Predators of Diaprepes abbreviatus (Coleoptera: Curculionidae) Larvae

open access: yesThe Florida Entomologist, 1982
Larvae of Diaprepes abbreviatus (L.) in petri dishes were susceptible to predation on the soil surface in a citrus grove. An average of 47% were removed by predators in the first 20 minutes in a 1979 study to determine rates of predation. Predators (2,613 recorded events) were exclusively ants in the grove studied, with the exceptions of 2 predation ...

Two Muscardine Fungi Pathogenic to Diaprepes Abbreviatus

open access: yesThe Florida Entomologist, 1972
In the laboratory, the fungus Metarrhizium anisopliae (Metschnikoff) Sorokin infected 6.7% of the adults and none of the larvae of the so-called sugarcane rootstalk borer weevil, Diaprepres abbreviatus (L.). In contrast, Beauveria bassiana (Balsamo) Vuillemin infected 92.7% of the adults within 7 days and 76.9% of the larvae within 12 days.

Flight Behavior and Dispersal of Diaprepes abbreviatus

open access: yesThe Florida Entomologist, 1978
From July to October 1975, marked adult Diaprepes abbreviatus (L.) (Coleoptera: Curculionidae) were released in an isolated orange grove near Apopka (Orange County), Florida. Specimens were recovered for 50-52 days following each of 2 releases. Multiple sightings were made of 42% of the released females and 34% of individually coded males.

Biological control of the cherry fruit fly, Rhagoletis cerasi L. (Diptera, Tephriti-dae) by use of entomopathogenic nematodes: first experiences towards practi-cal implementation. [PDF]

open access: yes, 2006
The use of entomopathogenic nematodes (EPN) is a promising approach to control the cherry fruit fly, Rhagoletis cerasi L.. We already demonstrated the high potential of EPN to infect larvae after leaving the cherry for pupation in the soil in laboratory ...
