Lebia Grandis
''Lebia grandis'' is a ground beetle in the family Carabidae found in North America. It is a specialist predator on the eggs and larvae of Colorado potato beetles, and its larvae are obligate parasitoids of Colorado potato beetle pupae. Description ''Lebia grandis'' is the largest species in its genus found in North America. It is about one centimetre long with a rusty orange head, thorax and legs, a black abdomen and an iridescent blue or purple lustre to the dark coloured elytra. These are wide but rather shorter than the abdomen which protrudes posteriorly. Life cycle left, 150px, 23 of these Colorado beetle eggs may be eaten each day by a single adult ''Lebia grandis''. Adult ''Lebia grandis'' ground beetles overwinter in soil in or near potato fields. In the spring Colorado potato beetles emerge from hibernation. By the time ''Lebia grandis'' beetles emerge a few weeks later, there are eggs and young larvae of their prey for them to eat and suitable pupae will soon be avail ...

Thomas Say
Thomas Say (June 27, 1787 – October 10, 1834) was an American entomologist, conchologist, and Herpetology, herpetologist. His studies of insects and shells, numerous contributions to scientific journals, and scientific expeditions to Florida, Georgia, the Rocky Mountains, Mexico, and elsewhere made him an internationally known naturalist. Say has been called the father of American descriptive entomology and American conchology. He served as librarian for the Academy of Natural Sciences of Philadelphia, curator at the American Philosophical Society (elected in 1817), and professor of natural history at the University of Pennsylvania. Early life and education Born in Philadelphia into a prominent Religious Society of Friends, Quaker family, Thomas Say was the great-grandson of John Bartram, and the great-nephew of William Bartram. His father, Dr. Benjamin Say, was brother-in-law to another Bartram son, Moses Bartram. The Say family had a house, "The Cliffs" at Gray's Ferry Bridge, ...

Metamorphosis
Metamorphosis is a biological process by which an animal physically develops including birth transformation or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation. Some insects, jellyfish, fish, amphibians, mollusks, crustaceans, cnidarians, echinoderms, and tunicates undergo metamorphosis, which is often accompanied by a change of nutrition source or behavior. Animals can be divided into species that undergo complete metamorphosis (" holometaboly"), incomplete metamorphosis (" hemimetaboly"), or no metamorphosis (" ametaboly"). Generally organisms with a larval stage undergo metamorphosis, and during metamorphosis the organism loses larval characteristics. Etymology The word ''metamorphosis'' derives from Ancient Greek , "transformation, transforming", from ('), "after" and ('), "form". Hormonal control In insects, growth and metamorphosis are controlled by hormones synthesized by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insects Used As Insect Pest Control Agents
Insects (from Latin ') are hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes, and a pair of antennae. Insects are the most diverse group of animals, with more than a million described species; they represent more than half of all animal species. The insect nervous system consists of a brain and a ventral nerve cord. Most insects reproduce by laying eggs. Insects breathe air through a system of paired openings along their sides, connected to small tubes that take air directly to the tissues. The blood therefore does not carry oxygen; it is only partly contained in vessels, and some circulates in an open hemocoel. Insect vision is mainly through their compound eyes, with additional small ocelli. Many insects can hear, using tympanal organs, which may be on the legs or other parts of the body. Th ...

Leaf Beetle
The beetle family Chrysomelidae, commonly known as leaf beetles, includes over 37,000 (and probably at least 50,000) species in more than 2,500 genera, making it one of the largest and most commonly encountered of all beetle families. Numerous subfamilies are recognized, but the precise taxonomy and systematics are likely to change with ongoing research. Leaf beetles are partially recognizable by their tarsal formula, which appears to be 4-4-4, but is actually 5-5-5 as the fourth tarsal segment is very small and hidden by the third. As with many taxa, no single character defines Chrysomelidae; instead, the family is delineated by a set of characters. Some lineages are only distinguished with difficulty from longhorn beetles (family Cerambycidae), namely by the antennae not arising from frontal tubercles. Members of former chrysomelid subfamilies ( Orsodacnidae and Megalopodidae) are also difficult to differentiate from true chrysomelids. Adult and larval leaf beetles feed o ...

