Few insect species

Insects share similar fundamental molecular principles with mammals in innate immunity. For modulating normal gut microbiota, insects produce phenoloxidase (PO), which is absent in all vertebrates, and reactive nitrogen species (ROS) and antimicrobial proteins (AMPs). However, reports on insect gut phagocytosis are very few. Furthermore, most previous studies measure gene expression at the transcription level. In this study, we provided proteomic evidence on gut modulation of normal microorganisms by investigating the anal droplets from a weevil, Cryptorhynchus lapathi.

The lack of an understanding about the genomic architecture underpinning parental behaviour in subsocial insects displaying simple parental behaviours prevents the development of a full understanding about the evolutionary origin of sociality. Lethrus apterus is one of the few insect species that has biparental care.

Honey is one of the oldest and best loved sweetening agents for foods and over the centuries, it has still retained a “natural image”. The raw materials for the production of „Floral honey‟ are nectar, a dilute solution of sugars found in the nectarines of the flowering plants.

Forensic science is the application of science to criminal and civil laws and the forensic entomology is the science of collecting and analyzing insect evidence to aid in forensic investigations. The review here encompassed the brief details on the criminal and civil issues related information that can be gathered through insects; clues about a crime through insect species succession; insect groups involved in forensic studies; stages of decomposition by insect activity and few case studies.

Antimicrobial peptides form one of the first lines of defense against invading pathogens by killing the microorganisms and/ormobilizing the host innate immune system. Although over 800 antimicrobial peptides have been isolated from many different species, especially insects, few have been reported frommarinefish. Sequenceanalysisof twogenomic clones (15.6 and 12.5 kb) from the winter flounder, Pseudopleuronectes americanus(Walbaum) resulted in the identification of multiple clustered genes for novel pleuro-cidin-like antimicrobial peptides....

A number of biologists have probed the history of insects to determine what factors account for their huge diversity. Peter Mayhew, a biologist at the Univer- sity of York, has tested the leading hypotheses. Insects don’t seem to have a par- ticularly high rate of speciation, he has found, but they do seem good at with- standing extinctions. Fifty percent of all families of insect species alive today existed 250 million years ago. None of the families of tetrapod species alive 250 million years ago exists today; all have been replaced by newer groups.

6 Population Dynamics POPULATIONS OF INSECTS CAN CHANGE DRAMATICALLY IN SIZE OVER relatively short periods of time as a result of changes in natality, mortality, immigration, and emigration. Under favorable environmental conditions, some species have the capacity to increase population size by orders of magnitude in a few years.
