Abstract:
... A low-cost simplified diet has been successfully developed for rearing Spodoptera exigua larvae under laboratory conditions. The cost of ingredients was lower than that of the standard diet based on a modified tobacco hornworm, Manduca sexta (L.), diet. The simplified diet fulfilled larval nutritional requirements without apparent adverse effects on the reproductive capacity of the insect. Surviva ...

Abstract:
... Bites from the recluse or brown spiders (genus Loxosceles) can cause necrotic lesions and systemic effects in humans throughout the world. In the state of Paraná, Brazil, loxoscelism is considered a serious public health problem, and Loxosceles intermedia Mello-Leitão (Araneae: Sicariidae) is associated with the majority of reported accidents. In the present research we evaluated the susceptibilit ...

Abstract:
... The percentage of viable eggs of the western corn rootworm, Diabrotica virgifera virgifera LeConte, which survived to the adult stage was evaluated for the effect of egg density in 2005 and 2007 in central Missouri. In 2005, each plot was 2.44 by 3.05 m and contained 64 maize (corn), Zea mays L., plants. In 2007, plots were 3.05 by 3.05 m and again contained 64 corn plants. Seven egg densities (2, ...

Abstract:
... The application of insecticides to control Diaphorina citri Kuwayama (Hemiptera: Psyllidae) is a principal component of the current management for citrus greening disease or Huanglongbing. It is recommended that growers apply systemic insecticides such as imidacloprid and thiamethoxam every 2 mo after seedling planting, but this practice renders the seedlings insecticide-free and vulnerable to psy ...

Anastrepha ludens; insect pests; fruit flies; storage pests; heat treatment; controlled atmosphere storage; quarantine; mortality; disinfestation; oxygen; air temperature; grapefruits; instars; pupation
Abstract:
... The combination of heat and low levels of oxygen increases mortality to insects infesting fruit compared with either heat or low oxygen alone. This combination treatment shows promise to disinfest commodities of quarantine pests. Heated air/modified atmosphere treatments employ the modified atmosphere (e.g., low oxygen) during the entire treatment interval. There is a positive relationship between ...

Abstract:
... The common bed bug, Cimex lectularius (L.) (Hemiptera: Cimicidae) is known to become associated, from time to time, with clothing or linen. In such locations, it may escape insecticide treatment, and may be carried to new locations. We test the suggestion that laundering is sufficient to kill all life stages and thus help prevent reinfestation and dispersion. We establish minimum temperatures for ...

Abstract:
... Multiple infections of managed honeybee, Apis mellifera, colonies are inevitable due to the ubiquitous ectoparasitic mite Varroa destructor and might be an underlying cause of winter losses. Here we investigated the role of adult small hive beetles, Aethina tumida, alone and in combination with V. destructor for winter losses and for infections with the microsporidian endoparasite Nosema ceranae. ...
