Facultative and non-facultative sex ratio adjustments in a
15 If parental allocation to each offspring sex has the same cost/benefit ratio, Fisher's 16 hypothesis predicts a sex ratio biased towards the cheaper sex. However, in 17 dimorphic birds there is little evidence for this, especially at hatching. We 18 investigated the pre-fledgling (i) sex ratio, (ii) body condition and (iii) sex19 differential mortality in a population of the glossy ibis (Ple...

Thrips tabaci Lindeman (Thysanoptera: Thripidae), a cosmopolitan pest insect, is subdivided into at least three genetic lineages that have different biological characters, such as reproductive mode and resistibility to insecticides. Since the lineages are discriminated only by mitochondrial DNA, there is a possibility of gene flow among lineages at the genomic level. Nine polymorphic microsatel...
متن کاملNine facultative endosymbionts in aphids. A review
Aphids are frequently engaged in mutualistic associations with endosymbionts. Symbionts are bacterial or fungal microorganisms that can be obligate or facultative to aphids. Research showed facultative (or secondary) symbionts have numerous effects on their host aphids such as resistance to heat shock, parasitoids and fungus etc., which may consequently promote a co-evolution between symbionts ...
متن کاملThrips Management in Arkansas Cotton
Thrips populations increase in the spring on early wild host plants and most likely on wheat. These hosts of thrips start to dry beginning in early May until midJune and thrips begin to migrate to more favorable food sources. Unfortunately, this is about the same time that cotton begins to grow. The large host acreage for thrips and their reproductive capability create a situation, in most year...
