Advances in understanding the mitogenic, metabolic, and cell death signaling in teleost development: the case of greater amberjack (Seriola dumerili, Risso 1810)
(2022)Cell growth and differentiation signals of insulin-like growth factor-1 (IGF-1), a key regulator in embryonic and postnatal development, are mediated through the IGF-1 receptor (IGF-1R), which activates several downstream ... -
Are insect meals prone to insect infestation during storage? Development of major storage insects on substrates based on Tenebrio molitor larvae meal
(2020)Insect meal is a new agricultural commodity that will be produced in huge quantities in the near future and will be treated as all traditional agricultural commodities, i.e., insects will be harvested, processed, transported ... -
Assessment of selected larvicides for the control of Culex pipiens biotype pipiens and Culex pipiens biotype molestus under laboratory and semi-field conditions
(2020)BACKGROUND: The insecticidal efficacy of selected mosquito larvicides [teflubenzuron, S-methoprene, diflubenzuron, temephos, Bacillus thuringiensis var. israelensis (Bti) and polydimethylsiloxane (PDMS)], applied alone or ... -
Biological activity of two new pyrrole derivatives against stored-product species: Influence of temperature and relative humidity
(2016)Members of the pyrrole group are likely to have interesting properties that merit additional investigation as insecticides at the post-harvest stages of agricultural commodities. In the present work, the insecticidal effect ... -
Comparative Population Growth of the Khapra Beetle (Coleoptera: Dermestidae) and the Warehouse Beetle (Coleoptera: Dermestidae) on Wheat and Rice
(2022)We evaluated the relative population growth of two stored-product insect species in the genus Trogoderma, the khapra beetle, Trogoderma granarium Everts (Coleoptera: Dermestidae), and the warehouse beetle, Trogoderma ... -
Curcumin derivatives as potential mosquito larvicidal agents against two mosquito vectors, culex pipiens and aedes albopictus
(2021)Vector-borne diseases have appeared or re-emerged in many Southern Europe countries making the transmission of infectious diseases by mosquitoes (vectors) one of the greatest worldwide health threats. Larvicides have been ... -
Development and diapause induction of the Indian meal moth, Plodia interpunctella (Hübner) (Lepidoptera: Pyralidae) at different photoperiods
(2020)Diapause concerns the fascinating phenomenon in the biology of insect development which allows better understanding the local adaptation and phenotypic plasticity to seasonal variations in environment. There is lot of ... -
Differential response to larval crowding of a long- and a short-lived medfly biotype
(2020)Response of endophytic fruit fly species (Tephritidae) to larval crowding is a form of scramble competition that may affect important life history traits of adults, such as survival and reproduction. Recent empirical ... -
Effect of hellebore (Helleborus odorus Waldst. & Kit. ex Willd.) plant extract on the progeny and survival of the larvae of stored product pests
(2022)Plant extracts have been used as pest control tools for years, whole or as the basic element in developed insecticides. Helleborus odorus Waldst. & Kit. ex Willd (Ranunculales: Ranunculaceae) extract exhibits pharmaceutical ... -
Effect of host fruit, temperature and Wolbachia infection on survival and development of Ceratitis capitata immature stages
(2020)The Mediterranean fruit fly, Ceratitis capitata (Diptera: Tephritidae), holds an impressive record of successful invasions promoted by the growth and development of international fruit trade. Hence, survival of immatures ... -
Effect of larval density on development and diapause of Sesamia nonagrioides (Lef.) (Lep., Noctuidae) under laboratory conditions
(1999)The effect of larval density on development and diapause of Sesamia nonagrioides (Lef.) was examined. Larvae were grown on an artificial diet at densities of five, 10, 20, 30 and 40 larvae per box, under two environmental ... -
Effect of the combined application of microencapsulated synthetic oviposition pheromone (MSP) with different larvicidal agents on the oviposition of Culex pipiens biotype molestus
(2018)BACKGROUND: Attract-and-kill strategies, in which a behavior-modifying stimulus (e.g. a pheromone) is integrated with a pest control agent, have lately attracted increased interest for mosquito control. Previously, it was ... -
The effect of Trichinella spiralis on muscular activity of experimentally infected mice
(2020)Nematodes of genus Trichinella are wide-spread zoonotic parasites, able to infect a large variety of vertebrates. Animal hosts are usually regarded as asymptomatic carriers. However, there is little data regarding the ... -
Efficacy of polydimethylsiloxane against Culex pipiens (Diptera: Culicidae)
(2021)We evaluated, under controlled laboratory conditions, the insecticidal activity of polydimethylsiloxane (PDMS) for the control of the house mosquito, Culex pipiens. In a first series of bioassays, we tested the residual ... -
Evaluation of Mating Disruption for the Control of Thaumetopoea pityocampa (Lepidoptera: Thaumetopoeidae) in Suburban Recreational Areas in Italy and Greece
(2019)Thaumetopoea pityocampa (Denis and Schiffermüller) is a severe defoliator of various species of Pinus and Cedrus, while the urticanting hairs produced by its larvae cause public health problems for humans and pets. In the ... -
Evaluation of various commodities for the development of the yellow mealworm, Tenebrio molitor
(2020)We evaluated the suitability of forty-four commodities (i.e., cereal flours and meals, non-flour, cereal commodities, legumes and various commodities of vegetative and animal origin) as oviposition and feeding substrates ... -
Gastrointestinal trichostrongylosis can predispose ewes to clinical mastitis after experimental mammary infection
