Development of Diaprepes abbreviatus on Potted Citrus Seedlings
The Florida Entomologist, 1975 Adult Diaprepes abbreviatus (L.) were recovered from citrus seedlings 132 through 168 days after infestation of the plants with 0- to 24-hour old larvae. Pupae were recovered 98 through 238 days after infestation. The number of larval instars could not be determined from the frequency distribution curves of head capsule measurements.

EDIS, 2003 The predatory stink bug, Euthyrhynchus floridanus (Linnaeus), is considered a beneficial insect because most of its prey consists of plant-damaging bugs, beetles, and caterpillars.

Predators of Diaprepes abbreviatus (Coleoptera: Curculionidae) Larvae
The 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
The 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.

Root Weevil Management: Above and Below Ground
EDIS, 2018 Root weevils are a major pest group for many kinds of plants, with at least nine species that colonize citrus. Species commonly infesting citrus include Diaprepes root weevil (Diaprepes abbreviates), blue-green citrus root weevils (Pachnaeus litus and ...

Subterranean, herbivore-induced plant volatile increases biological control activity of multiple beneficial nematode species in distinct habitats. [PDF]
PLoS ONE, 2012 While the role of herbivore-induced volatiles in plant-herbivore-natural enemy interactions is well documented aboveground, new evidence suggests that belowground volatile emissions can protect plants by attracting entomopathogenic nematodes (EPNs ...

Sources of Resistance to Diaprepes Weevil in Subfamily Aurantiodeae, Rutaceae [PDF]
HortScience, 2001 Commercially used citrus rootstocks can all be seriously damaged by larvae of the sugar cane root weevil, Diaprepes abbreviatus (L.). Six greenhouse challenge experiments were used to compare the resistance of 24 selections of citrus rootstocks and related species to this weevil by measuring ...

Ovipositional Preferences of Diaprepes abbreviatus (Coleoptera: Curculionidae)
The Florida Entomologist, 1998 Female Diaprepes abbreviatus L. were presented with immature citrus leaves, mature citrus leaves, and doubled strips of various substances as potential oviposition sites. In both the laboratory and in caged outdoor experiments more egg masses were deposited between freezer paper strips than between mature leaves.

Observations on the Oviposition Process of Diaprepes abbreviatus (Coleoptera: Curculionidae)
The Florida Entomologist, 1999 A single adult Diaprepes abbreviatus L. was discovered in a citrus nursery in Orange County Florida (Woodruff 1964). D. abbreviatus was not collected again until 1968, when larvae were collected at the same nursery and several hundred adults and larvae were subsequently collected in and around Apopka, FL (Woodruff 1968). Since its introduction in 1964,
