twin reversed arterial perfusion (trap) sequence is a syndrome with poor prognosis, seen only in monochorionic monozygotic twin pregnancies. the incidence is one in 35.000 births and one in 100 monozygotic twin pregnancies. it is characterized with a recipient fetus exhibiting lethal anomalies including acardia and a pump fetus. mortality is usually due to heart failure or premature labor cause...

The codling moth (Cydia pomonella) is probably the most harmful pest in apple and pear orchards. crop loss due to high harmfulness of insect can be extremely expensive; therefore, sophisticated management necessary protect crop. conventional monitoring approach for swarming has been based on traps that are periodically checked by human operators. However, this workflow automatized. To achieve g...

In the present work, a one pot, rapid and room temperature photochemical Synthesis of transition metal (TM; Cu, Mn, Cr)-doped ZnSe/ZnS core/shell nanocrystals (NCs) was reported. FT-IR spectrum confirmed the capping of ZnSe by thioglycolic acid. XRD and TEM analysis demonstrated zinc blende phase NCs with an average size of around 3 and 5 nm for TM:ZnSe and TM:ZnSe/ZnS NCs, respectively. PL spe...

The three key lepidopteran pests of cole, Brassica oleracea L., crops in North America are diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae); cabbage looper; Trichoplusia ni (Hübner) (Lepidoptera: Noctuidae); and imported cabbageworm, Pieris rapae (L.) (Lepidoptera: Pieridae). Two species-specific pheromone-based experimental attracticide formulations were evaluated against ...

Root-knot nematodes (RKNs, genus Meloidogyne) are a class of plant parasites that seek out and infect the roots many species. The identification RKN attractants can be used in agriculture conjunction with nematode-trapping technology to redirect movements eventually reduce their prevalence field. Here, we discovered some commercial silica gels attract nematodes. Silica contain calcium sulfate. ...

It has been suggested that increasing plant species diversity (PSD) in agroecosystems at different spatiotemporal scales reduces the impacts of crop pests and diseases as well dependence on synthetic protection products. This principle was applied to a range tropical case studies. These studies involved various pathogens with contrasting life history traits, cropping systems (a cereal conservat...
