The family of Chironomidae is a group of Diptera insects belonging to the suborder of Nematocera, commonly called “non-biting midges” in the adult stage and “bloodworms” in the larval stage. The Chironomidae are often the most abundant group of macroinvertebrates, in number of species and individuals, encountered in all aquatic environments of freshwater, brackish, terrestrial and even the sea. Likewise, Chironomidae occur in all the continents. The Chironomidae family is divided into 11 sub-families that have diffrent ecological statues. Despite the wealth of data on Chironomidae in the Holarctic region, other parts of the world are poorly studied and few guides to identifying Chironomidae have been produced. This chapter includes a theoretical synthesis on the Chironomidae, it deals with the Biology (life cycle and description of different stages), description of all subfamilies and the ecology of this important family of Diptera.

Abstract. Study on the biology of groundnut bruchid, Caryedon serratus Olivier was carried out in the Laboratory of the Department of Agricultural Technology, Adamawa State College of Agriculture, Ganye, Adamawa State from June to September, 2015. The sex of the bruchid (male and female) was assigned the sub-treatment while the period of development was the main treatment and was replicated three times. The work considered the pre-oviposition stage, incubation stage, larval stage, pupal stage, adult stage and the total life cycle of the bruchid (male and female). The experiment was carried out under Laboratory conditions at 30-35°C temperature and 70-90% relative humidity. After the experiment was established, weekly counting of the total number of eggs laid was carried out at intervals. The results showed that, the mean developmental stages in both female and male bruchids were: 6.50 and 6.00 days; 17.00 and 18.00 days; 13.50 and 13.50 days; 12.00 and 13.50 days; 48.00 and 50.00 days for incubation stage, larval stage, pupal stage, adult stage and total life cycle of the bruchids, respectively. Moreover, the mean pre-oviposition and oviposition stages in female adult bruchid were 1.50 and 5.50 days, respectively.

The European wool carder bee Anthidium manicatum (Linnaeus) is a solitary, cavity-nesting bee species in the family Megachilidae (tribe Anthidiini), a family whose members include the mason and leaf cutter bees. Wool carder bees are so named because the female bee scrapes and collects the soft downy hairs (trichomes) of fuzzy plants to use in building a nest for her young. Some consider male wool carder bees very charismatic and enjoy watching them chase after other bees that invade their territory, while others would call them bullies based on male bees’ aggressive tendencies toward other bees when defending floral resources. This species has been called the most widely distributed unmanaged bee in the world (Strange et al. 2011) because of its expansive native and non-native range. This document describes its synonymy, distribution, description, life cycle and biology, hosts, economic importance, and includes selected references.Available on EDIS at https://edis.ifas.ufl.edu/in1274 Also available on the Featured Creatures website at http://entnemdept.ufl.edu/creatures/MISC/BEES/Anthidium_manicatum.html

KNOWING MACROALGAE Turbinaria AND THEIR USAGES. Turbinaria is a member of brown macroalgae that can be found in almost all Indonesian waters. Turbinaria is often regarded as Sargassum because they have a similar morphology and both belong to the Family Sargassaceae. There are 35 species of Turbinaria in the world and 11 of which can be found in Indonesia. Turbinaria conoides, T. decurrens and T. ornata are the most common ones in Indonesian waters. Turbinaria grows on rocky intertidal coastlines, tidepools and reef flats. The life cycle of Turbinaria occurs through alternations between sexual and asexual. Their biphasic life cycle contains gametophytes and sprorophytes. In their sexual reproduction, sporophytes resulted from the germination of zygotes formed by fusion (fertilization) of male and female gametes. Asexual spores develop from both sporophytes and gametophytes. Turbinaria was commonly used as a source of alginate, fucoidan and other bioactive polysaccharides (antioxidant, anticancer, antibacterial, anticoagulant, antiploriferative and antivirus activities).

