Native to Africa, the coffee berry borer, Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae: Scolytinae), has gradually invaded most coffee-growing areas worldwide. Adult females colonize the coffee berry and oviposit within galleries in the coffee seeds. Larvae and adults consume the seeds, resulting in drastic reductions in yields and quality, negatively affecting the income of approxi...

The European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae), is a major pest of maize, Zea mays L., in many temperate parts of the world. Genotype-by-environment interaction effects can make relative performance unpredictable and may hamper selection for resistance to European corn borer. The objective of this study was to determine the effect of environment on genotypic react...

The dogwood borer, Synanthedon scitula (Harris) (Lepidoptera: Sesiidae), is a serious wood-boring pest of apple in eastern North America. The recent identification of its sex pheromone and systematic documentation of the effect of a potent behavioral antagonist affords the opportunity to develop pheromone-based management strategies for this important pest. Here we evaluated the potential of ph...

Coffee berries are known to release several volatile organic compounds, among which is the spiroacetal, conophthorin, an attractant for the coffee berry borer Hypothenemus hampei. Elucidating the effects of other spiroacetals released by coffee berries is critical to understanding their chemo-ecological roles in the host discrimination and colonization process of the coffee berry borer, and als...

Cotesia flavipes (Cameron) is a parasitoid responsible for maintaining populations of sugarcane borer, Diatraea saccharalis (F.), below economic levels in south Texas sugarcane Þelds. Transgenic sugarcane expressing the snowdrop lectin (Galanthus nivalis agglutinin, GNA) was developed against the Mexican rice borer, Eoreuma loftini (Dyar), the primary pest of south Texas sugarcane. The potentia...

The lesser cornstalk borer, Elasmopalpus lignosellus (Zeller) (Lepidoptera: Pyralidae) is an important pest of sugarcane (a complex hybrid of Saccharum spp.) in southern Florida. Reproductive and life table parameters for E. lignosellus were examined at nine constant temperatures from 13 to 36 °C with sugarcane as the larval food source. The pre- and postoviposition periods decreased with incre...

We describe an inexpensive and convenient container that solves some common problems associated with storing microcentrifuge tubes in refrigerators and freezers. It is made from a plastic box that comes prepackaged with pipet tips, and we have used FISHERbrand Redi-Tip boxes Catalog No. 21-197-8H (size 200 μL) or Catalog No. 21-197-2E (size 0.5–10 μL) (Fisher Scientific, Pittsburgh, PA, USA) w...

Background: Maize plants are infested with many insect pests. The corn borer, namely: the greater sugarcane borer (the pink borer), Sesamia cretica Led. is one of most injurious insects infesting maize in Egypt and all over world. Results: Results illustrated that mortality percentage within 48 hours S. after feeding 4th instar larvae on leaves treated various plant extracts alcohol or petroleu...

To evaluate the effectiveness of selected insecticides and a botanical extract in management of okra shoot and fruit borer, Earias vittella an experiment was conducted in the field Laboratory, Department of Entomology, Bangladesh Agricultural University, Mymensingh during January to May 2011. Effectiveness of two synthetic insecticides (Kinalux 25 EC and Ecofuran 5 G) and a botanical (Neem leaf...