Physalis
''Physalis'' (, , , , from 'bladder') is a genus of approximately 75 to 90 flowering plants in the Solanum, nightshade family (Solanaceae), which are native to the Americas and Australasia. At least 46 species are endemism, endemic to Mexico. Cultivated and weedy species have been introduced worldwide. A defining feature of ''Physalis'' is a large, papery husk derived from the sepal, calyx, which partly or fully encloses the fruit. Many species bear edible fruit, and some species are cultivated. The typical ''Physalis'' fruit is similar to a firm tomato in texture, and like a sweet, tangy grape in flavor. Some species, such as the Physalis peruviana, Cape gooseberry and tomatillo, have been bred into many cultivars with varying flavors, from tart to sweet to savory. Nations including Colombia, India, and Mexico have a significant economic trade in ''Physalis'' fruit. The fruits of many species are generically referred to as physalis, groundcherries, husk tomatoes, husk cherries ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leptinotarsa Haldemani
''Leptinotarsa haldemani'', commonly known as Haldeman's green potato beetle, is a glossy green-colored species of beetle in the leaf beetle family Chrysomelidae. It was named in honour of Samuel Stehman Haldeman, a 19th-century American entomologist who collected insect specimens in Texas. Description This small beetle has a black head, antennae, thorax, and legs. Its general body shape is domed and the elytra are usually deep metallic green, but sometimes metallic purple or blue. Distribution This species is found in Mexico, Central America, and the US states of Arizona, New Mexico, Oklahoma, and Texas. Host plants This beetle is found on members of the family Solanaceae including wild species of ''Physalis'', ''Solanum douglasii'', and the Anderson thornbush, ''Lycium andersonii ''Lycium andersonii'' is a species of flowering plant in the nightshade family, Solanaceae.

Solanum Carolinense
''Solanum carolinense'', the Carolina horsenettle, is not a true nettle, but a member of the Solanaceae, or nightshade family. It is a perennial herbaceous plant, native to the southeastern United States, though its range has expanded throughout much of temperate North America. The plant is an invasive in parts of Europe, Asia, Africa and Australia. The stem and undersides of larger leaf veins are covered with prickles. "Horsenettle" is also written "horse nettle" or "horse-nettle", though USDA publications usually use the one-word form. Though there are other horsenettle nightshades, ''S. carolinense'' is the species most commonly called ''"the'' horsenettle". Other common names include radical weed, sand brier or briar, bull nettle, tread-softly, Solanum mammosum ("apple of Sodom"), devil's tomato and wild tomato. Description Leaves are alternate, elliptic-oblong to oval, long, and each is irregularly lobed or coarsely toothed. Both surfaces are covered with fine hair ...

Leptinotarsa Juncta
The false potato beetle (''Leptinotarsa juncta'') is a beetle found primarily in the Mid-Atlantic and Southeastern United States. Its distribution extends to Maine. Adult beetles emerge from the soil in the late spring or early summer and begin breeding, and a population may go through one to three generations in a summer. The false potato beetle feeds on solanaceous weeds such as horsenettle, ''Solanum carolinense''. It also feeds on other solanaceous plants, such as species of ground cherry or husk tomato, ''Physalis'' spp., and bittersweet, ''Solanum dulcamara'', but no growth and reproduction occurs when feeding on the potato, ''Solanum tuberosum''. ''L. juncta'' can be easily confused with its congener the Colorado potato beetle The Colorado potato beetle (''Leptinotarsa decemlineata''; also known as the Colorado beetle, the ten-striped spearman, the ten-lined potato beetle, and the potato bug) is a beetle known for being a major pest of potato crops. It is about l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solanum Rostratum
''Solanum rostratum'' is a species of nightshade (genus ''Solanum'') that is native to the United States and northern and central Mexico. Common names include buffalobur nightshade, buffalo-bur, spiny nightshade, Colorado bur, Kansas thistle, bad woman, Mexican thistle, and Texas thistle. It is an annual, self-compatible herb that forms a tumbleweed. Individual plants reach tall, have once or twice pinnatified leaves (see image of leaf), and abundant spines on the stems and leaves. It produces yellow flowers with pentagonal corollas in diameter and weakly bilaterally symmetric (see flower-closeup image). In its native range ''S. rostratum'' is pollinated by medium- to large-sized bees including bumblebees. ''Solanum rostratum'' flowers exhibit heteranthery, i.e. they bear two sets of anthers of unequal size, possibly distinct colouration, and divergence in ecological function between pollination and feeding. The fruit, a berry, is enclosed by a prickly calyx. The seeds are r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coleomegilla Maculata
''Coleomegilla maculata'', commonly known as the spotted lady beetle, pink spotted lady beetle or twelve-spotted lady beetle, is a large coccinellid beetle native to North America. The adults and larvae feed primarily on aphids and the species has been used as a biological control agent. Based on name connotation and to avoid confusion with other species also called "spotted ladybeetle", spotted pink ladybeetle is probably the most appropriate common name for this species. Description This is generally an oblong, flattened lady beetle species averaging about six millimetres long. Over most of its range the species is pink in coloration, except for subspecies ''fuscilabris'' which is bright orange or red. Each elytron features 6 black markings. The thorax is a similar shade of red with two large triangular black patches. Similarity is most apparent with the seaside lady beetle, but that species is limited to coastal habitats and features much larger black markings. In that spe ...
