Heteroptera Pentatomidae

The mecideine stink bug genus Mecidea is represented in America north of Mexico by three species: Mecidea major Sailor, Mecidea minor Ruckes, and Mecidea longula Stål. M. major and M. minor are widely distributed, occurring collectively from the Midwest to California. M. longula is known only from south Florida. The life histories of M. major and M. minor have been published including laboratory rearing from egg to adult and descriptions of the immature stages. However, no key has been developed for identification of the nymphs of these two species. Here, we present a key to the nymphs of these taxa to the species and instar levels.

AbstractFruit flies (Diptera: Tephritidae) are the most damaging pests on fruit crops on Réunion Island, near Madagascar. Survival and development of the Mediterranean fruit fly, Ceratitiscapitata (Wiedemann), the Natal fruit fly, C. rosa Karsch and the Mascarenes fruit fly, C. catoirii Guérin-Mèneville were compared at five constant temperatures spanning 15 to 35°C. Durations of the immature stages of C. capitata, C. rosa and C catoirii ranged from 14.5–63.8, 18.8–65.7 and 16.8–65.8 days, respectively, at 30–15°C. The lower developmental threshold and thermal constant were calculated using the temperature summation model. The thermal constant for total development of the immature stages of C. capitata, C. rosa and C. catoirii were 260, 405 and 356 DD, respectively. Species differed mainly during the larval stages and ovarian maturation period, with smaller differences in the egg stage. Ceratitis rosa appeared to be better adapted to low temperatures than the two other species as it showed a lower larval developmental threshold of 3.1°C compared to 10.2°C for C. capitata and 8.9°C for C. catoirii. Overall, C. catoirii had a low survival rate within the range of temperatures studied. The different responses of the three Ceratitis species to various temperatures explain to some extent their distribution on the island. The results obtained will be used for optimizing laboratory rearing procedures and for constructing computer simulation models to predict fruit fly population dynamics.

Growth And Survival

Age-specific life and fecundity studies on the weevil Phlyctinus callosus (Boh.) (a polyphagous pest in gardens in parts of southern Australia, especially Victoria) revealed that mortality was greatest in the immature stages and that high temperatures were lethal to eggs (>30 deg C) and larvae (>25 deg C). The intrinsic rate of natural increase was greatest at 20 deg C, and the greater proportion of its value was accounted for early in the egg-laying period. Larvae could be reared on carrot roots in the laboratory; 76% of larvae reared in this manner to the pupal stage passed through 7 instars, 12% through 6, and 12% through 8. Head-capsule width was a suitable criterion for identifying the instars. Eggs could be stored for as long as 12 weeks at 5 deg C with no loss of viability. These results are discussed in relation to control measures against the weevil.
