Repellent and fumigant activity of essential oil from Artemisia vulgaris to Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae)

TL;DR: Repellent and fumigant activity of the essential oil of mugwort, Artemisia vulgaris, against the stored-product insect pest, Tribolium castaneum was investigated and it was confirmed that the Percentage of larvae reaching the pupal stage and the percentage of pupae that reached the adult stage, decreased significantly with increase in dosage concentration.
Journal ArticleDOI

Bioconversion performance and life table of black soldier fly (Hermetia illucens) on fermented maize straw

TL;DR: In this paper, the authors used Aspergillus oryzae larvae for bioconversion of maize straw, which can convert separate or mixed waste, i.e., manure, kitchen waste and straw, into biomass rich in protein and fat.
Journal ArticleDOI

Juvenile hormone facilitates the antagonism between adult reproduction and diapause through the methoprene-tolerant gene in the female Colaphellus bowringi.

TL;DR: The data indicate that JH acts through Met to facilitate development of the reproductive system by upregulating Vg expression while inhibiting diapause by suppressing lipid synthesis and stress tolerance in the cabbage beetle.
Journal ArticleDOI

Fatty acid synthase 2 contributes to diapause preparation in a beetle by regulating lipid accumulation and stress tolerance genes expression.

TL;DR: The results suggest that the absence of JH-Met induces FAS2 expression, thereby promoting lipid storage in diapause-destined female beetles, and demonstrate that fat reserves regulate stress tolerance genes expression and water content, but have no significant effect on the duration of diapsause preparation or the incidence of diAPause.
Journal ArticleDOI

Steroid hormone ecdysone deficiency stimulates preparation for photoperiodic reproductive diapause.

TL;DR: In this article, the authors found that the long day-induced drop in the concentration of the steroid hormone ecdysone is essential for the preparation of photoperiodic reproductive diapause in Colaphellus bowringi, an economically important cabbage beetle.
