Answer 1

Answer:

The cultivation of tropical fruit trees has grown considerably in the state of Bahia, northeastern Brazil. Some of these have been severely attacked by phytophagous mites, which are usually controlled by the use of chemical pesticides. However, there is today a growing interest for the adoption of less aggressive measures of pest control, as for example the use of predatory mites. Most of the plant-inhabiting predatory mites belong to the family Phytoseiidae. The objective of this paper is to report the phytoseiid species found in an intensive survey conducted on cultivated tropical fruit trees in fifteen localities of the southern coast of Bahia. Measurements of relevant morphological characters are provided for each species, to complement the understanding of the morphological variation of these species. Twenty-nine species of sixteen genera were identified. A key was elaborated to assist in the separation of these species. Fifteen species are reported for the first time in the state, raising to sixty-six the number of species of this family now known from Bahia. Seventy-two percent of the species collected belong to Amblyseiinae, followed by Typhlodrominae (21%) and Phytoseiinae (7%). The most diverse genus was Amblyseius. Amblyseius operculatus De Leon was the most frequent and abundant species. Studies should be conducted to evaluate the possible role of the most common predators as control agents of the phytophagous mites co-occurring with them.

Introduction

Cultivation of tropical fruit trees has grown considerably in the state of Bahia, northeastern Brazil, in the last years (Santos-Serejo et al. 2009). Several mite species have been reported on those plants, some causing economic losses (Moraes and Flechtmann 2008). These are usually controlled by the use of chemical pesticides.

However, there is today a growing interest on the use of less aggressive and less toxic strategies to control those organisms. Predatory mites of the family Phytoseiidae are considered important biological control agents of pest mites, and some phytoseiids are commercially available for the control of pest mites in several countries (Hoy 2011). There is an interest to implement the use of phytoseiids for the biological control of pest mites in orchards of tropical fruit trees in coastal Bahia, and the determination of the naturally occurring phytoseiids in that area is considered the first step in the implementation of a biological control program.

The objective of this paper is to report the phytoseiid species found in an intensive survey conducted on cultivated tropical fruit trees in the southern coastal region of Bahia, providing a key to help the separation of the species collected.

Dear Sirs

We are thankful for your sending the books as per our order dated 11 March, 2017.

However, on opening the parcel, we have found that the books are damaged. The title pages of almost all the books are badly tom.

The poor quality of packing paper seems to be the cause. The despatch clerk also left the parcel loose. The books need to be replaced. I am sending them back at your cost.

Prompt action is requested.

Yours
