Investigation of the Functions of Insect Arginine Vasopressin-like Peptides

Tokach, Rogan; Edwardson, Fenwicht; Kim, Donghun; Park, Yoonseong

The neuropeptide arginine vasopressin (AVP) is a multifunctional signaling peptide that is highly conserved across eukaryotic animals. In mammals, it primarily acts as an anti-diuretic and a regulator of blood pressure. ...

Kazal-type serine proteinase inhibitors in the midgut of Phlebotomus papatasi

Sigle, Leah Theresa; Ramalho-Ortigão, Marcelo (2013-10-21)

Sandflies (Diptera: Psychodidae) are important disease vectors of parasites of the genus Leishmania, as well as bacteria and viruses. Following studies of the midgut transcriptome of Phlebotomus papatasi, the principal ...
Laboratory evaluation of attract-and-kill formulations against the Indianmeal moth, Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae)

Campos, Manuel; Phillips, Thomas W. (2013-04-18)

Pheromone-based population suppression methods for stored-product insects can reduce or eliminate application of chemical insecticides near finished food products. The responses of adult male Indianmeal moth males (IMM), ...
Lampyrids recovered from emergence traps in the Great Smoky Mountains National Park

Buschman, Lawrent L.; Faust, Lynn F. (2014-11-11)

Photinus carolinus Green is a popular firefly that attracts thousands of visitors each year to the Great Smoky Mountains National Park (GSMNP) (Faust, 2009). This firefly is famous for its synchronous flash display in late ...
Larval food supply constrains female reproductive schedules in Hippodamia convergens (Coleoptera: Coccinellidae)

Vargas, German; Michaud, J. P.; Nechols, James R. (2013-02-08)

Reproductive schedules are a critical aspect of life history intrinsically linked to a species' ecology. We explored dynamic trajectories of daily fecundity, egg size, and egg fertility in three size classes of Hippodamia ...
Leishmaniasis: Middle East and North Africa research and development priorities

McDowell, Mary Ann; Rafati, Sima; Ramalho-Ortigão, Marcelo; Salah, Afif Ben (2011-07-26)

Leishmaniasis remains one of the world's most devastating neglected tropical diseases, causing substantial mortality and contributing to nearly 2 million disability-adjusted life years. The true global burden of leishmaniasis, ...
The lethal giant larvae gene in Tribolium castaneum: molecular properties and roles in larval and pupal development as revealed by RNA interference

Xiao, Da; Liang, Xiao; Gao, Xiwu; Yao, Jianxiu; Zhu, Kun Yan (2014-06-17)

We identified and characterized the TcLgl gene putatively encoding lethal giant larvae (Lgl) protein from the red flour beetle (Tribolium castaneum). Analyses of developmental stage and tissue-specific expression patterns ...
Life Cycle of the Soybean Aphid Aphis glycines Matsumura, in Japan

Takahashi, Shigeru; Inaizumi, Mitsumaru; Kawakami, Koji
Life history characteristics of the rove beetle, Dalotia coriaria (Coleoptera: Staphylinidae) under laboratory conditions

Echegaray, Erik R.; Cloyd, Raymond A. (2014-01-22)

Rove beetles (Coleoptera: Staphylinidae) have been reported as predators of animal and human disease vectors and of insect pests associated with field and greenhouse crops including species in the genera Aleochara, Holobus, ...
Life tables for sunn pest, Eurygaster integriceps (Heteroptera: Scutelleridae) in northern Iran.

Iranipour, S.; Pakdel, A. Kahrrazi; Radjabi, G.; Michaud, J. P. (2011-11-04)

Life table studies of sunn pest were carried out in Varamin, Iran, from 1998–2001 in order to determine stage-specific ortalities and the impact of specific natural enemies on population dynamics. Populations were sampled ...
Ligand selectivity in tachykinin and natalisin neuropeptidergic systems of the honey bee parasitic mite Varroa destructor

Jiang, H.; Kim, D.; Dobesh, S.; Evans, J. D.; Nachman, R. J.; Kaczmarek, K.; Zabrocki, J.; Park, Yoonseong (2016-01-28)

The varroa mite, Varroa destructor, is a devastating ectoparasite of the honey bees Apis mellifera and A. cerana. Control of these mites in beehives is a challenge in part due to the lack of toxic agents that are specific ...
Light intensity and wavelength influence development, reproduction and locomotor activity in the predatory flower bug Orius sauteri (Poppius) (Hemiptera: Anthocoridae)

Wang, S.; Tan, X. L.; Michaud, J. P.; Zhang, F.; Guo, X. (2013-11-25)

Light wavelength and intensity are physical factors that can affect arthropod development and reproduction. The present study examined the development, reproduction and locomotor activity of the predatory flower bug, Orius ...
LmCYP4G102: An oenocyte-specific cytochrome P450 gene required for cuticular waterproofing in the migratory locust, Locusta migratoria

Yu, Z. T.; Zhang, X. Y.; Wang, Y. W.; Moussian, B.; Zhu, Kun Y.; Li, S.; Ma, E. B.; Zhang, J. Z. (2016-07-22)

Cytochrome P450 superfamily proteins play important roles in detoxification of xenobiotics and during physiological and developmental processes. To contribute to our understanding of this large gene family in insects, we ...
