Polyandry contributes to (Coleoptera: Curculionidae) rearing.

Background: Marelli, 1926 (Coleoptera: Curculionidae) is one of the main defoliating beetles in plantations. Biological control with egg parasitoids is one of the main control strategies for this pest and a constant supply of fresh host eggs is required to rear the parasitoids. Polyandry can influence oviposition by increasing female fecundity and fertility; however, the high density of individuals in laboratory colonies can lead to male harassment, resulting in lower reproduction rate.

From the dual cyclone harvest performance of single conidium powder to the effect of Metarhizium anisopliae on the management of Thaumastocoris peregrinus (Hemiptera: Thaumastocoridae).

Insect pests introduced in eucalyptus plantations in Brazil are mostly of Australian origin, but native microorganisms have potential for their management. High quality biopesticide production based on entomopathogenic fungi depends on adequate technologies. The objective of this study was to evaluate Mycoharvester® equipment to harvest and separating particles to obtain pure Metarhizium anisopliae conidia to manage Thaumastocoris peregrinus Carpintero & Dellapé, 2006 (Hemiptera: Thaumastocoridae).

How temperature variation affects white-rot fungi mycelial growth dynamics: a nonlinear mixed models approach.

This study aimed to model mycelial growth in a factorial experiment with two species of white rot fungi growing at five temperatures. The nonlinear models evaluated were logistic, Gompertz, Weibull and von Bertalanffy. The adjustments were performed first by evaluating the fixed and mixed-effects models with random effects, added to the fixed parameters.

Survival of thermotolerant coliforms in municipal biosolids after application in tropical soil cultivated with Eucalyptus.

The increasing production of biosolids in urban areas has been led to a search for alternative disposal avenues of this residue, which is rich in organic matter and nutrients. Agricultural land application of biosolids, motivated by its fertilizing power, is a widespread practice in many countries, but there are safety and regulatory concerns regarding the presence of pathogens in Class B biosolids. In addition, the scarcity of studies under tropical climate conditions raises questions that impede the agricultural use of this residue in some regions.

Longevity and survival of (Hymenoptera: Eulophidae), an invasive gall inducer on , with different diets and temperatures.

The blue gum chalcid, Fisher & LaSalle (Hymenoptera: Eulophidae), causes galls on spp. leaf midribs, petioles and stems Biological aspects need to be studied to assist in developing management strategies and to maintain this insect in the laboratory to rear the parasitoid Kelly & La Salle (Hymenoptera: Eulophidae) that depends on having a supply of seedlings infested by We evaluated the longevity and survival of individual non reproductive females fed with six different diets (pure honey, 50% honey solution, pure honey plus eucalyptus leaves, eucalyptus leaves, distilled water, or no food) and seven different temperatures (10, 14, 18, 22, 26, 30 and 34 °C). fed with 50% honey solution and reared at 14 or 18 °C showed the greatest longevity and survival.
