Iological and behavioral aspects of two laboratory strains of ceratitis capitata (diptera: tephritidae): the influence of periodic introduction of wild flies in the colony

The healthy maintenance of insects reared under laboratory conditions requires strategies to retain the natural characteristics of their life-histories traits. Rearing strategies include artificial selection to laboratory conditions, hybridization with compatible strains, and supplying the colony with wild individuals. We compared behavioral as well as life-history aspects of two laboratory strains of Ceratitis capitata Wiedemann (Diptera, Tephritidae) that had either been reared for 15-20 years under laboratory conditions with or without introducing wild specimens (Lab-Pop and Hybrid-pop, respectively). The parameters evaluated were: performance and food ingestion of immatures, adult size and longevity, female oviposition preference and fecundity, egg viability, and mating choice. Analyses of these parameters were conducted under laboratory rearing conditions. The largest differences observed between the two strains were related to behavioral components: food ingestion rate at the larval stage and oviposition behavior. In general, Lab-Pop individuals were less selective and more adapted to the artificial diet than Hybrid-Pop individuals (diet consumption), but there were no significant differences between the two strains in terms of percentage of emergence, egg viability, adult size, fecundity, and mating choice. It is suggested that the use of hybrid strains is more appropriate than the use of strains without the incorporation of wild individuals, especially in studies that involve behavioral parameters, as hybrid strains behave very similarly to wild populations, according our previous studies.

ABSTRACT: The objective of this study was to compare the use of fruits of great economic and social importance for the northeast of Brazil by Ceratitis capitata Wied. (Diptera: Tephritidae) for oviposition, larval development, size and longevity of adults. Fruits of mango (Mangifera indica L.), quiabento (Pereskia bahiensis Gürke), forage palm [Opuntia fícus indica (L.) Mill] and grape (Vitis vinifera L.) were used, as well as flies from a hybrid laboratory population. Initially, four treatments (fruits) and six replications were used; the fruits were offered to 10 C. capitata couples, with later (96 hours) egg count. The second was conducted with six treatments and 10 replicates, offering two types of fruits simultaneously, combined two to two, to 10 C. capitata couples. The last bioassay comprised four treatments and six replicates, where 20 g of fruit were offered to 20 first-instar C. capitata larvae. After six days, the larvae were placed in plastic pots containing vermiculite until pupation, quantifying larval and pupal periods, viability and pupal mass, besides longevity and adult size. The data were submitted to ANOVA using the R Core Team software. Ceratitis capitata oviposits and completes its biological cycle in the four hosts studied, exhibiting no preference for oviposition and low biological performance in quiabento fruits. It yielded smaller adults and lower grape survival. Cactaceae palm and quiabento allow the survival of C. capitata in the laboratory, and this knowledge has been reported for the first time, proving that they can act as alternative hosts in the field.

And Performance

Abstract A better understanding of the factors affecting host plant use by spotted-wing drosophila (Drosophila suzukii) could aid in the development of efficient management tools and practices to control this pest. Here, proxies of both preference (maternal oviposition behavior) and performance (adult emergence) were evaluated for 12 different fruits in the form of purees. The effect of the chemical composition of the fruits on preference and performance traits was then estimated. We synthesized the literature to interpret our findings in the light of previous studies that measured oviposition preference and larval performance of D. suzukii. We show that fruit identity influences different parts of the life cycle, including oviposition preference under both choice and no-choice conditions, emergence rate, development time, and number of emerging adults. Blackcurrant was always among the most preferred fruit we used, while grape and tomato were the least preferred fruits. Larvae performed better in cranberry, raspberry, strawberry, and cherry than in the other fruits tested. We found that fruit chemical compounds can explain part of the effect of fruit on D. suzukii traits. In particular, oviposition preference under choice conditions was strongly influenced by fruit phosphorus content. In general, the consensus across studies is that raspberry, blackberry, and strawberry are among the best hosts while blackcurrant, grape and rose hips are poor hosts. Our results generally confirm this view but also suggest that oviposition preferences do not necessarily match larval performances. We discuss opportunities to use our results to develop new approaches for pest management.

ABSTRACT The use of toxic baits with spinosyns (spinosad and spinetoram), along with the parasitoid Diachasmimorpha longicaudata, is a sustainable alternative for the management of Ceratitis capitata. This study aimed to evaluate the lethal concentration (LC) and lethal time (LT) of spinosad and spinetoram, associated with the food lures sugarcane molasses at 7 %, Biofruit at 3 %, Ceratrap® at 1.5 %, Flyral® at 1.25 %, Isca Samaritá® and Samaritá Tradicional® at 3 %, on C. capitata, under laboratory conditions, as well as their effect, at the concentration of 96 mg L-1, on D. longicaudata. For the lethal time data, mortality was assessed at 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 36, 48, 60, 72, 84 and 96 h after the exposure to the toxic baits. The lowest lethal concentrations (LC50 and LC95), to spinetoram (0.5 mg L-1 and 3.7 mg L-1, respectively) and spinosad (0.8 mg L-1 and 7.8 mg L-1, respectively), corresponded to the association with Samaritá Tradicional® at 3 %. The lowest lethal time (TL50), in hours, for the spinosad insecticide, corresponded to the formulation containing Biofruit at 3 % (6.6), and, to spinetoram, Samaritá Tradicional® at 3 % (7.9). For D. longicaudata, the formulations that caused the lowest mortality corresponded to the association of Biofruit® at 3 % with spinosad (4.7 %) and Samaritá Tradicional® at 3 % with espinetoram (3.5 %). The toxic baits formulated with spinosad and espinetoram, associated with Isca Samaritá® at 3 %, caused a mortality rate of more than 60 % to the parasitoid D. longicaudata.

Typhlodromus pyri Scheuten (= T. tiliae Oudms.) is the predominant species of predacious mite on apples in Nova Scotia. It feeds on a wide range of prey species (Herbert, 1959). Chant (1960) investigated the life-history and habits of this species in southeastern England and Herbert (1956) studied its life-history under controlled laboratory conditions. A knowledge of the life-histories of various components of the fauna is basic to an evaluation of predation; therefore, a study of the life-history and habits of T. pyri in the field was undertaken. This was supplemented by a laboratory study in which an attempt was made to duplicate field temperarures. The results of these studies are presented here.
