    The Citrus Root Weevil The citrus root weevil, Diaprepes abbreviatus, is a large colorful weevil that is native to the Caribbean Islands. This weevil was accidentally introduced into Florida in the 1960’s where it has caused extensive damage. It has been intercepted in shipments of plants to California. This weevil will feed on about 270 different plants including citrus, guava, loquat, holly, and other ornamentals. An adult citrus root weevil (approximate size a to w inch in length). 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012345678901234 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012345678901234 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012345678901234 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012345678901234 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012345678901234 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012345678901234 12345678901234567890123456789012123456789012345678901234567890121234567890123456789012345678901212345678901234567890123456789012123456789012345678901234

Fungal entomopathogens provide an attractive alternative to synthetic insecticides for weevil control because they pose a lesser risk to human health and the environment. This review summarises the available data on the performance of these entomopathogens when used against weevils in horticultural crops. We integrate these data with information on weevil biology, grouping species based on how their developmental stages utilise habitats in or on their hostplants, or in the soil.

  • Biocontrol of the Sugarcane Rootstalk Borer, Dioprepes Abbreviatus (L) (Coleoptera: Curculionidae), with Entomophilic Nematodes
    Biocontrol of the sugarcane rootstalk borer, Dioprepes abbreviatus (L) (Coleoptera: Curculionidae), with entomophilic nematodes Wilfredo FiguerooS and Jesse Roman* ABSTRACT Eight greenhouse trials evaluated the efficacy of three species of en­ tomophilic nematodes of the genus Steinernema ( = Neoaplectana) in con­ trolling neonate and 6-, 10-, and 14-week-old larvae of the sugarcane rootstalk borer (SRB), Diaprepes abbreviatus (L.)r in sugarcane. Different densities of the nematodes Steinernema feltiae Filfp[ev, S. glaseri Steiner, and 5, bibionis Bobien were tested. The infective nematodes controlled the 6- to 14-week-old (0.64 to 2.54 cm) larvae. Significant results were also observed on the control of the effect of the larvae on sugarcane in the various parameters measured. No significant effects were observed with neonate (first instar) larvae. Larval mortality increased with age. Eighty- five percent mortality of 10-week-old grubs was observed at 240,000 nematodes per 1.8 kg of soil with a surface area of 0.02 m.2 Control of 10-week-old grubs was also possible at 480,000 nematodes per 3.6 kg of soil with a surface area of 0.03 m.2 Fourteen-week-old grubs were the most susceptible to the attack of 5. feltiae. S. glaseri is more effective than S, bibionis in controlling the grubs, but the effect of 5, glaseri on the grubs is less consistent than that of S. feltiae. The three species of Steinernema performed well at temperatures of 20° to 31° C.

Am. 93(3): 459Ð467 (2000) ABSTRACT Genetic differentiation among six Florida populations of Diaprepes abbreviatus (L.) was determined using protein and random ampliÞed polymorphic DNA-polymerase chain reaction (RAPD-PCR) markers. Proteins were separated by electrophoresis and stained with silver stain and for ␣-naphthylacetate esterase activity. No differentiation was observed among populations when egg proteins were silver stained: ␣-naphthylacetate esterase activity differentiated Þve of the six populations. RAPD-PCR data showed signiÞcant differentiation among populations, consistent with the hypothesis of three independent introductions of D. abbreviatus into Florida. Our data indicate that D. abbreviatus populations, once introduced, have generally remained in one locality with limited dispersal to new areas.

Although Oxisols lionidae) is an insect whose host range includes occupy a relatively small percentage of Puerto more than 270 species of plants, including many Rico’s surface, tropical fruit crops are commonly economic species (Martorell 1976; Simpson et al. grown in this soil type and sustain significant 1996; Wolcott 1936).

Received: 1 August 2018; Accepted: 20 August 2018; Published: 23 August 2018 Abstract: The Entiminae are broad-nosed weevils constituting the most diverse subfamily of Curculionidae, with over 50 tribes. We performed Bayesian and Maximum Parsimony combined phylogenetic analyses with the main objective of testing higher-level relationships and the naturalness of the major Neotropical and Southern South American (Patagonia and Andes) tribes, including some members from other regions. We compiled a data matrix of 67 terminal units with 63 Entiminae species, as well as four outgroup taxa from Cyclominae, by 3522 molecular (from nuclear 18S rDNA and 28S rDNA, and mitochondrial 16S rDNA and COI gene sequences) and 70 morphological characters. The resulting trees recover a clade Entiminae with a monophyletic Cylydrorhinini and Premnotrypes branching off early.
