Any process that stops, prevents or reduces the rate, frequency or extent of the viral life cycle, the set of processes by which a virus reproduces and spreads among hosts.

The process of expanding or inflating the folded pupal wing, and the adhering of the dorsal and ventral surfaces, to form the mature adult wing.

Those processes pertinent to the generation and maintenance of rhythms in the physiology of an organism.

The specific actions or reactions of an organism that recur with a regularity of approximately 24 hours.

Development of a tissue or tissues that work together to perform a specific function or functions. Development pertains to the process whose specific outcome is the progression of a structure over time, from its formation to the mature structure. Organs are commonly observed as visibly distinct structures, but may also exist as loosely associated clusters of cells that work together to perform a specific function or functions.

The process by which the anatomical structures of blood vessels are generated and organized. Morphogenesis pertains to the creation of form. The blood vessel is the vasculature carrying blood.

The process whereby a relatively unspecialized cell acquires the specialized features of a spermatid cell.

positive regulation of biological process

Any process that activates or increases the rate, frequency or extent of a biological process. Biological processes are regulated by many means; examples include the control of gene expression, protein modification or interaction with a protein or substrate molecule.

negative regulation of biological process

Any process that stops, prevents or reduces the rate, frequency or extent of a biological process. Biological processes are regulated by many means; examples include the control of gene expression, protein modification or interaction with a protein or substrate molecule.

lymph gland development (sensu Arthropoda)

The process whose specific outcome is the progression of the lymph gland over time, from its formation to the mature structure. The lymph gland is one of the sites of hemocyte differentation. It consists of three to six bilaterally paired lobes that are attached to the cardioblasts during larval stages, and it degenerates during pupal stages. As in, but not restricted to, arthropods (Arthropoda, ncbi_taxonomy_id:6656).
