Bombyx Mori

Larval diapause

C vicina


D grandiosella

Pupal diapause

S crassipalpis


M sexta

Adult diapause

D melanogaster


D plexxipus

Long day insects

Noctuid moth c vicina p brassicae

Temperate diapause temperature induce

Some ground beetles


<15°C = development halted


>7°C= development resumes

Tropical diapause temperature induce

Muscoid fly


Larvae reared 20deg = no diapause


Larvae reared 18deg = some diapause


More diapause with decrease temp

Photoperiodic maintenance of diapause

Pitcher plant mosquito


Autumn diapause maintained by critical photoperiod broken when exceeded in spring

Temperature maintenance of diapause

Many spp have longer more intense diapause at lower remps eg s crassipalpis

Modifying diapause response after induction

C vicina


ADULT LD 12:12 and larvae <15°c = diapause


Adult LD 12:12 And larvae >15°c = diapause averted
