“…ripeness or nutritional value, influence the duration of larval development. Similar effects have been reported for other oligo‐ or polyphagous tephritid species, for example, Anastrepha ludens (Loew) (Leyva, Browning, & Gilstrap, ) or C. capitata (Krainacker, Carey, & Vargas, ). While not included in the initial model by Yonow et al (), host fruit may potentially alter life‐history traits and, hence, population dynamics.…”

Around the world, several pest tephritids are extending their ranges from warm tropical or Mediterranean climates into cooler temperate regions. The ability to tolerate climatic diversity is uncommon among insects, and understanding the population phenology drivers of such species across different parts of their range will be critical for their management. Here, we determined the role of temperature versus fruit availability on the population phenology of Queensland fruit fly, Bactrocera tryoni. Using a field site located at the subtropical/temperate interface, with host fruits continuously available, we monitored the development times and abundance of B. tryoni, a species which has invaded temperate Australia from the tropics. From fruit samples held at ambient and controlled conditions, the abundance of emerging flies was highly variable among collection dates, but the variance did not reflect the observed changes in temperature. For most samples, the survival rate of flies in a field site was lower than predicted by a day‐degree population model fitted with mean daily field temperatures. The development time of the immature stage in the field was prolonged, presumably due to cooler ambient conditions, but the fitted day‐degree population model consistently over‐predicted estimated development times. Our results indicate that at the subtropical/temperate interface, the decline in B. tryoni populations during winter is only partly driven by temperature and host availability. We classify B. tryoni as a climate generalist, which likely employs physiological as well as behavioural mechanisms to achieve broad climatic tolerance ranges.

“…Rio Red grapefruit were placed in the infestation cage for 1Ð 4 h; removed; wiped clean; and placed in a chamber at 26.5 Ϯ 0.5ЊC and 78 Ϯ 10% RH until insects were at the proper stage for fumigation. Development is slower in grapefruit than in diet (Leyva et al 1991). Fruit were opened periodically to check insect development.…”

Methyl bromide fumigation is widely used as a phytosanitary treatment. Mexican fruit fly, Anastrepha ludens (Loew) (Diptera: Tephritidae), is a quarantine pest of several fruit, including citrus (Citrus spp.), exported from Texas, Mexico, and Central America. Recently, live larvae have been found with supposedly correctly fumigated citrus fruit. This research investigates the efficacy of the previously approved U.S. Department of Agriculture-Animal and Plant Health Inspection Service treatment schedule: 40 g/m3 methyl bromide at 21-29.4 degrees C for 2 h. Tolerance ofA. ludens to methyl bromide in descending order when fumigated in grapefruit (Citrus X paradisi Macfad.) is third instar > second instar > first instar > egg. Two infestation techniques were compared: insertion into fruit of third instars reared in diet and oviposition by adult A. ludens into fruit and development to the third instar. Inserted larvae were statistically more likely to survive fumigation than oviposited larvae. When fruit were held at ambient temperature, 0.23 +/- 0.12% of larvae were still observed to be moving 4 d postfumigation. Temperatures between 21.9 and 27.2 degrees C were positively related to efficacy measured as larvae moving 24 h after fumigation, pupariation, and adult emergence. Coating grapefruit with Pearl Lustr 2-3 h before fumigation did not significantly affect the proportion of third instars moving 24 h after fumigation, pupariating, or emerging as adults. In conclusion, fumigation with 40 g/m3 methyl bromide for 2 h at fruit temperatures >26.7 degrees C is not found to be inefficacious for A. ludens. Although a few larvae may be found moving >24 h postfumigation, they do not pupariate.

“…For example, A. obliqua lays one egg per oviposition (43) whereas A. grandis can lay clutches of up to 110 eggs (52). The rate of immature-stage development is determined to a great degree by environmental factors such as temperature (14, 99,165) and rearing medium (43, 100), and is sexually dimorphic (173). The larvae of most species feed exclusively on the fruit pulp, although A. manihoti feed on stems and buds (140), and at least some species in the A. serpentina.…”

PERSPECTIVES AND OVERVIEWFlies of the genus Anastrepha (Diptera: Tephritidae) are among the world's most devastating agricultural pests. At the same time, they display remark able ecological and behavioral characteristics, which have served as models in the development of general theories on insect mating systems and the physiology of host marking. Anastrepha species are endemic to the New World and restricted to tropical and sUbtropical environments. The genus's range extends from the southern US to northern Argentina and includes most of the Caribbean Islands. There are 184 described Anastrepha species.The great majority of these are poorly known biologically, and knowledge is basically restricted to seven economically important species: Jraterculus, grandis, ludens, obliqua, serpentina, striata, and suspensa. Much of what we know today about Anastrepha is based on very thorough studies of its basic biology carried out between 1900 and 1944 (13, 53, 85, 115, 188; see also 21, 45, 167). More recently, work has concentrated on phylogeny and taxonomy, behavioral ecology, chemical ecology, demography, and species surveys. Anastrepha control has in many ways been conceptually and technically stagnant for the past 35 years: poisoned bait sprays andMcPhail traps are still standard procedure even though such methods have been proven ineffective and environmentally questionable.Here, rather than providing an all-encompassing review of the voluminous literature on Anastrepha, I attempt to expose the reader to a balanced 155
