TL;DR: Although cell death is known as apoptosis ve necrosis, molecular studies add to morphological studies and according to this, this classification is extended and there are diffirent types of cell death in terms of signal pathway.
Abstract: In 1972 Kerr and colleagues collect the cell death under two headings. Although cell death is known as apoptosis ve necrosis, molecular studies add to morphological studies and according to this, this classification is extended. In 2009 NCCD classifies it entosis, mitotic collapse, necrosis, necropitosis and pyroptosis by using terminological words. In addition to these there are diffirent types of cell death in terms of signal pathway. These are autophagic cell death, carnification cell death, netoz cell death, partanatoz cell death, anoikis cell death. In this article these types of cell death is noticed in detail.
TL;DR: Insect’s immune responses as melanization, lysozyme level and phenoloxidase (PO) modify the physiology and morphological behavior against different factors like diets, gases and chemicals, which influence the insects and their population dynamics.
Abstract: Insects are powerful and rapid adaptive organisms with high fecundity rate and short life cycle. Due to human interruption in agro-ecosystem and global climatic variations are disturbing the insect ecosystem. Erosion of natural habitats, urbanization, pollution and use of chemicals in agroecosystem manifold the intensity of environmental variations. Both a-biotic (temperature, humidity, light) and biotic (host, vegetative biodiversity, crowding and diets) stresses significantly influence theinsects and their population dynamics. In response to these factors insect may prolong their metamorphic stages, survival and rate of multiplication. Insect’s immune responses as melanization,lysozyme level and phenoloxidase (PO) modify the physiology and morphological behavior against rndifferent factors like diets, gases and chemicals.
TL;DR: This study showed the possibility of production of insect larvae biomass as through bioconversion process of agricultural waste rich with lignocellulose and lowest waste reduction efficiency was recorded by larvae feed rate.
Abstract: This study focuses on the application of black soldier fly larvae (Hermetia illucens L) as a bioconversion agent of the rice straw to reduce amount of waste while in the same time produced larvae biomass In this study, larvae were fed with rice straw at six different feed rates (125, 25, 50, 100, and 200 mg/larvae/day) until larvae reached prepupal stage During study, relative growth, relative consumption rate, and waste reduction level were measured Daily feeding of 200 mg of grinded rice straw per larvae resulted in the highest prepupal dry weight (1559 ± 001 mg), lowest developmental time (39 ± 01 days), but lowest waste reduction efficiency (1085 ± 00005%) Highest waste reduction efficiency was recorded by larvae feed rate of 125 mg/larvae/day (3153 ± 001%) and decreased with higher feeding rate This study showed the possibility of production of insect larvae biomass as through bioconversion process of agricultural waste rich with lignocellulose
TL;DR: Light is shed on deltamethrin induced various toxicities during acute and chronic exposure in different species.
Abstract: Pyrethroids are synthetic organic compounds synthesized from chrysanthemum flowers that are used extensively as household and commercial insecticides. The keto-alocoholic esters of chrysanthemic and pyrethroic acid being lipophilic are responsible for its insecticidal properties. Pyrethroids are broadly classified into first and second generation pyrethroids. The first generation (Type 1) pyrethroids are less toxic to mammals than the second generation (Type II) pyrethroids. Mainly Type II pyrethroids cause paresthesia, which is characterized by transient burning/tingling/itching sensation of the exposed skin. Also, it has been suggested that some pyrethroids cause developmental neurotoxicity, but available evidence has been judged to be insufficient. While some pyrethroids have been shown to cause tumors in rodent models, the tumor induction does not appear to reflect a common carcinogenic endpoint for this particular subset of compounds. Deltamethrin is an alpha-cyano pyrethroid insecticide used extensively in pest control. Although initially thought to be least toxic, a number of recent reports showed its toxicity in mammalian and non-mammalian laboratory and wildlife animal species. The article sheds light on deltamethrin induced various toxicities during acute and chronic exposure in different species.
TL;DR: In the changing ecological conditions this mosquito might enhance its epidemiological importance in the near future as a smart vector for those pathogens which were isolated from this mosquito species but are presently not having any public health importance.
Abstract: Culex quinquefasciatus is the principal vector of bancroftian filariasis and a potential vector of Dirofilaria immitis. This mosquito species is also a potential vector of several arboviruses like West Nile virus (WNV), Rift Valley fever virus, avian pox and protozoa like Plasmodium relictum that causes bird malaria. This species has the ability to transmit other nematodes like Saurofilaria sp., Oswaldofilaria sp. In the USA, it is a potential vector of St. Louis encephalitis virus (SLEV). Japanese encephalitis virus (JEV) has been isolated from this mosquito in several occasions in Asia. Furthermore, it can transmit several other arboviruses in the laboratory conditions. This article is an attempt to review the bio-ecology, medical and veterinary importance of Culex quinquefasciatus. It acts as an important “urban bridge vector” which bridges different reservoir/amplifier hosts to humans because of its encounter with different vertebrates. Culex quinquefasciatus also creates an ecological bridge between urban, periurban and rural areas owing to its presence and adaptability in diverse ecological niches. Culex quinquefasciatus emerged as a smart vector because of the adaptive fitness, ecological plasticity, invasive behaviour, host specificity and high reproductive potential along with expanded immune gene repertoire property at the genetic level. This mosquito possesses the necessary potential to initiate and facilitate the disease transmission by establishing an effective vector-host transmission cyclernfor diverse pathogens in different environments. Thus, in the changing ecological conditions this mosquito might enhance its epidemiological importance in the near future as a smart vector for those pathogens which were isolated from this mosquito species but are presently not having any public health importance.
