chain. Perillene is a component of the essential oil obtained by extraction of the leaves of Perilla frutescens. Perillene has also been obtained by steam distillation of the leaves of Perilla frutescens. Perillene has been found to elicit distinct electrophysiological responses in the antennae of the apple blossom weevil. It has been suggested that perillene is one several terpene hydrocarbons in the emanation bouquet of apple tree buds which may be used by adult weevils as chemical cues to discrimination during host-searching behavior.
Curculio elephas is a species of beetle in the family Curculionidae, the true weevils. It is known commonly as the chestnut weevil. It is a serious pest of chestnut in Europe.
Bruchus pisorum, known generally as pea weevil, is a species of leaf beetle in the family Chrysomelidae. Other common names include the pea beetle and pea seed beetle. It is found in Europe and Northern Asia, North America, and temperate Asia.
