ABSTRACT Silicon is an inducer of plant resistance to arthropod pests, being a promising strategy for integrated management. The aim this study was evaluate the effect silicon on biological, reproductive and population aspects parental F1 generations two-spotted spider mite strawberry plants. Potassium silicate, nanosilica water were applied Two-spotted females confined leaf disks oviposition a...

1. Locating an optimal oviposition site can be a challenging task for female insects, especially when dealing with patchy, unpredictable and ephemeral food source such as carrion. Understanding the biotic abiotic parameters that influence behaviour of necrophagous flies is not just great biological importance but also essential their application in legal investigations. 2. In this study, we mon...

The improvement of techniques for the mass rearing predators in laboratory, including age mating is important to obtain largest number individuals biological control programs. purpose this study was evaluate females’ fecundity predator Podisus fuscescens (Dallas, 1851) (Hemiptera: Pentatomidae) with different pre-mating periods. females were mated immediately after emergence (T1) or one (T2), t...

Oviposition strategies and mechanisms of host selection in parasitoids may be crucial for the success of parasitization and parasitoid production. These aspects are far less known in tachinid parasitoids than in hymenopteran parasitoids. Depending on the species, parasitoid flies may adopt direct or indirect oviposition strategies. The 'direct type' females lay eggs on or, in relatively a few s...

Few studies have examined the genetic architecture of population differences in behaviour and its implications for population differentiation and adaptation. Even fewer have examined whether differences in genetic architecture depend on the environment in which organisms are reared or tested. We examined the genetic basis of differences in oviposition preference and egg dispersion between Asian...

Thediamondbackmoth,Plutella xylostella (L.) (Lepidoptera: Plutellidae), amajor pest of cruciferous crops throughout the world, has demonstrated an ability to develop resistance to many different classes of insecticides, including proteins from Bacillus thuringiensis that are expressed in plants (Bt plants). The ovipositional preferences and larval survival of strains (resistant strain, RR; hete...

The pea weevil, Bruchus pisorum L. is a major insect pest of field pea, Pisum sativum L. worldwide and current control practices mainly depend on the use of chemical insecticides that can cause adverse effects on environment and human health. Insecticides are also unaffordable by many small-scale farmers in developing countries, which highlights the need for investigating plant resistance trait...

We investigated effects of temperature, at 70% RH, on the reproductive parameters of the parthenogenetic psocid Lepinotus reticulatus Enderlein (Psocoptera: Trogiidae). The lowest fecundity (21) was at 35 degrees C and the highest (41) at 27.5 degrees C. At 22.5, 25, and 27.5 degrees C, peak oviposition rates (eggs/female/week) occurred in week 3 and were 4.7, 6.6, and 7.8, respectively; also 5...
