“…or Beauveria sp., have demonstrated a significant reduction in feeding as early as 1 to 4 days after inoculation (99). Feeding then decreases through time until death (26). Several studies have shown that the reduction in feeding is associated with dose, e.g., at the highest dose of Metarhizium anisopliae var.…”

“…These studies show that although insects killed by entomopathogenic fungi often take longer to die than if treated with chemical pesticides, damage to crops is decreased during the disease incubation period because infected insects eat less than healthy ones. Studies evaluating food consumption and infection have focused on phytophagous hosts, including lepidopteran larvae (33, 35, 37, 99), acridids (1, 15,101), and coleopterans (20,26). Most studies investigating insect species infected with the hypocrealean fungi, Metarhizium sp.…”

Invertebrate pathogens and their hosts are taxonomically diverse. Despite this, there is one unifying concept relevant to all such parasitic associations: Both pathogen and host adapt to maximize their own reproductive output and ultimate fitness. The strategies adopted by pathogens and hosts to achieve this goal are almost as diverse as the organisms themselves, but studies examining such relationships have traditionally concentrated only on aspects of host physiology. Here we review examples of host-altered behavior and consider these within a broad ecological and evolutionary context. Research on pathogen-induced and host-mediated behavioral changes demonstrates the range of altered behaviors exhibited by invertebrates including behaviorally induced fever, elevation seeking, reduced or increased activity, reduced response to semiochemicals, and changes in reproductive behavior. These interactions are sometimes quite bizarre, intricate, and of great scientific interest.

“…However, there are not studies about this effect on A. grandis. France et al (2002) evaluated four native isolates of B. bassiana for food consumption over time in adults of the weevil Asynonychus cervinus (Coleoptera: Curculionidae), and found that food intake of infected insects decreases through time until death. Ekesi (2001), who evaluated antifeedant activity of B. bassiana against the cowpea leaf beetle Ootheca mutabilis (Coleoptera: Chrysomelidae), observed that daily food consumption between treated and control insects was significantly lower after 2 d of treatment.…”

“…As injúrias observadas nas folhas novas de café da área de rebrota são semelhantes àquelas citadas na literatura (FRANCE et al, 2002;JUNQUEIRA, 1952;STURMER et al, 2006). Os adultos fazem cortes em forma de meia-lua nas bordas das folhas, podendo consumir uma área foliar considerável (Figura 2B).…”

“…Os adultos fazem cortes em forma de meia-lua nas bordas das folhas, podendo consumir uma área foliar considerável (Figura 2B). Segundo France et al (2002), N. cervinus têm hábitos gregários e se alimentam preferencialmente da margem das folhas, brotos, talos tenros e flores. Em folhas de citros, Guedes et al (2007) registraram para N. cervinus um consumo foliar total de 15,0 cm 2 de folhagem.…”

RESUMONaupactus cervinus é uma espécie altamente polífoga e já foi registrada causando danos a diversas culturas em vários Estados brasileiros. Objetivou-se, neste trabalho, registrar, pela primeira vez, a ocorrência de N. cervinus em cafeeiros na região da Zona da Mata Mineira, além de descrever os danos e a infestação numa plantação de café. Foi constatada uma infestação em rebrota de café, cultivar Catuaí, na região da Zona da Mata mineira. Ao se alimentarem, os adultos recortam os bordos das folhas novas deixando-as com aspecto de meia lua. Constatou-se uma média de 2,1 ± 0,3 insetos por planta e a grande maioria das plantas analisadas estava dentro da classe de plantas com menos de 25% de folhas atacadas.Termos para indexação: Café, injúrias, besouro desfolhador, Curculionidae. ABSTRACTNaupactus cervinus is a species highly polyphagous that has already been registered causing damages to many crops in several States of Brazil. This paper aims to register, for the first time, the occurrence of N. cervinus in coffee trees in the State of Minas Gerais, as well as to describe damages and infestation in a coffee plantation. An infestation was observed in a coffee sprout replantation, variety Catuaí, in the area of Zona da Mata of Minas Gerais. In feeding, adults of N. cervinus cut out the borders of tender leaves giving them an aspect of moon in first quarter. One verified an average of 2,1 ± 0,3 insects for tree and the majority of analyzed plants was inside the class of plants with less than 25% of attacked leaves.
