Control of cell proliferation in the corpora allata during the reproductive cycle of the cockroach Diploptera punctata [PDF]

open access: yes, 2010
[[abstract]]Unlike in Blettella germanica and Supella longipalpa, the corpora allata (CA) of Diploptera punctata exhibited cyclic changes in cell number during the reproductive cycle. In mated females, a wave of DNA synthesis followed by mitosis resulted

Protein Profiles of Larval Haemolymph of Bombyx mori in Artificially Induced Trimolting larvae using a 1,5-disubstituted Imidazole [PDF]

open access: yes, 1997
Trimolter larvae (undergoing three larval molts) of Bombyx rnori were induced artificially by administrating I-benzyl-5-[ (E)-2,6)-dimethyl-l ,5-heptadienyl]-imidazole (an insect growth regulator called KK-42) shortly after the third molt, and analyzed ...

The nature and development of sex attractant specificity in cockroaches of the genus Periplaneta . II. Juvenile hormone regulates sexual dimorphism in the distribution of antennal olfactory receptors [PDF]

open access: yes, 1976
Sexual dimorphism of antennal sense organs appears only at the adult stage during normal development of the cockroach, Periplaneta americana. Adult males acquire approximately twice as many olfactory sensilla as females at the terminal ecdysis.

Studies to estimate cost-effectiveness and increase longevity of butterflies in live exhibits [PDF]

open access: yes, 2006
Butterfly lifespan and behaviour were quantified using mark-recapture methods and were used to estimate cost-effectiveness of twenty-nine species commonly used in exhibits.

Biochemical Aspects of Juvenile Hormone Action in the Adult Locusta Migratoria by [PDF]

open access: yes, 1966
The present study deals with the action of the juvenile hormone (JH) in the adult Locusta migratoria. It is divided into two parts. The first problem, discussed in chapter 3, is whether or not JH exerts a direct influence on respiratory metabolism.

Juvenile-hormone-mediated plasticity of aggregation behaviour and olfactory processing in adult desert locusts [PDF]

open access: yes, 2001
In desert locusts Schistocerca gregaria, aggregation behaviour is elicited by aggregation pheromones. In this study, we show that the behavioural response to the major and most potent adult aggregation pheromone component, phenylacetonitrile, is age- and

A comparative study of metabolic effects of the corpus allatum in two adult Coleoptera, in relation to diapause [PDF]

open access: yes, 1965
Two problems were studied: a) Whether a lower titre of the corpus allatum hormone had a different influence on the tissues of an adult insect with a diapause mechanism than on those of one without a diapause.
