Plant-parasitic nematodes are present on maize but resistant genotypes have not been identified in Uganda. This study was aimed at determining the level of nematode resistance among F(1) hybrids, and to estimate grain yield, heterosis and yield losses associated with maize hybrids under nematode infestation. The 30 F(1) hybrids and two local checks were evaluated in a split plot design with nem...

The research experiment was conducted at the Department of Horticulture’s, SHUATS, Prayagraj during year 2022.The laid out in Randomized Block Design comprising 9 varieties viz., V1: All Green, V2: Space Spinach, V3: Red kitten V4: Catalina V5: Bloomdale, V6: Perpetual V7: Indian summer V8: Punjab V9: Corvair spinach with three replications. Observations were recorded as per growth and yield pa...

Cytosolic fructose-1,6-biphosphatases (FBPase, EC 3.1.3.11) from pea (Pisum sativum L. cv Lincoln) and spinach (Spinacia oleracea L. cv Winter Giant) did not cross-react by double immunodiffusion and western blotting with either of the antisera raised against the chloroplast enzyme of both species; similarly, pea and spinach chloroplast FBPases did not react with the spinach cytosolic FBPase an...

Giardia, a protozoan parasite, resides in the small intestine in man. This parasite damages the mucosal intestinal surface and in severe cases produces malabsorption and it may also affect mineral absorption, especially zinc. In this study a total of 118 infested and 43 non-infested persons as a control group were selected. From each patient a 5 ml blood sample was obtained. The serum was ...

Alfalfa (Medicago sativa L. cv. Saranac) seed were soaked for 20 minutes in water, acetone, or methanol containing 10 or 50 mg/ml of oxamyl (Vydate L) or coated with a 2% aqueous cellulose solution containing the same amounts of oxamyl. Seed were analyzed for oxamyl by HPLC immediately after treatment and after 9 and 26 months of storage. Oxamyl content of alfalfa seed did not decline after 26 ...

The objective of the study was to evaluate itchingoccasionally observed in cats and dogs shortly afteradministration of nitenpyram(Capstar; NovartisAG, Basel, Switzerland).Twelve cats and twelve dogs were caged individual-ly, infested with 100 fleas, and dosed with niten-pyram 24 hours later. Cats and dogs were dosed withtablets containing 11.4 mg and 57.0 mg nit...

BACKGROUND The whitefly, Bemisia tabaci (Hemiptera: Aleyrodidae), is one of the most widely distributed agricultural pests. In recent years, B. tabaci Q has invaded China, and Q has displaced B in many areas now. In a number of regions of the world, invasion by B and/or Q has been followed by outbreaks of tomato yellow leaf curl virus (TYLCV). Our previous study showed TYLCV directly and indire...

Studying distribution is necessary to understand and manage the dynamics of species with spatially structured populations. Here we studied the distribution in Tetranychus evansi and T. urticae, two mite pests of tomato, in the scope of evaluating factors that can influence the effectiveness of Integrated Pest Management strategies. We found greater positive density-dependent distribution with T...

An isolate of cucumber mosaic virus (CMV) was identified from spinach in the Winter Garden area a of Texas. The isolate was very closely related serologically to strain S of CMVand is designated the Texas spina...
