Food-baited traps are an important part of early detection programs for invasive tephritid fruit fly species, as they attractive to both sexes all targeted species. Torula yeast borax (TYB) mixture is a standard food bait, but its longevity limited (1–2 weeks). Synthetic food-based lures have been developed, including ammonium acetate, putrescine, and trimethylamine. However, the different formulations these synthetic vary greatly in their attractiveness longevity. Here, we present results...

Abstract BACKGROUND Anastrepha fruit flies are considered one of the main phytosanitary problems for fresh industry in USA , Caribbean islands and Latin America. Since 1994, Mexican government has implemented National Fruit Fly Program using an area‐wide integrated pest management approach. In this paper, we evaluate effectiveness mass trapping compare it with ground GF ‐120 spraying against obliqua ludens populations mango cv. Ataulfo orchards.

Population fluctuations of Ceratitis capitata (Wiedemann) were evaluated over a period 12 mo in four altitudinal strata (400–750, 750–1,100, 1,100–1,450, and 1,450–1,800 meters above sea level, masl) Eastern Guatemala. Within each range, sampling plots established coffee plantations adjacent areas, which Jackson traps set baited with Trimedlure. Coffee berries other host fruits collected. density was lowest at the 400–750 masl stratum highest masl. At every pest associated mainly...

Methyl salicylate (MeSA) is an herbivore-induced plant volatile widely tested for attracting natural enemies pest control. MeSA commercially sold as slow-release lures or a spray. While application has increased the abundance of in numerous food crops, its ability to reduce pests crop protection not frequently demonstrated. Our first objective was test ornamental fields where few studies have been done, and monitor enemies, pests, protection. A 2-year study spruce container yards revealed...

Abstract BACKGROUND: Chemosterilisation with lufenuron bait stations is a recently developed technique that being implemented for Ceratitis capitata Wiedemann control. The aim of this work was to evaluate the chemosterilising effect against four economically important Latin American fruit flies species: Anastrepha ludens (Loew.), A. obliqua Macquart, serpentina and striata Schiner (Diptera: Tephritidae) in order design similar strategy their RESULTS: Sexually mature adults were treated by...

The use of insecticide baits is one the most common and efficient methods worldwide to control fruit flies (Diptera: Tephritidae). However, this strategy has commonly been associated with environmental contamination undesirable effects on non-target organisms. lure-and-kill devices (bait stations) or mass trapping could be alternative overcome these ecological concerns. In study, we evaluated several attractants in comparison ground-applied bait sprays for Anastrepha obliqua (Macquart)...

The relationship between different release densities of sterile flies and fly trap captures, expressed as per day, in the monitoring Anastrepha ludens (Loew) populations was evaluated mango orchards. induction sterility fertile females using ratios sterile: males under field cage conditions. A direct recaptured found. However, efficiency, percentage flies, decreased density released increased. Sterility positively correlated to ratio flies. significant difference egg fertility among...

The sterile insect technique (SIT) is an ecologically oriented strategy for pest control and a very important tool establishing low prevalence and/or areas free of fruit flies (Diptera: Tephritidae). This involves releasing highly competitive adults into area with the aim to induce sterility in wild population. Because genetic sexing strains are economical efficient improvement SIT, Moscafrut Program Mexico developed Tapachula-7 (Tap-7) strain Anastrepha ludens (Loew) from which female...

The physiological state of an insect is likely the most important endogenous factor influencing resource-oriented behavior, and it varies considerably among individuals. Trials were conducted in mango orchards to study effect multiple biological factors on response two fly species, Anastrepha ludens (Loew) obliqua Maquart (Diptera: Tephritidae), BioLure NuLure baits. species that tested following: 1) fertility status-sterile (irradiated) fertile flies; 2) types diets (only sugar a 3:1...

Abstract Beauveria bassiana is an entomopathogenic fungus widely used to control different insect pests including Anastrepha ludens (Diptera: Tephritidae), a key pest of citrus and mangoes. Currently, this pest, sterile A. males the Tap‐7 genetic sexing strain are released weekly by aircraft at density 1,000 males/ha as part integrated management programme (IPM) in Southern Mexico. Our objective here was determine whether technique (SIT) could be enhanced augmenting it with horizontal...

Abstract We aimed to estimate population densities of A nastrepha obliqua (McQuart) ( D iptera: T ephritidae) from trap data by releasing known numbers sterile adults into mango orchards, and determine sterility induction through the use different sterile‐to‐wild ratios in field cages. Population were monitored with Multilure traps baited hydrolysed protein (Captor 300) or BioLure during dry rainy seasons. There was a positive relationship between release density flies number trapped per day...

The Mediterranean fruit fly, Ceratitis capitata (Wiedemann), is an exotic pest of economic importance in several parts the world. Systems for monitoring this employ mainly trimedlure (TML), a parapheromone specifically males. Understanding performance these attractants under different conditions should contribute to better design trapping networks, field data interpretation, and more efficient use products. In study, release rate TML was determined at 15, 25, 35 °C, through plug weight loss...
