| After development to a small blastodermic disc, the embryos enter a state of diapause that lasts approximately 7 months. |
|
| The coarctate or pseudopupal stages are those in which hibernation or diapause occurs most frequently. |
|
| By the third week, most females will be laying progeny that will enter diapause. |
|
| Their reproductive cycle is characterized by a period of embryonic diapause, during which the blastocyst suspends implantation and development. |
|
| Eggs hatching from diapause introduce to current environments species or genotypes laid at times in the distant past. |
|
| During winter, the pupae go into diapause or retarded development until the following spring. |
|
| Occassionally, however, spider mites may also enter diapause in February in greenhouses not just for winter. |
|
| Many of the insects that go into diapause are eggs and pupae awaiting the arrival of spring and its bounty of food before hatching into adults, Holscher said. |
|
| Although a state of arrested development may occur during any stage, diapause occurs most commonly in pupae. |
|
| Termination of diapause can be brought about by reversing the environmental conditions that induced the diapause. |
|
| The pupa may undergo a facultative diapause, which considerably extends the pupal period. |
|
| The adults then emerge, and later enter diapause to overwinter in the soil. |
|
| The 17-year larval and pupal periods of the cicada are examples of diapause. |
|
| Two basic types of pupal diapause are recognized, one in relation to cold and the other in response to arid conditions. |
|
| Negligible oviposition occurs before diapause, but diapausing females about 30 days old often become reproductive. |
|
| After emergence, adults enter a diapause, the duration of which varies with the geographic range. |
|
| Under laboratory conditions, 4-5°C was found to be more suitable for diapause than 0°C or lower. |
|
| Fortunately, only very low light intensities are sufficient to prevent diapause. |
|
| In unfavourable conditions, the eggs of some species may remain in diapause in the soil for two or three years. |
|
| The eggs of many species go through a diapause to survive either winter or dry periods. |
|
|
|
| These ridges indicate the period of diapause during the winter or unfavorable environmental conditions, such as lower water level or lack of food. |
|
| Eggs diapause over winter, and development resumes after the spring thaw. |
|
| He also notes that the tropical M. crudus reproduces continually throughout the year, and is limited by its lack of winter diapause to areas with sufficiently mild winters. |
|
| Eggs normally require a cold-induced diapause period before they will hatch, although a proportion of the population may hatch during a warm prolonged autumn. |
|
| Photoperiodic induction of diapause hibernation and voltinism in Piezodorus hybneri. |
|
| The immediate cause of diapause, failure to secrete the growth and molting hormones, usually is induced by a decrease in daylength as summer wanes. |
|
| Most larvae from the spring and summer broods go into diapause in early instars, but some continue to mature to produce another flight of adults about six weeks later. |
|
| Photoperiodic control of diapause and climatic adaptation of the house spider, Achaearanea tepidariorum. |
|
| Some caterpillars will even go into diapause, a resting stage that enables them to await more favourable conditions, and makes them more resistant to fumigation. |
|
| The insect endocrine system produces neurohormones as well as hormones that control molting, diapause, reproduction, osmoregulation, metabolism, and muscle contraction. |
|
| Some insects enter diapause during development. |
|
| Lifehistory traits related to diapause in univoltine and bivoltine populations of Ypthima multistriata inhabiting similar latitudes. |
|
| Little is known about this in Toxorhynchites rutilus septentrionalis, but it seems doubtful that diapause as eggs would be possible. |
|
| This cessation of growth, known as diapause, is a highly effective adaptation that enables the insects to avoid environmental conditions hostile to developing nymphs or to emerging winged stages. |
|
| After only one week's development, the microscopic embryo enters a dormant state, called diapause, that lasts until the first joey begins to leave the pouch or until conditions are otherwise favourable. |
|
| As caterpillars, Glanville fritillaries enter a stage of diapause, which is a period of suspended development, during the winter time. |
|
| A few adults live through two seasons with a diapause period between. |
|
| A large proportion of 2nd generation larvae, born at the end of July to beginning of August, enter diapause when at the black scale stage and overwinter in this form. |
|
| Or does WNV survive the harsh winters inside mosquitoes undergoing diapause, only to reemerge in the spring? |

| Effect of juvenile hormone analogs on diapause termination and myo-inositol content in Aulacophora nigripennis. |

|
| Effect of age, diet, diapause and juvenile hormone on oogenesis and the amount of vitellogenin and vitellin in the twospotted stink bug, Perillus bioculatus. |
