Five protein sources were tested: Casein, Nu lure(tm) (a protein diet derived from corn, Miller Chemical and Fertilizer Corporation, USA), protein hydrolysate and Torula yeast
, in different concentrations (1, 3, 5 and 7g/ml) were compared with standard diet containing sucrose (5 mg), brewer's yeast (1 mg), honey (1 mg) and water (500 ml) in the Bio-control, Mass Rearing Laboratory, Nuclear Institute of Agriculture (N.I.A.), Tando Jam, Pakistan under the controlled conditions described above.
Among the plant protein sources, fishmeal with torula yeast
produced the highest growth rate (91 [micro]m/day) (Table 5).
Eight attractants were used in the study: (1) sugar mixture: a homemade sugar solution with vinegar and wine mixture (10 g sugar, 5 g ethylic acid, and 3 mL alcohol in 100 mL water); (2) torula yeast
: 3 pellets per 300 mL water (Chemtica Internacional S.A., Santa Rosa, Costa Rica); (3) Great bait: Great"fruit fly bait, a protein-based bait, 1:3 (vokvol) solution at the recommended application rate (Hubei Great" Biotech Co.
Mineral composition of torula yeast
(Candida utilis) grown on distiller's vinasse.
A torula yeast
factory is located at the Perucho Figueredo mill, and alcohol is produced at the Heriberto Duquesne sugar mill.
Comparison of torula yeast
and various grape juice products as attractants for Mexican fruit fly (Diptera: Tephritidae).
The downsizing of Cuba's sugar industry sharply cut the supply of molasses, torula yeast
and other valuable nutritional supplements.
In addition, torula yeast
and press bagasse boards were produced at the recently dismantled Aracelio Iglesias and Simon Bolivar mills.
2011) have investigated traps for silk flies and have used molasses, fresh corn, torula yeast
, and a hydrolyzed corn protein preparation, Bio Anastrepha (Biocontrole Metodos de Controle de Pragas Ltda., Indaiatuba, Brazil) as bait.
Each trap was baited with 2 pellets (5 g) of Torula Yeast
with borax (ERA Intl., Baldwin, New York) dissolved in 250 mL of water.
In addition to sugar, the province's mills also produce alcohol and torula yeast
The objective of the present study was to gather additional data regarding captures of a closely related species, the melon fly, Zeugodacus cucurbitae (Coquillett), in traps baited with a torula yeast
and borax (TYB) solution (a standard food lure) compared with traps baited with the cucumber volatile (CV) plug.
