Biotic potential and reprodutcive parameters of Spodoptera eridania (Stoll) (Lepidoptera, Noctuidae) in the laboratory: This study aimed to evaluate the biotic potential and reproductive parameters of Spodoptera eridania (Stoll, 1782) under controlled conditions (25 ± 1°C, 70 ± 10% RH and 14 hour photophase). The longevity, pre-, postand oviposition periods, fecundity and fertility of 15 couple...

The present studies examined the use of plant extracts viz., Niaz boo (Ocimum basilicum L.), Gardenia (Gardenia jasminoides (J Ellis), Sanatha (Dodonaea viscosa Jacq.) and Lantana (Lantana camara (Linn.) as oviposition attractant and larval growth promoter/inhibitor on the house fly (Musca domestica L.). The plant chemicals in different final concentrations (25 and 50%) were mixed in a larval m...

background & aim: tetranychus urticae koch is one of the most important pests of crops, ornamental and greenhouse plants in the world and, can damage to 900 plant species. resistances to pesticides and acaricides have guided researches to introduce new methods to control t. urticae. botanical pesticides are an important group of natural productions that are usually safer than conventional p...

Two artificial oviposition sites containing aged alfalfa pellet infusion were exposed to natural populations of Culex quinquefasciatus in San Antonio, Texas, for 3 years. Numbers of egg rafts were counted daily and compared to weather data from a nearby station. Egg rafts were generally most numerous in summer months, declining in fall and increasing in spring. Oviposition occulred in winter on...

Oviposition site-selection in insects is mediated through innate recognition templates (IRTs) tuned to specific chemical cues. These cues aid gravid insects in choosing suitable oviposition sites and may even enhance the fitness of their offspring by warding off predators and parasitoids. However, studies on the evolution of oviposition site-selection and cues instigating oviposition in domesti...

To determine the influence of physical factors on oviposition of Lutzomyia migonei (Diptera: Psychodidae) under laboratory conditions, two sets of experiments were performed. The first test was to determine the influence of the size of pots on oviposition. Gravid flies were placed individually or in groups in different oviposition pots. The number of eggs laid, oviposition time and survival of ...

Insect oviposition on plants frequently precedes herbivory. Accumulating evidence indicates that plants recognize insect oviposition and elicit direct or indirect defenses to reduce the pressure of future herbivory. Most of the oviposition-triggered plant defenses described thus far remove eggs or keep them away from the host plant or their desirable feeding sites. Here, we report induction of ...