The obligation of Muslim towards their relatives who died there are four cases, namely bathing, believing, praying and burying. The community considers that there is no need to think about how to care for the body from the beginning to the finish because there are already their own officers. Rhile in a hadist from ‘Aisyah said Rasullah SAW: “Anyone who bathes a corpse and is guarded by trust and cannot be opened (secret) about the protection of the sympathy for the people there hen comes from sin for hs condition. Based on the hadist mentioned the person who mentioned bathe the corpse in priority is his own closest family, then if the family cannot, then other people can do it, while bathing is included in the case of receiving a corpse based on the results of an interview with teacher Madrasah Diniyah Baitul Athfal by agreeing to him about the management of the body, it is expected if it involves family members. Who can use the world od the sunna of the prophet and also in the future can be used as a successor. In Madrasah Diniyah Baitul Athfal involved in the learning process due to shortages in madrasah are short plus students do not have books about the management of bodies or jurisprudence books become obstacles in the process of learning. Teaching lessons for students or instructors. After obtaining data from data collection, .researchers create a system with predetermined and more relevant methods using the Multimedia Development Life Cycle (MDLC) Method. Based on the results obtained for 9352 and included in the category of Good, then the application was validated that can be applied to the research object.

Beetles are a group of insects that form the order Coleoptera, in the superorder Endopterygota. It is estimated that a quarter of all described species in the world belongs to this order. The family Elateridae or click beetles is the ninth-largest family under this order. Wireworms are the larval stage of this family and they play a role in the ecosystem as they are omnivorous and act as pests. There are over 800 species of elaterids recorded from the Indian Subcontinent under eight subfamilies. India is rich in floral and faunal diversity and insect diversity in particular constitute about 6% of all identified insects in the world with a large number being endemic species. But in contrast to its extreme species richness, there is comparatively very little knowledge about this family of beetles when compared to other families. And as such, there is still a lot of potential to study its ecology and diversity. It is also because of this same reason that review of the status of the elaterid family is being done as a prequel to the actual field study.

A list of all valid 6,206 extant and 296 fossil species of Ceratopogonidae described worldwide is provided, along with all their synonyms. A full citation and the country of origin of the type is given, with some larger countries also providing a more specific state or province. For the first time, worldwide, nomina dubia are identified. Numbers of species of each genus and subgenus are listed. Within subfamilies and tribes, genera are listed alphabetically. Five species have newly recognized authors, four have new names and 28 new combinations are recognized, with these listed in a table. A commentary on the state of the systematics in the family and particularly of Culicoides Latreille is given. The museums of the world are listed with the types of various authors of Ceratopogonidae species indicated. Authors providing regional catalogs, as well as summation of various collections are tabulated. The rate of description since 1758 indicates a steady progression of description, with, for example, 1,231 valid species described since the compilation of the world species by Borkent & Wirth (1997), till the end of 2018. The diversity in each Region is compared and the numbers of species shared between adjacent Regions presented.

The tobacco hornworm, Manduca sexta (L.), is a common pest of plants in the family Solanaceae, which includes tobacco, tomato, pepper, eggplant, and various ornamentals and weeds (del Campo and Renwick 1999). Caterpillars in the family Sphingidae are known as hornworms, due to their worm-like body shape and the presence of a small, pointed “horn” at their posterior (Figure 1). The adult stage of Manduca sexta is a heavy-bodied moth that resembles a hummingbird, and Manduca adults are commonly referred to as hawkmoths or hummingbird moths (Figure 2). The larval stage (hornworm) of this species is more often encountered, as it is resides on the host plant during the day and can cause significant defoliation of economically important crops. [...]

The genus of Chrysobothris Eschscholtz, 1829 is one of the most diverse and widespread genera of the family Buprestidae of some 700 described species distributed throughout the world. In Iraq, particularly in the Kurdistan region, about 4 species had been recorded so far, many of these species are sympatric, share larval host plants, and are difficult to reliably separate morphologically. The current study investigates species limits and relationships among the recognized species occurring within the Erbil Province; mitochondrial cytochrome C oxidase (COX I) molecular analysis confirmed the monophyly of two Chrysobothris species, Ch. affinis (Fabricius, 1794) and Ch. chrysostigma (Linnaeus, 1758). Implications of the resultant larval morphology and molecular techniques are discussed. Diagnostic characteristics that are depended to identifying the species within Chrysobothris in larval stage were illustrated and then compared with the molecular data.
