Estimation of Sugar Loss Due to Infestation by the Stem Borer , Chilo Sacchariphagus , in Mauritius
To justify the cost effectiveness of sex pheromones for the control of the stem borer Chilo sacchariphagus Bojer in sugarcane, the relationship between the per cent internodes bored and the various yield parameters, i.e. pol % cane, purity, fibre % cane, industrial recoverable sugar % cane (IRSC) and weight had to be determined. Analyses were made on cane samples, with varying degrees of infest...
متن کاملType and Distribution of Sensilla in the Antennae of the Red Clover Root Borer, Hylastinus obscurus
In order to determine the type, distribution, and structures of sensilla, the antennae of the red clover root borer, Hylastinus obscurus Marsham (Coleoptera: Curculionidae: Scolytinae), were examined by light and electron microscopy (both scanning and transmission). Four different types of sensilla were identified in the club, and one type of chaetica was found in the scape and funicle of both ...
متن کاملon the equivalence of constructed-response and multiple-choice : stem-equivalent, stem non-equivalent but content equivalent, and stem and content non-equivalent items in reading comprehension using multifaceted rasch
the present study investigated construct equivalence of multiple choice (mc) and constructed response (cr) item types across stem and content equivalent mc and cr items (item type ‘a’), non-stem-equivalent but content equivalent mc and cr items (item type ‘b’), and non-stem and non-content equivalent mc and cr items (item type ‘c’). one hundred seventy english-major undergraduates completed mc ...
The Coffee Berry Borer (Coleoptera: Curculionidae) in Puerto Rico: Distribution, Infestation, and Population per Fruit
The coffee berry borer (CBB) (Hypothenemus hampei: Ferrar) was first detected in Puerto Rico in 2007. Its distribution since then has been extensive, but not extensively documented. An island-wide survey was carried out from August to November 2014 (the coffee production season) to assess CBB distribution, infestation, and population per fruit. The CBB was well-established throughout the coffee...
متن کاملInfestation and hydraulic consequences of induced carbon starvation.
Drought impacts on forests, including widespread die-off, are likely to increase with future climate change, although the physiological responses of trees to lethal drought are poorly understood. In particular, in situ examinations of carbon starvation and its interactions with and effects on infestation and hydraulic vulnerability are largely lacking. In this study, we conducted a controlled, ...
