Anastatus Disparis
''Anastatus disparis'' is a species of egg parasitoid. Hosts include ''Lymantria dispar'' and ''Antheraea pernyi''. The species is sexually dimorphic, with 630 sex specific genes. Females have 11 antennal subsegments, whereas males have 8. Females only mate once, and males are significantly shorter lived than females, engaging in agonistic behavior Agonistic behaviour is any social behaviour related to fighting. The term has broader meaning than aggressive behaviour because it includes threats, displays, retreats, placation, and conciliation. The term "agonistic behaviour" was first implemen ....

Lymantria Dispar Dispar
''Lymantria dispar dispar'' or LDD moth, commonly known as the gypsy moth, European gypsy moth, North American gypsy moth, or spongy moth, is a species of moth in the family Erebidae that is of Eurasian origin. It has a range that extends over Europe, Africa, and North America. Carl Linnaeus first described the species ''Lymantria dispar'' in 1758. The subject of classification has changed throughout the years, resulting in confusion surrounding the species' taxonomy. This caused many references to describe this one species in different ways. The family has jumped between Lymantriidae, Noctuidae and Erebidae. ''Lymantria dispar dispar'' has been designated a subspecies of ''Lymantria dispar''. It is classified as a pest, and its larvae consume the leaves of over 500 species of trees, shrubs and plants. The gypsy moth is one of the most destructive pests of hardwood trees in the Eastern United States. It is listed as one of the 100 most destructive invasive species worldwide. ...

Antheraea Pernyi
''Antheraea pernyi'', the Chinese (oak) tussar moth, Chinese tasar moth or temperate tussar moth, is a large moth in the family Saturniidae. The species was first described by Félix Édouard Guérin-Méneville in 1855. '' Antheraea roylei'' is an extremely close relative, and the present species might actually have evolved from ancestral ''A. roylei'' by chromosome rearrangement. They are originally from southern China. Used for tussar silk production, they have been distributed more widely across subtropical and tropical Asia. Unlike the domestic silk moth which is entirely dependent on human care, tussah silk moths can survive in the wild if they escape from captivity; small local populations of such feral stock may thus occasionally occur. The colour and quality of the silk depends on the climate and soil. This is one of the major producers of tussar silk. It was of commercial importance during the Han Dynasty and early Three Kingdoms era, about 200 BC to 250 AD. More rece ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexually Dimorphic
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated d ...

Agonistic Behavior
Agonistic behaviour is any social behaviour related to fighting. The term has broader meaning than aggressive behaviour because it includes threats, displays, retreats, placation, and conciliation. The term "agonistic behaviour" was first implemented by J.P Scott and Emil Fredericson in 1951 in their paper "The Causes of Fighting in Mice and Rats" in ''Physiological Zoology.'' Agonistic behaviour is seen in many animal species because resources including food, shelter, and mates are often limited. Some forms of agonistic behaviour are between contestants who are competing for access to the same resources, such as food or mates. Other times, it involves tests of strength or threat display that make animals look large and more physically fit, a display that may allow it to gain the resource before an actual battle takes place. Although agonistic behaviour varies among species, agonistic interaction consists of three kinds of behaviours: threat, aggression, and submission. These thre ...

Eupelmidae
Eupelmidae is a family of parasitic wasps in the superfamily Chalcidoidea. The group is apparently polyphyletic, though the different subfamilies may each be monophyletic, and may be elevated to family status in the near future. As presently defined, there are over 905 described species in 45 genera. The larvae of the majority are primary parasitoids, commonly on beetle larvae, though many other hosts are attacked, including spiders, and details of the life history can be variable (e.g., some attack eggs and others are hyperparasites). They are found throughout the world in virtually all habitats. They are somewhat variable in appearance, though a fair number of species are relatively easy to separate from other Chalcidoidea by the possession of a medially concave mesonotum. They also have the unusual tendency to arch the body strongly upwards when dead, with the head and metasoma often nearly touching above the thorax.
