Maltase 1 regulates DENV2 infection and life history in Aedes aegypti

Insect Science, EarlyView.
Our study employed CRISPR/Cas9 to generate a MAL1 knockout strain of Aedes aegypti, demonstrating that the absence of MAL1 significantly suppresses DENV2 replication in the midgut and impairs viral transmission. The mutation also altered life‐history (hatching/pupation/emerging rates and sex‐specific survival), identifying MAL1 as a novel target for ...

RÉTENTION DES OVULES APRÈS OVULATION DANS LA CAVITÉ OVARIENNE DE LA CARPE HERBIVORE : COMPOSITION DES OVULES ET CAPACITÉ DE DÉVELOPPEMENT DES ŒUFS ET DES ALEVINS.

Knowledge and Management of Aquatic Ecosystems, 2002
Pour étudier l’effet de rétention prolongée des ovules dans la cavité ovarienne (in vivo) de la carpe herbivore, des extractions d’ovules de 15 femelles (3 à 5,6 kg) ont eu lieu à différents intervalles de temps après ovulation (0, 30, 60, 90 et 120 min).

Environmental Effects On Drosophila Brain Development And Learning [PDF]

, 2017
Brain development and behavior are sensitive to a variety of environmental influences including social interactions and physicochemical stressors. Sensory input in situ is a mosaic of both enrichment and stress, yet little is known about how multiple ...

The shibirets4 mutation causes temperature sensitive paralytic and lethal phenotypes in the Queensland fruit fly, Bactrocera tryoni

Insect Science, EarlyView.
Abstract Bactrocera tryoni, the Queensland fruit fly, is among the most damaging insect pests to the Australian horticultural industry as larvae infest ripening fruits or vegetables prior to harvest. Genetic biocontrol using Sterile Insect Technique (SIT) programs have been used to successfully suppress populations, via mass release of factory‐reared ...

Two Triflumuron Application Methods on Glossina palpalis gambiensis in the Laboratory: Impact on Female Fertility

Revue d’Elevage et de Médecine Vétérinaire des Pays Tropicaux, 2003
The objective of this study was to compare the efficacy of two triflumuron-application methods on male tsetse flies to achieve transfer of the product to the females during subsequent mating.

Life History, Damage, and Gall Development of the Gall Midge, \u3ci\u3eNeolasioptera Brevis\u3c/i\u3e (Diptera: Cecidomyiidae), Injurious to Honeylocust in Michigan [PDF]

, 2017
Neolasioptera brevis is univoltine in Michigan. Adults issue in late spring, and females deposit eggs in rows on the lower side of young shoots of honeylocust. Larval eclosion occurs shortly after: there are three larval instars.

Sequence and expression analysis of potential spermatogenesis‐specific gene cognates in the Caribbean fruit fly, Anastrepha suspensa

Insect Science, EarlyView.
Abstract The sterile insect technique (SIT) is a highly effective biologically‐based method for the suppression of many insect pest populations. SIT efficacy could be improved by methods of male sterilization that avoid the use of irradiation that can result in diminished fitness and mating competitiveness.

Multi-objective optimization shapes ecological variation [PDF]

, 2013
Ecological systems contain a huge amount of quantitative variation between and within species and locations, which makes it difficult to obtain unambiguous verification of theoretical predictions.

Co-evolution of male and female reproductive traits across the Bruchidae (Coleoptera) [PDF]

, 2008
1. Despite the obvious importance of spermatozoa to individual reproductive success a general explanation of variation in spermatozoan form and function is still lacking. In species with internal fertilization, sperm not only have to interact with the
