What is the actual laying of the egg called?
The act of depositing or laying eggs is called Oviposition.
What is the medical term meaning delivery of a developed fetus?
Parturition is the term meaning delivery of a developed fetus. A related term, oviposition, means delivery of an egg containing an embryo.

What is the normal body temperature of a hen?
Your Answer is here... Deep-body temperature of the laying hen was measured with an implantable radio transmitter. Food and water intake and oviposition time were recorded, remotely, based on electric signals from microswitches attached to the individual cages. Body temperature and feeding activity of the laying hen under continuous light displayed a circadian rhythm. The length of the body-temperature cycle was 25.2 h, and the feeding cycle was 25.3 h. These values appear to be associated with the animal's laying cycle which was 25.3 h. The laying cycle of the hen can play an important role in the maintenance of circadian rhythms of body temperature and feeding activity. Both the marked temperature rise found at the time of oviposition and the prelaying (or nesting) behavior may be controlled by a preovulatory surge of luteinizing hormone (LH) and progesterone.

Distinguish life - history pattern - age structure?
Age structure is categorization of the population of communities or countries by age groups, allowing demographers to make projections of the growth or decline of the particular population. Life History Patterns • Definitions - Life cycle: morphological and physiological stages through which an organism passes during its lifetime • General stages: egg, juvenile, adult • Generation = time to complete go from egg → juvenile → adult → egg - Life history: various aspects of the life cycle such as rates of growth & development, no. of eggs laid, schedule of oviposition, survivorship patterns, etc.,
What is the 2 stage of a stick insects life cycle?
Stick insects (Phasmatodea) undergo what is called incomplete metamorphosis. This means that their life cycle actually includes three major stages: egg, nymph, and adult. The life cycle begins when the female deposits eggs through oviposition. The eggs hatch after 13-70 days. The young stick insect nymphsresemble adults but must go through several "instars," as they shed old exoskeletons and grow new ones. Once this process of shedding is finished, the nymphs have reached the adult stage, usually after several months and multiple molts.
How can the hatchability of the eggs be influenced by the breeding hen?
many factors fron de hen impact on the hatchability of the eggs, because the hatchability is compound by fertility and embryo`s viability 1.- the age of the hen (old chicken= shell thin / young= shell The opposite) 2.- The size AND WEIGTH of the eggs (Also related to the age) impact on the Conductivity (CO2, H2O and O2 ) BEHAVIOR OF THE EGG IN THE HATCHERY MACHINE. 3.- Nutritional level of the hen [feeding INXS= over weigth= EODES (ERRATIC OVIPOSITION AND DEFECTIVE EGGS SYNDROME= DOUBLE YOLK] ETC ETC

What household products protect against white grubs?
Damage destroy ill important step, also is the best way to prevent myiasis.Improve the health of the environment, destroy reduce maggot breeding grounds, good handling, storage stool, garbage, for special industries such as meat, aquatic products, food processing plants, leather pig field should pay more attention to health management.Destroy maggot breeding environment, isolated breeding materials so that the fly cannot contact oviposition, set screens, screen door, mantle to prevent flies in contact with food, drugs and spraying is effective control measures.Human and animal got myiasis is not terrible, the doctor will take the net, soon recovered after treatment.The animal had a myiasis, in his wounds and ulcers will fly maggot to completely remove the corruption, organized debridement, disinfection of the wound, and then flies to prevent contact, the wound will soon heal
How do you control the boll weevil?
Boll weevils are now considered (eradicated) in most of Georgia. Traditional boll weevil controls included diapause control (sprays and stalk destruction immediately after harvest to prevent weevils from entering diapause), insecticide application at pin-head square stage (to reduce populations of overwintered weevils prior to oviposition), and four to five mid and late season insecticide applications at 3 to 5 day intervals, beginning as early as the first bloom.
